Question about HP Compaq Presario V2000 Notebook
Question with testing dc jack on my Compaq Presario V2000. I have it apart now, think I can avoid unassembly of the motherboard, fan, etc, by prying up the corner case just enough to get iron in.
It is still in circuit, no matter how I ohm it, it shows shorted with pos. & neg. dont know if I'm not doing something right or what. Battery I beleive to be dead, so could not test that to see if it powered up.
The jack is not loose, one or two joints may or may not be cold, but am curious if there is a sure fire way of testing the jack to find out for sure.
Also, how important is it for reassembly to try the power?
Thanks. Bob [email protected]
You are not supposed to get a short on the power you could take out the power socket and try the test straight to the board.
On a board I have that works using my digital meter on the diode setting I get a reading of 1200 aprox and 190 aprox when the probs are reversed.
If you have a dead short and the power socket is ok then likely there is a resister shorted out or a diode or even a transistor chip on the mainboard.
It should be ok to power up while in bits so long as the cpu fan is running.
Good luck Regards Wayne.
