Battery charges and quits


G

Guest

I have Windows XP Professional 64 running on a Compaq Presario R3000.
The battery will charge to full charge when the computer is shut down.
When the computer is running, the battery charges and then quits charging
until the power adapter is unplugged at the computer and reconnected. The
battery charges again for about 5 or 10 seconds before quitting. The battery
is new. I have tried repairing XP with the recovery disc. I have tried all
of the power options.

What can I do?

This is not software (Windows). Since you know the battery is new, the
cause could be 1) the power adapter; or 2) the charger component on the
motherboard; or 3) both. Contact HP tech support for repair/replacement.

Perhaps the battery is at full charge when the charger shuts down? The
battery is not used when the computer is plugged in.
Give details of low battery indications, shutdowns problems etc.

check the hp/compaq site for updates for your laptop. In particular see
if there is a bios update, AND that its change-log says it may fix a
battery issue; if not you may want to forgo it if everything else is fine.

I had a toshiba with battery charging issues, and a bios update fixed it
all up; apparently the older bios could not ID the battery properly, so it
wasn't controlling the charging circuit right, but the new bios accurately
recognized the battery model and it worked great thereafter.

Good Luck

That is NOT a software problem. It's a hardware problem.

I have since found that it is a battery problem. I reinstalled my old
battery, and the charging problem does not occur (the old battery does not
run the computer very long).

This raises a new question: Is the new battery compatible with my computer?
The new battery is rated for the r3000 and r5000 series. It has a 6.6 AHr
rating, whereas the old battery has a 6.0 AHr rating. Will a BIOS upgrade
from F.34 to F.35 make the new battery compatible, or is the new battery
defective?

I purchased the new battery from HP in August and it worked OK for about a
month until it exhibited the charging symptoms.

In an attempt to solve my battery charging problem, I tried to update the
BIOS with a download from HP. The executable seemed to work, proceeding
through a series of steps to FLASH. After a few seconds, the computer shut
down. When I rebooted, the BIOS version was the same (F.34). I tried the
procedure again, with the same results.

I haven't been following this thread, but:

Yes, as long as the voltages are identical. 6.0 to 6.6 AHr is nothing but
how long the battery can provide full power for one hour. One can provide
6.0 Amps, the other 6.6 Amps; no big deal.
NO. This has absolutely nothing to do with your BIOS.

The new battery is either defective (most likely), the wrong voltage,
doesn't connect properly or has some other physical defect. Return it and
get another one. Bad batteries are not that unusual, especially if they've
had them layhing in stock for long periods of time.
I assume you DID read the papers that came with it, right?
