Dear friends

I have a Laptop Sony Vaio Model No: PCG-V505GP

Recently when I plugged the adaptor it won’t on at all.
Without any charging or any others lights, no sound at all.

1)I’ve tried to hold the switch for few seconds still the same.

2)Removing the Keyboard & pull out the white socket of BIOS cell re-plug it in.
Nothing happen.

3)Opened up the laptop checked the power cord socket inside nothing is loose either.
Computer was in v.good condition.

4)Plugged the laptop all over night wait till next day but no hope too.

I have no idea what shall I do now.

But I’ve taken out the hard drive from this computer since this issue occurred,

Above all testings were done with no hard drive inside.

Although laptop hard drive was taken out at least the bios should start or lights should come up for
the battery charging.

Hope someone can guide me. thanks

Might be your power supply, your video card.

I would begin with the basics and check the power adapter. Most power adapters provide power to the laptop along with charging the battery. I would also suggest wiggling the power plug connector when it's plugged into the laptop to see if any lights turn on while your pressing the power button. Alot of power problems are related to the power plug jack on the motherboard.

is your power button bad?

that was my problem and after a $400 repair the guy said "oh and by the way you've got a bad power button." >_<

I would tell you how cheap my computer is, but the nitrogen cooling for the 3.8ghz quad-core does get pretty expensive after a while

I did same thing wiggling the power plug too but no lights.


I am not sure if the power button bad or not.
But I think even if the power button issue
It does not effect charging the battery.

Yesterday I did called up Sony repairing centre

they said bios cell will not cause this problem.

But the charges for just inspecting the maachine are too expensive.

If I attach the battery or if the bios battery is charged, laptop won't start-up with ac adapter attached. If I remove battery and disconnect bios battery, unit starts up fine??
