Question about Compaq Presario M2000 Notebook

New battery will not charge

I have a three-year old compaq M2000; the factory battery had steadily declined until it would hold only a few minutes' charge, so I replaced it. I plugged the computer in to charge with the new battery in place, and went to sleep. In the morning I unplugged it and turned it on, to find a low battery warning: only 24% charged. I ran it down, and plugged it in again, then left for work. Returned twelve hourse later, and still-----24%! Help?

    Yes, I'm using the adapter which came with the computer. The cable has been repaired at the end which plugs into the computer, after the wires got disconnected or shorted out through wear-and-tear. The thing is providing enough power, s far as I can tell.

    I bought a refirbished laptop and have been having trouble with the battery. I've only had it a few months and the battery came with a 30% charge. From then the battery has declined to a 20% charge. I've never been able to unplug the computer from the adapter without losing power. I recently purchased a new battery and I recieved the same results. The new battery started at a 20% charge and has not gone up at all.

It could be a Problem with Your Powerjack and may need replacing. You can diagnose this at my website: there is also a useful DVD there to show you how to open and repair a Power Jack.
Or DC Socket.

Hi, Well, first, do you have the correct ac adapter?It's possible to have an adapter that will run the system, but not provide enough juice to run the machine AND charge the battery. Did you replace the battery with a brand new one? Thanks

Cordless drill - model KC9682C - probably 8 years old. Stopped working shortly after a battery re-charge. I'm guessing it's the battery. It charges for a few minutes then the red light goes off. Could it...

If light is on charger the charge is fine. You could verify using voltmeter it should put out = to what it says on the back of charger 12-18 volts or so.
Most likely battery is shot after 8 years they just dont' hold a charge anymore and they often will only charge for a few minutes when the chip in the computer tells the charger to shut off due to defective battery.
compare prices of new drills and new batterys sometimes new drill is not much more. Try ebay and harbor freight for ultra low priced batteries.

When i boot up, my Compaq CQ20 displays the message that the battery has low storage capacity. Battery time is now down to 15 to 20 minutes at full charge.

If you laptop is more than two years old then it is possible that the battery is faulty as many of the compaq laptops have poor back up battery orr quality retained.
Check the adapter on the PC , check if the adapter charges the battery to full capcity , now if this charge wont lat more than 20 minutes , you might need a new one.
Discharge the battery fully and charge few times as the last resort.

My acer aspire 5535, amd turion x2battery runs out faster than it used to

The battery starts a slow decline over months and years, eventually you will notice the time between charges gets less and less until you are down to minutes, this quite normal for these batteries. The average life span is one to three years for most batteries before replacement is required.

My compaq presario m2000 will not hold a charge it will say that its charging but once it gets to about 36% it says it discharging

let the battery completely discharge, then fully recharge. Do this at lease two. After it has fully charge the last time, see how long it takes to disgharge. It should be somewhat better. If that does not work your battery is shot and needs replacing.

Battery does not charge

Will the old battery (that you are replacing) charge up at all? If the old battery charges but the new battery will not, then it's likely a bad replacement battery.

To rule out the possibility of a corrupted battery meter inside of windows, you may wish to leave the laptop on battery power only, until it dies. A 5% charge will usually only grant you about 20 minutes of laptop life maximum. Since you left it charging all night, you should get a few hours of life before it dies. If you get a few hours of life, the battery meter software is corrupted.

Most likely though, the replacement battery is bad.

Battery won't charge

This is true, you will not be able to charge the battery without the correct charger. For mostly all laptops, when the charger is not maintaining a charge, it is time for a new one. However, it does not have to be the manufacturer's adapter, but I recommend purchasing the battery made for the Compaq Presario M2000 Notebook. has decent deals on these adapters.

I hope this helps. Please let me know if you have any other questions.
Thank You, Raph30
