Battery fully charged, can't power on

HI, I have a Sony Vaio laptop ans as of 2 days ago, I can't power on when on battery even though it's fully charged.
Nothing happens when pressing power button. 
Can only power on when plugged in. 
If I unplug power cord, laptop completely shuts down.

Hi,

Check with Sony Support, their on-line documentation, diagnostics, and ask in their forums about
any known issues.
Or check with a real computer shop (one that does in-house service on Sony
and not leeks and peeks at a Best Buy or other Big Box Stores).

More help and information which might apply :

The battery may be worn and need to be replaced, the battey contacts could need to be cleaned (if

they  can be), or there could be other hardware or software issues.
Check with a real computer shop

(one that does its own in-house servicing) or Sony's Support.

-----------------------------------------------------
References to Vista also apply to Windows 7.
Check with System maker's Support, their on-line documentation and drivers, and their forums
(if any) for known issues.
Some maker's have issued BIOS and other updates to help with battery
problems.

Other information that might help :

Control Panel - Power Options - Power Plans - Change plan Settings - check the Advanced
Settings for drain and usage settings (this is how much to be used and not how much or how
long to charge).
Actually what causes a lot of wear on a battery is draining it too low repeatedly.
With today's
systems over-charging is not an issue.

Here are some tips to help and troubleshoot battery related issues.
Old battery? Unplug power to computer - remove battery and clean the contacts with a pencil
eraser (do not use this if your battery has thin slots - just clean the knife edges that fit into
them and be careful).
Batteries do wear out if old, or it could be a problem with the computer.
Check with the support of the system maker and many of them have on-line forums.

Newer type Litium-Ion batteries usually last longer if you do not discharge them below 30%
however on a laptop that will not extend their life that much.
Best is to use A/C adapter
whenever possible.

I use the free version of BatteryBar to monitor my battery.
Click the Green button on the
Yellow box on right side of page to download latest stable version.
