Laptop wont boot- possible water damage
Posted on 2010-01-01
I have a Lenovo U110 that was apparently affected by light water damage (carried unprotected in a snowstorm). It would not show any indication, including the battery charging indicator. The charger shows 19+V, but no other sign of life with battery or charger. I removed all components and immersed them in isopropyl achohol, and dried them carefully. I reconnected everything, still no life. Then tried with just the display, keyboard/touchpad, and DRAM and power switch cables, & CMOS battery (which is OK) but still nothing. I get life (3+V) on the power switch, which goes to ground when the switch is pressed. Disk drive is OK with external attachment.
I would appreciate any ideas for further diagnosis...
