Question about HP Compaq Presario 2500 HP Pavilion ZE 5000 NX9010 Series (chassis bottom)319470-001 (319470001) CD-ROM Drive
About two years ago the AC adapter supplied with my HP Compaq Presario 2500 (2596US) malfunctioned, and I bought an after-market adapter with multiple connectors for different computers. I have been using it since without problems. Now, on occasion, the connector seems to lose its connection and the unit switches to battery power. This can happen even when the unit is sitting on my desk unused. Most times I can unplug the adapter and plug it back in (sometimes it takes multiple tries) and it will start to work again. I'm starting to suspect that the socket in the computer is actually at fault rather than the adapter itself. The connections does not feel as tight as I think it should. Is the solution to replace the socket, and how difficult is that for a non-techy, but otherwise competent person?
Why not buy the correct power pack
matching the power needs of you puter.
each puter needs a watts level, do that or more never less.
only hp.com spec tells you what you need,
its in the service guide for you PC.
take out the battery
now run OFF LINE pack
run now? good, does it drop dead if you gently
wiggle the plug at PC port> not moving pack and its cable.
yes, then the PC has a bad power port end cause.
if it is the PC power jack bad
you will never fix it. its real deep and takes totally disassembly to reach.,(done many and do no teach LT guts to anyone)
amazing HP.com has your books, and is always there.
read them it specs it out.
yes, power packs go bad, 3 ways, dead, weak, or intermittent.
all do in time, (max life is about 20years,less if overloaded, as i bet you did)
if the PC needs, 50w, do not put in a 30w. use 50 or 75 or 100w
see? or it overheats .the pack,
here is your page (OP)
seems very very old, HP, is fighting me...
needs 19v at 90watts,
$8 to learn what is bad, is this too much>?
old XP LT built in the 1990 its very very old and slow.
256mb ram wow. Celeron ouch.

I used to have these same problems. I replace my BIOS battery, which I know was dead, because all settings get reset when I unplug the power and remove main battery. You might not have to replace it if its still good. Back to the main battery problem, You have a good change of solving this by going into BIOS, and under Tools there is a Battery Calibration option. Do the calibration for the main battery and-or other optional batteries attach and it will most likely solve the problems. This calibration process will take a long time; 1-charge, 2-discharge, 3-recharge, so leave it over night or however.
There was a mention of updating BIOS. This could solve the problem too, because BIOS controls the charging unit. Also, make sure you have Compaq Power Management install on your OS, (download at hp.com).
One note: it will not charge if the battery is about 93% or higher. 93 is not exact, but close to 90%. so test by discharging to below 90% and it will start charging again.
If anyone tries this, leave a post of your success or failure.

It sounds like there is a problem with your motherboard. You would have to take it someplace to run diagnostics on it. It may be time for a new laptop

I have a DV1130us and I'm having the same problem. I've already replaced 2 blown SMD capacitor on the motherboard, originally would only short out and obviously not boot or charge.
But I think it may be the MAX1907a chip, basically the actual power supply controller for the laptop, though it may also just be another bad cap somewhere. If/when I get mine working I will post what I did to get it to charge.

For all those with the ZV series power jack problem, I have replaced a few of these jacks and it is not an easy job unless you are an engineer.
The entire laptop needs to be disassembled, all the panels need to be removed, including the keyboard and you almost have to remove the motheboard.
Even when you eventually gain access to the offending part, you will need to be competent in using a soldering iron to remove the jack without damaging the printed board, then clear the holes so the new jack can be fitted.
While you are doing all this, you need to remember that the circuitry is static sensitive. This means that you can kill your motherboard just by touching it.
When you have finally finished the job, unless you have been pretty smart, you'll end up with a box full of different size screws and you won't know what goes where!
With the ZVs I have repaired, I usually supply a short jumper lead that plugs into the power jack on the back of the laptop. This is two or three inches long with a cable power socket on one end and a power plug on the other. This means that the user can leave the power plug plugged into the laptop all the time and just disconnect and reconnect the power unit from the other end of the patch lead instead of wearing out the laptop's power jack.
