hello friends i have hp 840 g7 with password i try with unlock1 but its not unlock can any friend unlock this file please... -
CPU fan is not working. I replaced the fan, it is a still a no-go.
The fan has 4 pins:
1. Ground
2. 5V
3. PWM controlled.
4. 12.6V
Pin 2 is showing always on 5V. Pin4 is showing always on 12.6V which is correct.
When running diagnostics on the CPU fan, pin 3 always stays @ 0V and the diagnostics module reports not being to find the CPU fan. I don't have the schematics for this board. I assume the PWM chip is bad but without the schematics, where can I find it?
Thanks. -
no display issue on this one.

Hello all. I'll try to keep this short. I have no knowledge of electronics. I can use a multimeter and am familiar with caps to some extent. I bought a Kenwood KR-6030 vintage stereo. It need work and so I thought I would recap the thing since I get power to the on switch but nothing else is working. No lights, no sound and so forth. I went to Mouser to order caps and I find I am way over my head. I not only do not know the type of capacitors I need but Mouser and digikey do not accept Kenwood part numbers. I have the info such as 220uF 63v and such but no place to put it. I could buy a recap...
