Http:// : step by steps.

open the side.
Look for a quarter sized silver battery on the lower end of the motherboard. It will say 3V.
There is a locking lefer to press, and it pops out.
install reverse of removal.
be sure the pc is unplugged... not just off.

HP pavilion dv1000. BIOS password It doesnt have the battery but runs off of the power supply and wall plug how do I reset it so I can use it. Bought it at a garage sale

you will have to take the CMOS battery out for awhile to let the motherboard discharge. the battery is inside the laptop on the motherboard. its a round flat silver battery. sometimes you will have to reverse the polarity and short the bios out. you can find that procedure on you tube.

Well it can't !! Try as you might, jumping the battery contacts, leaving the...

Laptop switching to battery while connected to AC adapter
Q. While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small “camera flash charging” sound, stabilizing at 19v. When charging, it repeatedly makes the “charging sound” Faulty AC adaptor? Or Faulty battery? Or Both?
A. First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It’s either broken or loose. It’s a known issue with laptops and you can fix it by replacing/resoldering the power jack or relocating it outside laptop case.
It also could be a problem with the power cord. Find a multimeter and check the AC adapter. See if the power cuts off when you jiggle the power cord. If it does, replace the adapter.
Second problem: The battery will discharge from 100% to 90% and then jump to 0%. It sounds like a bad battery.
Battery charging light is on even when power adapter is unplugged and laptop is stitched off
Q.The yellow light for battery charging does not go even after switching the laptop off and power jack is disconnected. Battery does not charge at all with power source connected.
A. First of all, try reconnection the battery if you haven’t done it already.
The battery plugs directly into the connector attached to the motherboard. If the battery charging light stay on even when the power adapter is unplugged and the laptop is switched off, it’s either bad battery or something is wrong with the motherboard. The only way to find the culprit is testing the laptop with another known good battery.
Also, you can try this. Remove the battery and plug in the power adapter. If the battery charging LED lights up even when the battery is removed, most likely you have a problem with the motherboard.
Battery charges only when the laptop is off
Q. Bought a Laptop without AC Adapter. I noticed it would charge the battery OK when the laptop was off but once in windows it would not charge the battery.
A. This is very important to choose the right AC adapter for your laptop. The output voltage MUST be exactly the same. If your laptop requires 18.5V you must use 18.5V adapter. The amperage should be the same or higher. If the laptop requires 4.74A adapter, you’ll have to find an adapter which provides 4.74A or MORE.
While using AC adapter alone or battery alone, laptop works. While using them together, I am getting a problem.
Q. While using AC adapter alone or battery alone, laptop works. However while using them together, laptop LED lights blinks and the power meter for battery drops down immediately to 0% critical level, whereas the battery LED indicator says it’s full. I tried to unplug the AC adaptor while it went down to 0%, then the power meter for the battery came back to normal 85%.
A. There could be a few different reasons why it happens:
1. It might be an issue with the BIOS. Make sure the laptop has the latest version of BIOS installed, update it if needed.
2. It might be a software related issue. If you have some kind of power management utility installed try uninstalling it and use Windows power management utility instead. Also I would try reinstalling the operating system if upgrading the BIOS or removing the power management utility does not help.
3. If you still experience the same problem even after upgrading the BIOS and reinstalling Windows, most likely you have a problem with the motherboard. Apparently the charging circuit is not working properly. I assume it’s not a problem with the battery. You’ll have to check the motherboard in this case.
Problem with my battery. 100% to about 40% the battery discharging normally then suddenly from 40% it drop directly to 2%.
Q. When I use only on battery, from 100% to about 40% the battery discharging normally (last about 1 hour) then suddenly from 40% it drop directly to 2%.
When I plug the AC cord, it won’t directly charge (the charge LED is still not on). After 10 to 20 minutes it then starts to charge the battery (the indicator say that it can be charged to 100%).
If I turn-off the laptop and then charge the battery, it won’t also directly charge but the delay is much shorter (maybe just about 1-2 minutes).
Is this the sign of a bad battery (when hot it can’t be charged?) or maybe a bad AC adapter (not enough power to charge the battery when the laptop is turned on?)
Note that this symptom is always repeating when I use the laptop.
A. From the first part of your complaint description I can see that you have a bad battery. The percentage might vary, but the process of discharging is the same – the battery discharges fine until some point and then the remaining charge suddenly drops to the minimum. You’ll have to replace the battery.
I’m not sure about the second part. Probably it’s a battery related problem too. Just in case check if there is a newer version of BIOS available for your laptop. If you find one, upgrade the BIOS.
The battery is 100% charged but it will die within a few minutes as soon as the laptop is unplugged.
Q. When I unplug the power it will run off the battery, the battery icon says it is 100% charged and I have 2+ hrs remaining, but within a few minutes I get the “critical battery level” message and it will die. When I plug it back into AC power the battery charge light comes on (and will remain on for over a hour), but I will have the same problem with it dying as soon as it is unplugged. Do I need a new battery?
A. It looks like you have a bad battery. Here are some behaviors typical for a dying laptop battery:
1. The battery charges normally (according to the battery icon) but as soon as you unplug the laptop, it dies almost momentarily.
2. The battery charges normally. When you unplug the laptop, it discharges normally until some point and after that point starts discharging very fast. For example it might take 10-15 minutes to discharge from 100% to 80% and then it discharges from 80% to 0 for 2-3 minutes.

    Will laptop work with dead cmos battery?

    Yes, but each time you start the computer you have to enter the BIOS to set the proper time and date. This is essential for certain progra,s to run correctly, when the computer shuts off, everything will be reset once more.

    I have baught a laptop from the pawn shop and it needs a password

    You'll have to reset everything in the BIOS configuration. You could check on youtube for possible support on how to open a dv1000.. remember this may void your warranty
    1. Open the computer's case
    2. Find the battery on the motherboard
    3. Remove the battery
    4. Wait a minute or so (to make sure that the m-board's compnents have powered down)
    5. Reinstall battery
    6. Close case
    7. Start the computer
    8. Go into the BIOS settings program
    9. Set up the BIOS
    Some motherboards have a jumper on the board - a jumper which, when shorted will erase the BIOS settings
