Dell Laptop repair question....

Hi all, I have a Dell Inspiron 1150 laptop computer. One of my cute kids dumped a bottle of water on the poor thing, it was on at the time. I shut it down right away and pulled the battery. I opened up the case, blotted up the water, cleaned it up with some alcohol (semiconductor grade isopropyl from a fresh container) and gently blew it dry with a warm air gun. Whe I put it back together and put the battery in, it booted up and seemed OK. Of course once the battery got low I plugged in the charger. When I did so, the "AC power" LED and the "Charge" LED light but flicker on and off rapidly, and the charger makes the sort of "ticking" noise that suggests that it is being overloaded. The battery does not recharge.

Bummer.

Obviously something in the charge control stuff got wacked, but I have no idea how to go about locating what or where. If I can locate the bad stuff, I'm quite sure I could change them even if they are small SMT stuff. Besides, at this point, I have little to lose. Any ideas how one could approach troubleshooting this?

The other last ditch option is to power it directly up via the battery slot. Then at least I could call it a "compact desktop" computer or something like that. The battery pack is 14.8V and connects via

9 "blades" in the computer. I assume that there are multiple positive and negative blades. Anyone know what the pinout of these are?

Thanks for any thoughts.

Best regards, AL

At least Dell makes available their service manual for the 1150:

That's not exactly what I would call a "service manual". :)

Well, not really, but is somewhat better than nothing. Gives a few "how to take it apart" guidelines, for what that is worth.

Take what you can get, I guess. :)

Have you checked ebay for a replacement motherboard? I know there are always a variety of dell motherboards and parts offered.
