Compaq presario V2000 motherboard power supply chip identification

My wife inadvertently tried to plug in a printer cable to the ethernet plug and burned up the 8 pin DIP chip next to the power in socket of the power supply. The damage defaced the chip so I can not identify its numbers. Can anyone tell me what chip to buy? The chip is designated PQ44 on the board. Also, is there any outlet for a parts identifier for this older board? Thanks, Charles

The srceen stays black


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp

Receiving Charge will not turn on


Take out the battery and only have the ac adaptor hooked up to the laptop and then try to turn it on.

If that doesn't work, then the motherboard is faulty. Probably a short in the motherboard but the whole thing would need to be replaced.

Also make sure your using the correct adaptor as well.

No power to my compaq presario


If the power adapter is working fine and tried in another laptop, then the most likely cause is the connector in the laptop is damaged or come loose on the motherboard and will need soldering to secure the connections.

If the power supply is faulty it could be the output power lead is broken inside the cable usually near to the round plug at the end of the wire so would need replacing, but beware some power supplies are made not to come apart, and be careful. You might just as well buy a new power supply if you don't know what your doing.

If the power supply is fine and the laptop shows some sign of life then the most likely causes are the cpu is blown, or the mothebard has blown, you could try taking out the cdrom and floppy drives because if one of them is faulty it could prevent powe rup.

Compaq Presario v2000 Notebook problem


Hi, Take out the battery and plug in only the power adapter and see if it comes on. If it does then leave out the battery for about 15 minutes and then put it back in. Good luck!
