DV6000 trying to debug after spill

[aaronrafe]

Have a HP DV6748us, Spilled a drink on keyboard while it was running. Before I could unplug and take out battery, it died on its own. I opened it up and let it dry with a fan blowing on it. After a couple days and feeling that it should be dry I tried turning it back on. It started up normally, I just had to use a flashlight to see the screen and the keyboard wasnt working. I have since replaced keyboard and invertor as well as thoroughly cleaned motherboard of any remaining residue I could find. The monitor is still dim??? Any help would be appreciated

Thanks

When you say a "drink" - was it water? If it has anything with sugar in it, you will probably need to clean with alcohol - as the sugars in the beverage are going to play havoc with the system.

It may not help, but if you get 99% Isopropyl Alcohol for a cleaning agent, you can clean the components to remove all residue still inside. You can use lint free swabs to clean caked-on areas. Distilled water is the best item to "rinse" the effected areas (the alcohol is expensive - distilled water is about $1 per gallon).

If the components haven't been fried from shorting out, you can revive it. It might be residue that is creating the issues. After cleaning - make sure to let it dry out for 48 hours or more....just to be safe.

Nope your right it wasnt water it was some juice, and Rubbing Alcohol is exactly what I used to clean everything up, there wasnt much intrusion as it seemed the keyboard soaked a lot of it up. Still frustrated that everything else seems to work fine except the screen, even after the invertor swap?

The problem with spills - if the liquid comes in contact with components, it shorts them out. Depending upon what is being shorted out, it can destroy the parts. Sometimes you get lucky, and components are easily spotted that have been damaged.

If it has been thoroughly cleaned and dried, and there are still issues, there are hardware problems that must be resolved. Often very hard to determine which, if not all components that have been fried.

Hi

As said, liquids can corrode/damage the motherboard...

Laptop repair shop for diagnosis...
