Ac power pack keeps failing, wont charge battery

It sounds like the Battery is Dead or not charging. You might try a local pc shop and see if they have any laptop batteries for you laptop. Or have them test to see if the battery is charging.

Try to update bios n check it out..

Take the Battery back Its defective , New batteries should charge for 18-24 hours, and the computer should tell u that it wont run till the battery is fully charged.

It's sounding like a motherboard problem to me.
You've done all you can--the circuit on your motherboard that controls the charging is evidently gone bad on you.

start wit ha power reset, remove the battery, remove the ac adapter, hold the power button for 1 minute and then repalce the battery and ac adapter, if theres no go try it with just the ac adapter, sometimes the batteries short out. if all else fails its probably the mmobo and i suggest calling compaq for warranty support

you may need to have that battery charge for a while, until it can be seen at charge level..or simply check the connections to see that there is no junk in the connector..

Page 205 should answer your question.

My guess since the battery checked fine in another laptop would indeed be the charging board or charging circuit on the motherboard.

hi!

i'd say first try a known working ac adapter and if that Working AC adapter works and the system detects the battery well, then it could be the ac. If not then try to borrow a working battery to get your final conclusion. if the working battery still doesnt work properly, then it could be the system motherboard. If battery and ac adapter (working) are not available, then check the BIOS and see if it really doesnt detect the battery. try flashing the BIOS and still if that fails, then replace the battery.

hope this helps!

use ebay, same thing but cheaper in prices... i got my presario v2000 ac power charger for 24.50 with shipping and handling.... took 3 days and it arrived unless u want to do overnight shipping which is like an extra 12 bucks which is good too... WELL WORTH IT EBAY IS THE PLACE... i think his name is "honestworks" or something like that buy it from him he has a one year warranty if any defects occur...
