laptop not turning on

Tarek

hello
i have an HP pavillon dv6 that someone spilled coffee on it .
I turned of directly , opened it all and cleaned it with lil bit of alcohol .
now it doesnt turn on at all , when i plug the charger , the led ( charging sign turn on ) but nothing else than that
the Hdd is working , i tried using the laptop without the battery only with the charger but nothing changed .
it doesnt turn on at all , no led lighting , no fan turning on , nothing .
thank you

When a laptop doesn't turn on, it usually means the components are not 100% dry yet, or you didn't connect everything right. Disassemble it and reassemble it again. Make sure the CPU lock is in position (I always forget to double check that. It's a real pain).
Also, try to reseat RAM, as well. Something they tend to hate you and not fit into their place correctly :P

Take all the core apart, RAM, battery, and HDD (the easy parts anyway), and leave them to dry and discharge for at least 8 hours, overnight would be fine. Also, if you could get access to the board itself, use the circuit gleaning spray on it. Liquid might dry out but still be there and short-circuit it.

That's what was happening with a board AvoK95 recently fixed. It was still wet somewhere in the chipset.

Don't forget to check the CPU lock.

i didn't remove the cpu in the first place , should i ?!

you should have stripped the board completely and washed with alcohol and use a toothbrush to scrub everything,and then use a hair dryer without heat to evaporate it all. (You should also de-solder the CMOS battery if it's soldered directly onto the board)
Then you do another round of blowing by focusing on the chips so that there won't be any alcohol left under them. Then you leave it under the sun for an hour or two (Not necessary but recommended). Then put everything back together. Please! oh Please!! follow a guide when taking apart a laptop. There shouldn't be a single screw left over after you finish rebuilding it. PM me the laptop model number and I'll send you a disassembly and reassembly guide to help you out. HP's are really tricky to take apart.

thank you avo , it is an hp pavillon dv6 .
do not worry i got it under control , removed everything , cleaned with benzin for the board and let it dry in the sun

Use alcohol. Never benzine!

ok done :D

This helped me when my computer wouldn't turn on - Not sure if it will work in your case, but worth a try:

Take the battery out. Disconnect the AC adapter from the machine. Press and hold the power button to discharge any stored power (take about 15 seconds).
Leaving the battery out, connect the AC adapter and try to boot the machine.
Also, consider re-seating the RAM.

When something gets spilled. You have to take everything out and clean it.

how much time should i wait for it to dry ? a day ?

Did you use alcohol ? If yes, blow dry it without heat and then blow it in certain places like under chips. Then blow on the very lowest heat level. Leave it for an hour or two and you're good.

It is working fine now.thank you guys
