Hp 25c falure - alsaudio - 07-19-2004 Hi, recently while doing some work one evening with my 25c, I clicked the enter button, and instead of an expected result, the machine locked up. Upon turning it off , and then on, the the result is all zero's on the display which blank out when any key is pressed, or occasionaly, an "error" message. Since, I have removed batteries, had it on the charger, and any other tricks I could think of, but it seems to me it's time may have come.
I wonder if anyone could shed some light on this? I am assuming the worst. Re: Hp 25c falure - David Smith - 07-20-2004 A display of 000000000 is almost always a bad ACT chip (the big wide one at the bottom of the circuit board). ACT chips from a 21/25/29C/67/97 (but not a 27) will work in the 25C.
