hey, i know it's not the best advice, but i think the only one who can help is your customer support. do you still have guarantee?
it seems to be a technical problem. maybe a defective contact.
I have reviewed all threads relating to this issue but did not find a match to my problem.
I have a three year old Sony Vaio and few months ago the battery went dead as in with AC power cord and battery plugged in the battery wont charge and the battery light keeps flashing regardless if the battery is in or not( on AC power.
The issue started that every time i press the power button the system wont start so after playing around with the laptop i figure that if i press the front end of the laptop ( space between power button and camera/mute button) and then press the power button a few times , its powers up.
This is the only way i can turn on the lap top now and some times its takes a good 20-30 tries , pressing different end of the laptop and power button together to make it work.
Any suggestions pl ??
