Info to be known before buying laptop!

This question will intrigue a lot for anyone..”Which laptop is the best laptop?”….

To answer this question I should speak out some concepts about computing and laptops.

1)Processors :-

Processor is the most important part of laptop.Today normal laptops should have Processors like

1)Intel Core 2 Duo Pxxx and Txxx series

2)Intel Core 2 Extreme(Quad-core Xxxx)image

3)AMD Turion 64

4)AMD Turion 64 X2

5)AMD Turion Ultra

6)Intel ATOM

7)Intel Centrino

Intel Core 2 Duo (Merom)

This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more current consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).

Features are 2 cores, a 64-bit EM64T command amplification and 2 or 4 MB L2 Cache and 291 millions of transistors, which are finished in 65 nm. Furthermore all types support "Execute Disable Bit" technics, SSSE3 (SSE4), Enhanced Speedstep,  LaGrande and most types the virtualisation technics (VT) Vanderpool.

The Core 2 Duo for laptops is identical to the desktop Cure 2 Duo processors but the notebook-processors work with lower tensions (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.

Now, the Core 2 Duo exists in the following versions (sorted by performance):

The energy need of the processors is marked by pre-set letters in front of the type designation (number).
X ... Extreme (fastest) version with the highest current consumption
E ... >= 55 Watt (Desktop PCs)
T ... 30-39 Watt (Standard laptop CPUs)
P ... max 25 Watt
L ... 12-19 Watt (Low Voltage)
U ... <11.9 Watt (Ultra Low Voltage)

The 4-digit sequence indicates the type series (first digit) and performance (other digits). The Core 2 mobile processors ought to get 5XXX and 7XXX (at present T2XXX for Core Duo and T1XXX for Core Solo).

In Summer 2007, the Santa Rosa update has been published with minimal improvements (like the faster FSB 800 and Dynamic Acceleration - the overclocking of one core, when the other one is idle).

In January 2008, Intel introduced new T9xxx and T8xxx Core 2 Duo processors based on the new "Penryn" core. These processors are fabricated in the 45nm (the predecessors in 65nm) and offer a bigger level 2 Cache (3 and 6 MB). Furthermore, Penryn got a faster division unit and 47 new SSE orders (SSE4 called).

Core 2 Duo was presented in 31. July 2006 with the following versions (versions with FSB 800 and Dat - dynamic acceleration technology in 05.09.07):

U7500, 1.06 GHz, 2 MB L2, 533 MHz FSB, VT - 10 Watts

Intel Core 2 Extreme (Merom, Penryn)

The fastest Core 2 Duo variants of Intel are called Core 2 Extreme. Technically, these processors are based on a Merom/Penryn (X9000) core like all other Core 2 Duo  processors,  too.

X7800, 2.6 GHz, FSB 800, 4 MB L2, 44 Watt TDP, Merom, 07.2007 image
X7900, 2.8 GHz, FSB 800, 4 MB L2, 44 Watt TDP, Merom, 09.2007
X9000, 2.8 GHz, FSB 800, 6 MB L2, 44 Watt TDP, Penryn, 01.2008
X9100, 3.06 GHz, FSB 1066, 6 MB L2, ? Watt TDP, Penryn, 06.2008

Intel Core 2 Solo (Merom)

This is the successor of the Core Solo and technically a Core 2 Duo with only one core. It will be available for laptops starting with the 3. quarter 2007 and only as an Ultra Low Voltage (ULV). Therefore the core tension is very low (=economic). 2 versions are planned at moment:

  • U2100, 1.2 GHz, 1MB L2 Cache, 533 MHz FSB, 5 W max. TDP
  • U2200, 1.06 GHz, 1MB L2 Cache, 533 FSB, 5 W max. TDP

Intel Core Duo (Yonah)

Pentium M successor
Double Core processor with a very good relation of performance to current consumption. The 2 MB L2 Cache are used together by the double. The maximum capacity of 31 watts is only 4 watts more than with the Pentium M (predecessor). Both cores are lowered automatically and independently of each other by speed steps down to 1 GHz. In addition it now supports also SSE3 instructions.

After first benchmarks the Core Duo completes all tests at least just as fast as a equivalent Pentium M. With applications, which were designed for multi-processors, the performance can be nearly twice as fast as with the Pentium M (e.g. CineBench around 86% fast)

Models (clock, TDP):
T2700 (2.33 GHz, 31 W, FSB 667 MHz)
T2600 (2.16 GHz, 31 W, FSB 667 MHz)
T2500 (2.00 GHz, 31 W, FSB 667 MHz)

T2250 (1.73 GHz, FSB 533, MHz)
T2050 (1.60 GHz, FSB 533 MHz)
T2050E (1.60 GHz, FSB 533 MHz): current saving version with 1.3 instead of 1.4 Volt supply voltage

U2500 ULV, 1.20 GHz, 9.5 W, FSB 533 MHz
U2400 ULV, 1.06 GHz, 9.5 W, FSB 533 MHz

Pentium Dual Core T2060: 1.6 GHz, FSB 533 MHz, 1 MB L2 Cache (the return of the name Pentium, though Yonah core)
Pentium Dual Core T2080: 1.73 GHz, FSB 533 MHz, 1 MB L2 Cache

Intel Core Solo

Single core version of the Core Duo and successor of the Intel Pentium M; Because of the 65nm reduced structure width also smaller current consumption than Pentium M (maximally 27 Watts); the performance is comparable with the equivalent clocked Pentium M (somewhat faster because of a few improvements).

T1200 mit 1.50 GHz, FSB 667 MHz, 2MB L2 Cache
T1300 with 1,66 GHz 2MB L2 Cache
T1350 with 1.86 GHz, FSB 533 MHz, 2MB L2 Cache (about the same level like Pentium M 750)
T1400 mit 1.83 GHz, FSB 667 MHz, 2MB L2 Cache

Ultra low voltage models (maximum 5.5 Watt):
U1300 mit 1.06 GHz, FSB 667 MHz, 2MB L2 Cache
U1400 mit 1.20 GHz, FSB 667 MHz, 2MB L2 Cache
U1500 mit 1.33 GHz, FSB 667 MHz, 2MB L2 Cache


AMD Turion X2 Ultra

The Turion X2 Ultra was introduced in Q2 2008 and the core is based on the old K9 architecture (Turion 64 X2) with some K10 (Dektop Phenom) parts like the Crossbar-Swithc, HyperTransport 3.0 link, memory controller). Because of the bigger L2 cache (of the Ultra models), the performance is a bit better than a similar clocked Turion 64 X2. Furthermore, the current consumption went a bit down. Still the performance is not compareable to a similar clocked Core 2 Duo (which feature up to 6 MB L2 Cache).

AMD Turion64 X2

64 bit dual core (2 core) processor, code name Taylor (2 x 256 KB L2) and Trinidad (2 x 512 KB L2), DDR2-667 support, Pacifica (AMD-v) virtualisation technics, 31-35 W TDP, socket S1, 90 nm fabrication, separated L2 Caches, integrated 333 MHz DDR, 800 MHz Hypertransport

AMD Turion 64 X2 is intended to be positioned against the Intel Core Duo was presented in 17. May 2006. The current consumption is not higher than with Centrino-Duo-notebooks (TL-45 with ATI Xpress and Mobility Radeon X300). This means, that approximative the same battery runtime and fan functions can be expected (with this chipset). However, the performance was 20% below the T2300 (1.66 GHz) due to the lower L2 Cache (Core Duo has 2048 Kbyte shared L2 Cache). Nevertheless, the performance is sufficient.

In March 2007 a Turion 64 with reduced structure was announced (as a response to Intels Santa Rosa Core 2 Duo), which have up to 2.3 GHz.

TL-50 1.6 GHz 2 x 256 KB L2 Cache, 31 Watt TDP
TL-52 1.6 GHz 2 x 512 KB L2 Cache, 31 Watt TDP
TL-56 1.8 GHz 2 x 512 KB L2 Cache, 33 Watt TDP, 65nm (31 Watt after May 07)
TL-58 1.9 GHz 2 x 512KB L2 Cache, 31 Watt TDP, 65nm
TL-60 2.0 GHz 2 x 512 KB L2 Cache, 35 Watt TDP, 65nm
TL-64 2.2 GHz 2 x 512KB L2 Cache, 35 Watt TDP, 65nm
TL-66 2.3 GHz 2 x 512KB L2 Cache, 35 Watt TDP, 65nm

AMD Turion 64

This is a derivative of the Athlon 64 with SSE3 and nx storage protection, 32 and 64 bit support, integrated memory controller for PC3200 memory, current save mode, HT800. The ML versions have a TDP of 35 Watt and the MB versions 25 Watt.

MT-30 / ML-30 (1.6 GHz, 1 MB L2)
MT-32 / ML-32 (1.8 GHz, 512 KB L2)
MT-34 / ML-34 (1.8 GHz, 1 MB L2)
MK-36 (2.0 GHz, 512 KB L2, 31 Watt TDP)
MT-37 / ML-37 (2.0 GHz, 1 MB L2)
MT-40 / ML-40 (2.2 GHz, 1 MB L2)
ML-42 (2.4 GHz, 512 KB L2)
ML-44 (2.4 GHz, 1 MB L2)

Regarding the consumption MT might be very similar to a Pentium M. The speed is moderate and approximately as fast as an Pentium M with equivalent clock speed.

AMD Athlon 64 X2

In contrary to the rare cases, where Desktop Athlon 64 X2 processors are inserted in DTR laptops, AMD introduced in summer 2007 the "Athlon 64 X2 Dual-Core processors for laptop PCs" series with CPUs, which are based on the Turion 64 X2 core. The CPU is designed for socket S1 and contains an integrated DDR2 memory controller.

AMD Athlon 64 X2 TK-53, 65 nm, 1700 MHz, 31 W TDP
AMD Athlon 64 X2 TK-55, 65 nm, 1800 MHz, 31 W TDP

NoTE: AMD Turion is the most widely accepted processor by Notebook Manufacturers.

There are lot of things I had to say about these processors…….

These Specifications speak a lot Model name,Processor clock speed,amount of cache in the processor and in some specification You can find FSB(Front Side Bus) in MHz its the speed..This FSB is like tree in the whole Computer hardware which connects all the components from Processor to external components like Printers,USBs etc…

The Watt reading is the amount of power processor takes while working.Higher the amount of Watt heavier is the heat produced.So,Laptop manufacturers should design to dissipate the processor’s heat.

The immediate difference one may find is their identifying model numbers.

  • nm stands for nano meter.
  • Code name of Intel processors comes from the a name of any local neighborhood near by to the Intel development facility in which it is developed

Intel 65nm processors are the 1st batch of Core architecture product code named Conroe / Conroe XE / Conroe L / Allendale / Merom / Merom XE / Kentsfield / Kentsfield XE.

Intel 45nm Penryn processors are the second batch of the successful Core architecture with Code name Penryn / Wolfdale / Yorkfield / Yorkfield XE.

45nm consume less power, produce less heat, thus increase overclock limit. And yes, the board which accepts 45nm processor can accept 65Nm also.

 The big question is In Today’s market U can find only Core 2 Duo T and P series for their efficiency.So,what to select?

P series is the best as they consume low power when compared to T series Processor!.If your Budget is enough to get Notebook with Processor T700 above or p700 above or Processor speed more than 2GHz try for 2.4GHz and above..then I can say that your notebook is powerful..See that FSB is higher than 667 MHz try for 800MHz ..

There are very less number of Laptops with Quad-Core or Core 2 Extreme processors and presently this processor is considered for high Graphical or Engineering development/usage.



There should enough amount of RAM to run your programs..If you open 4-5 High end applications like Adobe Photoshop, Matlab, Auto CAD, Netbeans IDE etc..or any high graphical game..they consume a lot of RAM.To make your programs to run smoothly You need heavier RAM.Windows Vista needs minimum of 2 GB RAM which gave strict message to manufacturers that 2 GB Ram is normal these days..So,For anyone 4GB to 6GB of RAM will give an handful  hope to run future applications.

RAM also has speed of functioning just like FSB.So see that its speed of functioning is also 667MHz above and try for 800MHz …Dont bother about DDR3 or SDRAM they are the latest technology in RAM.Just know that U get the standard new technology in the market.Don’t believe the dealer..see the specs..

3) Hard Dish(HDD) or SSD :-

Hard Disk is like the capacity of the laptop.They vary with their capacity like 160GB,250GB,320GB500GB etc…image if you are a hardcore gamer then try to get any HDD with 7200 rpm.For a 15”in laptops 320GB HDD is commonly found while 17” laptop has different setup of HDDs.Some 17” laptops have 2 Hard disks giving options to customize according to your need in Dell XPS 1730 It has 2 hard disks giving capacity range from 160GB to 1000GB using both.While in some other 17” laptops have conventional HDD means only one but a larger  one.

In HDD there will be a motor.Its speed is given in specs like 5200 rpm or 7200 rpm.A 5200 rpm HDD is sufficient for normal applications but a Game needs higher RAM, heavier flow of data from HDD to RAM, AGP card.To meet this demand of data from HDD 5200 rpm speed is not sufficient.So, HDD with 7200 rpm is needed.Consider this option as a valid one when You are trying to get a laptop beyond $500-$600.

SSD is a lot different when compared to HDD.SSD(Solid State Drive) doesn’t have any motor and it uses switching circuit technique to store Data.So,rather than storing and retrieving data using magnetic  disc it uses electronic circuits.So,though they are costlier they give longer life as they don't have any rotating component like motor inside.

4) LCD :-

Many customers  don’t consider this as an important thing.They think  they are getting value of money they pay for laptop.Full HD resolution is 1920 X 1200.The future of TV is full HD.Full HD asks extra bucks but the clarity it provides differs a lot.If U connect display to a TV having full HD feature,then there will be a thrill in clarity.

5) Graphics Card :-

This is the most important part of Laptop.A laptop with Graphics card does a lot of things easily when compared to normal one.Today every Os has a lot of Graphics which easily slows the RAM.Any application needs RAM whether it may be a media software,game,graphics and mostly when U play a game RAM is consumed more.its not because of your game but its because of RAM property.

lets think RAM runs at the speed of ‘X’ and gives ‘A’ amount of its memory for a game.But a game needs 2.5X of RAM speed to keep up its Graphics.RAM couldn’t run at speed higher than X.So, Game takes of 2.5A amount of RAM for speed of X.Simply saying it takes a lot of RAM.To address this issue Graphics Cards are concerned.what AGP(Accelerated Graphics Port also called Advanced Graphics Port) Card does is It grabs all the applications asking for Graphics from RAM and executes them at required speed,means either 2.5X or 4X.

There is other way to get these Graphics executed without AGP card.This is considered as Extreme tuning of processor.Processor is the heart of CPU.If it runs faster everything is fast.So,Processor speed is increased manually.This process of increasing speed of any processor is called ‘over-clocking’.A normal 2.4GHz processor can run at 4-5GHz by using the settings in the BIOS,but I must caution this could kill the processor If U are not a professional.Change the setting in BIOS to overclock the processor and also increase the voltage levels of FSB and RAM approximately to the required level.GET NO2 cylinder as its the best cooling agent.When a Processor is Overclocked it delivers a lot of heat enough to kill It.Get a temperature equipment enough to measure temperatures 300C.If possible get a copper plate or small copper bowl.keep aside the Fan which is on the processor, donot plug it off..let it plug in or else whole Mother board will turn off.Keep the copper bowl on the processor, stick the sensor of temperature measuring equipment below the plate/bowl..because above the plate/bowl NO2 will be delivered which could run the temperature to get the exact temperature sensor should be sticked at below the bowl..but aside to the processor. Now change the setting of bios and restart the system.If U are running Xp U can see that It will not take more than 10 seconds to get login screen…whhooilaaa!!!!…now,run a game like NFS MW/FEAR/GRID/ game with high graphic content.. and see the way it runs..U will be mesmerized as if U are in third world…See that whenever the temperature is crossing 50C then start leaving out NO2 in to the copper bowl/plate which is on the processor.(Wow!!I did more than 100 times and this had cost me more than $25000 to get a big 25KG NO2 cylinder)

OK!!out of this overclocking now….Any AGP card is same as RAM but with faster memory modules.Just as RAM AGP card also comes with different capacity like 256MB,512MB,1GB etc…Any laptop at the range of $600 and above has a graphics card.There is a lot off competition but only 2 MNC’s are flourishing the competition.They are Nvidia and ATI(AMD).They are competing in AGP card segment since decades.The best graphics card is the most difficult question to answer.To know the answer see this toms’s hardware site .

6)Other Features :-

Well i discussed a lot about internal/necessary  parts of a laptop hardware.There are many things like image touch pad,finger print reader, backlit keyboard,number of USB ports, HDMI port to connect LCD with External TV,fall sensor for HDD,BD-ROM,6 or 9 cell battery,Wi-Fi,Bluetooth,Wireless Network card,TV Tuner,External Mouse and keyboard,Docking stations etc... which can be understood just by see the package or browsing the Net.

Thats it guys,I told what I thought to share with U and remember one thing…..Guess the amount of time U’ll be working with the new coming laptop.if U are thinking that U’ll be with the new beast for at least 4-5 years then simply get 2 year warranty along.

Guys I’ll be touching U with post on recommended laptops…

Do u know about Scotoma??

image Scotoma is a typical spot(s) caused by visual problems surrounded by the normal visual activity.The picture shows a case of Scotoma.It is said that this Scotoma is not a constant spot.It moves around in the vision.

Many Doctors say that Scotoma is the problem of collision of the vision of the two eyes. Even a normal person who is not seeing such light/dark spots in his vision has Scotoma unconsciously.For some people it is very much scintillating like no channel on old TV(see the  pic below).


So,what's the reason for such conscious vision?.

The reason is not that one eye is not able to catch the picture .Lets take this way.we can’t see the objects that are extreme right with left eye but in normal vision we could see the whole objects??This is due to the optic nerve which sends the visual activity of both eyes to brain.And Brain overlaps the visionary part that is same in both images of respective Left and right eye and adds the right portion of right eye along with left portion of left eye.Each eye has its respective optic nerve.If there is a problem with this nerve then such problems arises in vision.So, visual signals absent in both eyes are mixed.If optic nerve got damaged enough which is unable to send signals then such spots will occur as these spots are not conveyed to brain By the Optic Nerve.

See this Scintillating Video of Scotoma.

Think Big, Dream Big –an Electric Car


 image  Well, We see a lot of fuzz about clean & green energy .have You ever considered what are the advancements that are going on in Automobile Industry for such Energy.If yes/No,lets see some concepts here..

Do anyone know Musk,

Musk is a 37-year-old technology entrepreneur who became extremely wealthy when eBay bought PayPal, which he had co-founded. A lanky South African, he is using that wealth to finance two quixotic efforts. The first is SpaceX, a company he hopes will one day make it possible to colonize Mars. (I kid you not,Let us wish for this success also.)

The second is Tesla Motors, which was started in 2003 — Musk became its chief backer and board chairman in early 2004. After raising $150 million and going through four years of technological and internal struggles, the company has begun manufacturing the first-ever all-electric sports car, the Tesla Roadster. Its base price is $109,000. And if Musk is willing to concede that the Roadster, by itself, isn't a world-changer, he fervently believes that the technology Tesla has created — technology that gives the car a range of 227 miles per battery charge, and enough acceleration to go from zero to 60 in under 4 seconds — will indeed change the world. The age of the electric car, he is convinced, has dawned.

The Tesla Roadster is a gorgeous sports car. That's not a surprise: one of Tesla's goals was to prove that an electric car didn't have to look stodgy — or resemble something out of "The Jetsons." Tesla's other goal, though, was to show that an electric vehicle could provide a driving experience that was a good or better than any finely tuned sports car.

They appear to have succeeded at that as well. "My experience was highly positive," said Don Sherman, the technical editor at Automobile magazine who test-drove it last December. "It was a very exciting, very interesting piece of work that I found quite appealing." Though I'm no auto expert, I'd have to agree. I took the wheel for an hour last week and came away exhilarated by how quickly it accelerated, and how beautifully it handled. For the first time in my life, I had car lust.

So far the company has delivered four cars, with 27 more in production. It has 1,080 customers waiting patiently for a Roadster, which is a year behind schedule. (Google founders Larry Page and Sergey Brin, both Tesla investors, are scheduled to get cars seven and eight.) Tesla expects to be delivering four cars a week soon, a number it eventually hopes to double.

But for all its sex appeal, the Roadster only hints at Tesla's real ambition. By the end of 2010, Musk and his executive team expect to be manufacturing a five-seat, all-electric $60,000 sedan. This, however, will be a much more expensive and difficult task — and many auto experts doubt that Tesla can pull it off. Which raises the question of whether the era of the electric car is really about to begin, as Musk believes — or whether the Tesla Roadster is little more than an expensive toy for rich people.

In the documentary "Who Killed the Electric Car?" — about the EV1, an all-electric car General Motors began making in 1996 and killed once and for all in 2003 — the filmmakers posit the theory that the vehicle was done in by a grand conspiracy involving the oil industry, the Bush administration and the car industry. But that's not what happened. Gas was cheap when the EV1 was on the market; auto buyers preferred S.U.V.'s. And the technology didn't exist to allow the EV1 to become a viable mass-market automobile. Among its flaws, the EV1 used a nickel metal hydride battery that couldn't get more than 75 miles before needing a charge.

"My daily commute was 37 miles one way," wrote a man named Michael Posner on a Web site called The Truth About Cars, who drove an EV1 for several weeks back in 1997. "Every trip was loaded with drama," he added. "If I went to lunch, I gave up a few precious miles. That could mean disaster." At General Motors, they took to calling this problem "range anxiety." Is it any wonder the car didn't catch on?

Jump ahead a decade. Oil is so expensive that everybody is thinking about alternatives to $4.50-a-gallon gasoline. At the same time, the technology that makes electric cars possible has greatly improved. The development of lithium ion batteries, in particular, was such a great leap forward that it has made it possible, with enough additional innovation by electric car companies, to produce vehicles that get more than 200 miles. Suddenly, an electric car seems viable.


Other automakers -- including Chrysler, Mitsubishi and Ford -- also touted their plans for cars equipped with electric motors as the industry both seeks to overcome the current crisis that has decimated sales and meet increasingly tough environmental and carbon emission standards.
Only European giant VW bucked the trend, saying its answer to the electric car would come out "in the coming decade."
European drivers could be silently cruising around in the Ampera by the end of 2011 -- the first 60 kilometers on pure electricity augmented by another 500 kilometers of extended range from a gasoline engine, which would generate less than 40 grams of C02 emissions per kilometer.

    The Ampera presented in Geneva was a white four-door sedan with a hatchback -- and a set of front headlights that created a menacing, masculine impression. An Opel official demonstrated how the car could easily be plugged into any household electrical supply. "This is the kind of game-changing technology that the auto industry needs to respond to energy and environmental challenges," President of GM Europe Carl Peter Forster said. Mitsubishi Motors Corp. said it has reached an understanding with Peugeot Citroen PSA to sell its new electric car "i MiEV" to European customers as early as late next year.

Mitsubishi's president Osamu Masuko said the collaboration could help pave the road to "tomorrow's sunny days" for the automotive industry, which is struggling amid the global economic downturn and a decline in global sales. Peugeot will sell the car under its own brand in Europe, while Mitsubishi will launch the car in Japan this year. The four-door electric-only hatchback produces no carbon dioxide emissions and has a top speed of 130 kilometers per hour (80 mph). It has a range of 145 kilometers once its 330-volt lithium ion battery is charged for 14 hours.

By contrast, Ford and Chrysler showed only concept cars that illustrate the company's thinking about electric cars.
Ford's presented at its stand a five-seater passenger vehicle called the Tourneo developed for European markets by Smith Electric Vehicles, part of the Tanfield Group, which developed the Ford Connect van in the United States.
"The plan is to go into production as soon as we feel the market is ready for production," Tanfield CEO Darren Kell said.
Chrysler showed its Dodge Circuit EV sports car, which was unveiled in Detroit.

    VW is moving more slowly. Chairman Martin Winterkorn said the German automaker would launch its first electric vehicle "in the next decade" ."Announcements alone have never brought new technology onto the road," Winterkorn told a presentation at the Geneva Auto Show. "It's a long path to safe electric cars that are available for everyone. We are not talking about being the one with the fastest solution. We want the best solution". "We expect to increase market share. Not volumes," Winterkorn said. Translation: VW cars will outsell their competitors, even as new car sales shrink.

This could be the reason for GMAIL outage..



There was a problem accessing Gmail 2 days before, many Business and transactions have been stalled for about 4-5 hours . Google admitted that its their fault with bundled servers. Google also admitted that Corporations?Business using special Gmail service could get such service for 15 days freely.This is confirmed here.

I thought that Why My Id was not targeted But today I found 300 mails in spam .Wondering I opened and found that Google had recovered the fault they encountered very quickly !!Click to enlarge the image ..Its clear that Google specified the warnings in Mails containing unknown and very dangerous sites..
