I got up this morning to check my e-mail so when i opened my laptop i pressed the powere button to resume it from hibernation and about 2 minutes later the hardrive stoppped and the screen went blank.

It was plugged into the AC adapter and had the battery in. i went to a bunch of forum the past few hour trying to figure out if it was a common problem it seems like it may be.

But first i checked to see if the AC cable was working. the light was on and then i checked it with my multimeter output was 19.87v within spec according to the lable on the adapter. So i removed the battery and plugged in the adpter again, nothing. Then i went to my desktop to search online.
I found a thread about a common problems with the PGN models and it was about disconnecting the internal system battery. it told me to remove the keyboard and then the battery should be there. nothing is under the keyboard execpt for the top case of the cd-rom and the connector for the keyboard. i found another thred about the AC jack being defective. i removed it from the computer completely and plugged it into the adapter with the adapter into the wall same thing checked voltage 19.87v so the jack has clean good connection. .

I read it may be the power board or the mother board. im not sure if its the same thing or not. i know about electronics but not about PCs or Laptops. Any help in diag would be muchly appreciated.

Do the clicks sound like their coming from the hard drive or somewhere else in the computer?

no not from the hardrive, they are really quiet clicks almost unnoticable, it seems they are comming from the battery area or close proximity to the battery.

Try starting it with the battery removed and see if that works.

Ok the clicks sound like they might be the computer trying to start up but for whatever reason it does not have enough power. Similar to starting a car without any petrol. This means that it is probably your powersupply/adaptor. See if you can fine a new one cheap on ebay or something and try that. Or if you have a friend with a similar model laptop then borrow his and see if it makes any difference.

from original post:

its getting power at least from the ac-dc adapter. or the cable is providing power i am sure of that. the cable is good.

My Sony VAIO VGN-FS760/w has done the same exact thing. A knowledgeable friend feels it is the that the internal power source has gone bad. Just heard of a recall yesterday on Sony laptops for overheating, but not this model. I looked around for a used model so I could just slip in the hard drive instead of paying an arm and leg for mine to be repaired, but everyone I looked, it seemed that all the ones offered for sale have this very same problem.

ANYONE HAVE ANY IDEAS?

I am having the same problem with my VAIO. It was in hibernation working fine, later it was completely dead. I tried using someone elses battery ( we all have identical VAIOs from work), and I also tried using the dock to route the AC through the dock port in case it was something with the AC jack on the back. Nothing... I have seen threads that said to leave it unplugged and battery removed for many hours, and it will work. I am going to try this and I will let you know. Good luck and please share your findings of you do find a solution.

Hi

I have a Vaio A497XP which had the same problem.

Removing the cmos battery worked for me as well.

Thanks manipulator

Tom.
