First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

let it sit in the charger for 1hour then try to turn on your phone. it could be that the charger cannot charge the battery and turn on the phone at the same time and the battery is too weak to turn it on and needs a better charge.

r u mention for battery light?if is it true,then the light is blinking because of your laptop want to make sure the power supply charge that battery.if it is in charging condition,the light on.but if the light goes off,that mean, the battery is already full.

But when u use adaptor without battery, the light will goes off because no charging session is in progress which has same behaviour with battery full(during battery full,no charging session occur)

Battery won't charge


If the battery is not charging, then the charging circuit of the motherboard is bad.

Page 3-22 lists the spare part number for the motherboard. (4 versions depending on options)

It could be that your battery is defective/worn out. If the computer just shuts off immediately (doesnt try to hibernate/standby) then you're likely looking at replacing the battery. They can suddenly do things like this if a cell shorts out in the battery or due to common wear. But first, here are a couple of things you can try.

1. Try reseating the battery (pull it out and put it back in). Sometimes something that simple can fix the problem.
2. Try to calibrate the battery. Your computer may come with instructions on how to do this, but if not you can do it manually. Turn the computer on but go into BIOS (press F10 at the compaq logo screen). Don't load your operating system
Unplug your computer. If it turns off at this point, your battery is already toasted. Replace it.
If the computer keeps running, let it go until it finally shuts off due to battery drain. Then plug it back in and let it recharge completely. This will let the microchip in the battery learn its charge potential and may allow you to get more life out of it.

Note: Calibrating these batteries is good practice but it shouldn't be done very often. If your calibration doesn't work after 1 or 2 tries, you probably still are looking at a dead battery.

Laptop won't stay on


it might as well be a internal problem related to power or loose contacts with RAM or the power chords internally.
Better to go to the technician in this case.
Your first Battery would have been fine too..

Less then 5 minutes runtime at minimal load


You gave no reasons why you thought it was simply a software setting, so I gave you a link below for some management software. The HP R3000 UPS supports HP Power Management Software (CPM) version 1.8. http://h18004.www1.hp.com/products/servers/proliantstorage/power-protection/software/legacy-software.html In addition the HP R3000 UPS also supports the LanSafe III management software (discontinued). My first question is: When were the batteries last changed? If they haven't been changed in 3 or so years, then it's probably low batteries, meaning they are old and cannot take a charge anymore.
