Andi, brilliant. It worked. I read about the method, but a picture is worth a thousand words.

Prior to this, I inserted my new battery from eBay (the good seller), and plugged in the ac power adapter. Not what I expected. A little red dot in the upper left corner. I know the display is good because every now and then the entire display flashes stuff, almost like it is iterating through a program. But I don't get anything more.


I opened it up and took a picture and posted it here. There was some green stuff on the power strip I cleaned up. Everything else,I'm leaving till I hear back from some experts on this thread. There is no corrosive material inside, which is good.

Do I need to simply charge the battery . I'm not sure if he shipped it out charged. Without ac, the display is dead. With ac red dot and periodic flashing of lots of digits in the display.


Here Are the pictures. Titled hp34c opened Thanks all for the help so far
