Power Supply

The original battery pack was probably 12V, 1700mAh, but it was missing in my laptop. The replacement battery can still be purchased by the product code P170AE-10LX. I did not buy it, it was too expensive for this crap computer. In the absence of the battery pack, the computer can be started with external 12V power supply connected directly to the battery terminals at the laptop.

The original BIOS battery is AA-size 3.6V Lithium battery. It can be easily replaced with popular 1/2AA size 3.6V LiSOCl2 batteries.

The power supply is pretty unusual and hard to replace. The pinout is described on the picture below. My laptop had the capacitors on the power supply board leaked. This caused the voltage to the LCD screen go out of the original range and turning the contrast wheel to the maximum contrast level provided voltage that actually killed the portions of the LCD panel – hence the dark vertical line on it.
