My IBM T40 has got a liquid spillage on the keyboard while was operating !! , when I left it for some time then tried again, it powered up normally & worked very fine But once it turned off , it...

Once the liquid was spilled it was important to open and do a full clean up on the board. Now it seems there is moisture or shorting in the board due to this which can cause this malfunction.
So it is best to remove the keypad and check on the mother board. Clean the board and dry using a hair dryer. Make sure that the keyboard also is fully dry .
Reset only after the board is fully found to be dry . If the set wont power ON then some damge was done when it was powered the last time due to the spillover shorting.

I need a new mother board my mother board was

The first thing when spilling drink on your electronics is to remove ALL power.

Then wash the circuits with DISTILLED, de-ioniozed water till all traces of the spillage is gone. Next driop dry with one corner down and finally let dry a few days.

The only damage the spillage usually can do is electrolysis from the power source. Circuit boards are washed with water during manufacturing. Use DE_IONIZED !!!

Compaq V2710us shuts down randomly with a loud click

Loud click sounds like either a short or overload, causing ground default. recheck inside for any loose connections anything grounding out the motherboard.

Mother board

The motherboard is bad, you can try taking out the battery and only hooking up the Ac Adaptor to see if the problem goes away but if it doesn't then the motherboard they replaced it with is faulty.

Actually since water was spilled on it beforehand. Take out the hard drive and dvd drive and try powering it up again just to rule out the hard drive or dvd drive shorting out the computer.

Wont boot no bios screen nothing

Check your memory card. Reseat or clean its edge connector with soft eraser.Do this after you shut it down properly , battery disconnected, and no any other power source is connected.

That is the first thing to suspect. Or try it also with a spare good ram card.
