Laptop battery not recognized but seems to work
From HP support:
Resolving "Battery Not Detected" Problems
Sometimes Windows does not detect the presence of a battery. This can occur even if you have a good battery. There are several things you can do to resolve this problem. HP recommends doing each of the following steps, in order, and then testing to determine if the battery is detected after performing each step.
You can test for the battery while the AC power is connected and when the computer is running on battery-only power.
Perform a hard reset.
Reset the BIOS defaults.
Update the BIOS.
Determine if the notebook starts using battery only.
Did hard reset: No change
Bios is very basic, no option to reset defaults
Bios is latest version
Notebook starts on battery only
In essence, laptop works on battery, but will not recognize battery even when diagnostics program is run, returns "No battery detected". Removed and replaced batters driver in device manager. No change.

The time is correct. Good thought, but not the answer. :-(
for testing purposes what happens if you try another battery?

My other battery will not hold a charge for more than 10 minutes. It is detected correctly. Somehow the new battery is charging, and will boot the computer. I just have no idea when/if it is charging beyond that. That's why I need the system to recognize the battery so I can check charge and amount of charge left. On the HP page it said to completely wipe the drive and reinstall from backup disks. I wasn't doing anything, so I did it. Complete wast of time.
is this an original battery? if not the message can be normal
if it is an original one, you can have a bad charging circuitry
you can try battery infoview to test it : http://www.nirsoft.net/utils/battery_information_view.html

Nice utility, thanks! Now the results, and they aren't good. All the information blanks were just that, Blank. :-( It boots up fine on the new battery,,,I'm leaving it "working" to see how long it lasts and put the results here. Never heard of a battery that didn't show up in diagnostics but still ran the pc and accepted a charge.
imo - that depends on how the manufacturer made it recognise batteries - only original, or all?
another option is a fluke in the charging circuits..
do a full charge, and note the time it takes to discharge 10% and 50 % in idle, or during a continued task, like copying the same folder over in some place (to speed up discharge)

I can't do that because there are no readouts available. That's the problem. The bios/laptop/OS whichever will not acknowledge the presence of the new battery. I get no data.
is it an original battery ?
you can do a 100% charge discharge cycle
im sure you will be able to see when it 's fully discharged

The bios/laptop/OS whichever will not acknowledge the presence of the new battery. I get no data. Nada. No indication of fully charged, fully discharged, nothing in between. All I have is the battery icon on the task bar with a red X on it and a "no battery is detected" pop-up. I do not know if the battery utility works and the battery won't respond, or if the battery is saying "hey, I'm here" and the utility is broken and doesn't get the information.
i suppose you tried all options from the hp support pages : http://h10025.www1.hp.com/ewfrf/wc/document?cc=be&lc=nl&dlc=nl&docname=c00295418
a hard reset maybe as suggested here?
http://h10025.www1.hp.com/ewfrf/wc/document?cc=be&lc=nl&dlc=nl&docname=c01702473
i know - you said that.
i still believe you'll notice when it shuts down; and it will be fully charged if left on for 24 hrs
the only other posssibility i see is do a backup, and factory reset

Performed a hard reset, and also formatted and installed "Factory Fresh". Neither made a difference. The company is replacing the battery...we'll see. I'll let you know the outcome if they leave this question up.
probably a bios, or mobo problem
ASKER
Replacement battery just showed up, not recognized either. Will take a charge...yeah, I know, thats crazy...and I am currently timing it to see how long it holds it. Results later.
ASKER
Well, that was quick enough. 4 minutes is all it lasted. What's happening?
it's not charging -imo = bad mobo circuitry
ASKER
any way to tell? diags?
well - you never answered when i asked if you tried all suggestions from the support page, so hard to tell
the only diag i know = a new battery; or test this battery in a similar notebook
you can always try nirsoft batteryview http://www.nirsoft.net/utils/battery_information_view.html

I have tried a host of suggestions from the web, all of which assured me that they would work. I have also tried all the suggestions in this thread. Nirsoft batteryview does not detect it. Spent 2 hours+ on the phone with HP support last night. Their conclusion? Take it to a a HP Certified Repair Center. It's 4 years old, not sure what I will do.
many will opt for a new laptop, if funds permit.

Getting another battery to try...
ok - let's hear the result
