Dell laptop does not switch to battery power

The battery gets charged ( I've switched between 2 batteries to cehck the same). When I check through the Power Meter, it shows me how much charge is remaining on the battery. But the moment AC power goes, the laptop switches off. Local laptop repair guy doesnt want to touch it since it's too old (!). Machine is otherwise in excellent shape, so I do not want to discard it.

It sounds like defective motherboard. If your laptop is more than six years old, it is not worth to repair.

Instructions

1
Determine if the laptop battery is defective. While less than 1 percent of batteries are defective, the possibility is still there. If the battery is new and only charges some of the way, it may just require a BIOS update to charge fully. New batteries that refuse to charge at all may be defective. Purchase a new laptop battery to replace the defective one.

2
Test the laptop power adapter to see if it's faulty. Run the laptop directly from the laptop power adapter and without the battery. If the laptop does not work with the adapter plugged in, the adapter is dead and you will need to replace it. The laptop battery may refuse to charge if the adapter is faulty. Charge the battery with the laptop turned off.

3
Insert the laptop battery into another laptop to test it. If the laptop battery charges in another laptop, the laptop's motherboard may be bad. Replacing a motherboard in a computer can be very expensive. If the cost to fix the computer is not worth the cost of replacing the motherboard, consider purchasing a new laptop.

4
Reinstall the battery to ensure all connectors latch properly. The latch mechanism that holds the laptop battery should click into place. If the latch does not close, remove the battery and examine the compartment for signs of damage.

5
Troubleshoot the BIOS to determine if there is a hardware problem. Turn on the laptop and immediately enter BIOS setup by holding down the "Del" and "F1" or "F2" keys, depending on the make and model of the laptop. When the BIOS screen appears, see how long it takes for the battery to charge down. If the battery does not last as long as the BIOS setup, a hardware failure may be the problem.

No battery is detected in dell 830


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Start with pulling the battery and power, then hold the power button in for about 30-40 seconds. Then plug the power back in (still no battery). Try to power up the computer. If it boots, shut it down and put the battery in and try again. If it boots the issue was cleared. If it boots with the power cord but not with the battery added, you have a battery issue.

Hope this helps

  • two ways to charge the battery:
    • while the laptop is on
    • while using the laptop with a power cord, but it will take charging time when you are using the computer.
  • --if the problem persist, the battery may have a problem, called dell technical support and have the battery serial number for possible battery recall. or replacement

Battery problem-plugged in, not charging. Lenovo 3000 N100.Type:0768.Model:24U.S.no:L3LA215. Please offer a solution.


Had the same problem with a manufactured refurb, would go to 79 %, if you go to power options, change plan settings, change advance power settings, then to the Lenovo energy management tab, press the big enable Lenovo energy management, click on the blue gear to the left of the question mark, if "Optimize for Battery lifespan" is selected it will only charge the battery to 80%, change this to "Optimize for Battery Runtime" and it will charge to 100%

Laptop compaq presario f500,running vista.Wireless is not working,Windows cannot load the drivers required for this device. (Code 31)

I experienced this problem last night, and seemed to have fixed it this morning.

SYMPTOMS: HP Pavilion dv9000, Win Vista x64 Ultimate. Running on battery, battery level became critical; windows went into 'Hibernate' mode. Upon plugging in to mains power, and resuming the Windows session, the Wireless is still disabled, no matter what position the switch is in.


POSSIBLE CAUSE: Critical battery switches off the wireless network card to preserve power. Motherboard seems to log this status but when re-connecting to mains power the card does not receive power again. Uninstalling the driver and getting Windows to re-install automatically upon re-boot does not work.


SOLUTION: Charge up the battery whilst the computer is running. You can charge it to a substantial level, say, above 25%. Disconnect mains power so that your laptop is running on battery only. Set your wireless switch to OFF (this is usually to the left position, away from the orange indicator). Now run your computer down to the critical battery level again (perhaps overnight). In the morning when you press the power button, the 'CHARGE' indicator (looks like a lightning bolt) on the front of the laptop should flash quickly, indicating that there is no charge in the battery. Remove the battery from the laptop's underside. Wait a couple of seconds, then press and hold the power button for 30 seconds. Keeping the battery off the laptop, reconnect mains power. Boot up your PC. When at the Windows desktop and all your startup programs have finished loading, switch your wireless on (to the right position). You should now have a blue light, and wireless should once again be working. You can now re-insert your battery. You might have to setup your wireless network connection again as mine seemed to be 'lost', but at least hopefully the main problem is now fixed.

The PC suppose to still be on warranty, so you can go and returned. When you bougth it, you need to charged it for a period of 12 hours. If the battery charging icons indicates that is charging, maybe the laptop terminals are not working and you need to take it to the store for that.
