Question about HP Computers & Internet
I plug in the power supply and all I get is a flashiing charge light and a flashing power switch light. If the battery is charged it will come on but the battery doesnot charge with the power cord in the system.. Changed power supply to a known good one same thing.. some one said there is an eight prong chip on the mother board that regulates the chargeing voltage s and AP Something or Other.. Do you know what I'm talking about.

You have a ground fault issue in the DC JACK.
There are escentially 4 circuits in the jack and one is not making contact.
1: Negative Charge circuit (outter ring)
2: Negative Run circuit (outter ring)
3 Positive (Inner Ring)
4: Signal (center pin)
I believe the negative charge circuit (outter ring) is not making contact internally. Typically what happens on that model DC Jack is the tension contact metal becomes fatigued, and does not touch the outter ring.
This could come from Heat causing early fatigue of the metal.
Or normal wear, the metal has simply worn out from regular insert/removal.

This unit had a RED CHARGE error. Replaced PQ38 solved the problem.
If you get an error on the charge circuit after replacing the PQ38 you should also replace PQ38 because it too may be blown. Make sure Pin 1 where the dots. Also check the MOSFET on the other side of the COIL too.

I agree. Batteries have a limited life. Also--once you have a new battery installed, be sure you let it discharge all the way (until the computer tells you it has to be charged--about 3% remaining) at least once a month. This will ensure you get the maximum life out of a battery.
