Hi Dave,? Look for a 47uf/ 35V radial capacitor on a "daughter board" that is on the board closest to the rear of the 8935. That is usually the problem. A good test to see if that's the problem is to

I posted this in another group and it was suggested I post it here. I have a HP 8935 that I’ve used for a while with no issues. Turned it on recently and it shows no signs of life - nothing. I’ve

Hi Alex, ?? The lithium battery only saves screen setups. It will not save the "last settings..." Regarding the PCMCIA cards, if you are only using SRAM (battery backed up) cards, the Adtron
