MacBook wont run from battery

When I remove the battery from my MacBook the computer immediately shuts down, I notice the battery says its fully charged by the 4 lights on the back of the battery but the icon on the battery in the menu bar has an x in it. I tried swapping my battery with my wife's (same model MacBook) but it doesnt fix the problem. Any suggestions welcomed.

Re: MacBook wont run from battery

Apple does have a battery recall/fixing procedure on certain macbooks and macbook pros.

The battery of a MacBook or MacBook Pro computer may:

  • Appear to have no charge (zero percent)
  • Be unable to power the computer by itself; the computer might work only when it is connected to the MagSafe power adaptor, which only shows a green LED
  • Appear with a black "X" icon on the menu bar

  1. Shut down, then remove and reinstall the battery. Test for the issue(s) again.
  2. Connect the MagSafe power adaptor (if you haven't already) and see if the behavior continues.
  3. If the issue(s) persist, download and install the Mac OS X 10.4.9 Update.
  4. If the issue(s) persist, Download and install Battery Update 1.2.
If, after installing the Mac OS X 10.4.9 Update and Battery Update 1.2, a black "X" still appears in the menu bar, contact apple by calling 1-800-MY-APPLE (1-800-692-7753)

hold down F8 when it powers up. May need to remove battery and power cord. New windows 8 and probably windows 10 do not fully power down usually you have to hold shift key when shutting down windows from operating system. So it may not go into safe mode without it being shut down fully.

Presario R4000 battery is charging but the lightning bolt is not lit

When you first turn on the laptop, does the lightning bolt LED light up for a split second, even before Windows opens? That is a test that the LED is not burned out. If it does, then are you using the correct AC adapter that came with the laptop? Some look identical, but are not as powerful enough to run the computer correctly and you wouldn't necessarily notice a difference except something like the LED. How old it the battery and how long does it take to fully charge?
1. Reset the laptop by shutting down the laptop and unplugging from AC power;
2. Remove the battery;
3. With the computer unplugged and no battery, hold down the power button for 30 seconds. Remember no power on the computer at all for this step.
4. Replace the battery and plug it back in and turn on.

If that doesn't help, search the internet or HP's web site and update the BIOS for your specific system. Look for good directions for doing this and don't run the BIOS update from the internet, you should download the BIOS to your computer and then run it from there. The BIOS cannot be interrupted. If the BIOS is interrupted while installing, it WILL render your computer useless and you will have to replace the motherboard (extremely expensive).

Battery was fully charged on my hp nc6400 i shut it down and sat it aside, i noticed the battery light contuniously flashing, i hit power and nothing happens.

Dead battery, how old is the battery, Is it a replacement? Do you remove it when on AC for a long time? Test battery, replace if necessary. I never leave the battery in if I am on AC, say at home, and NEVER leave a laptop unattended and plug in with battery in when not in use. A faulty battery is a possible fire hazzard.

My Toshiba nb505 netbook run with the AC adapter, but will not run on the battery. The battery shows that it is charging but the charging percentage does not increase. Any advice?

I own the Toshiba NB505 netbook and the very same thing was happening to me. Here is what I did to fix my issue:
Step 1: Shut down the computer and remove the battery. Then turn it on but now with the battery out. It should say "battery not detected".
Step 2: Open control panel and open the "device manager". Under "batteries" (the first one), uninstall the one that says "Microsoft ACPI Compliant Control Method Battery". This is the battery driver.
(Don't worry. The computer will automatically re-install it)
Uninstall the driver and shut down the computer.
Then reinsert the battery and power on the computer. The driver should have re-installed itself. Check to see if the battery is now charging.
(It will take awhile for it to fully charge to 100% Best to shut it down and let it charge. The far left indicator light on the front of the Netbook will turn green when it is fully charged)
Hope this helps. Yeah I had to figure this one out on my own. Toshiba support staff over the phone were useless!
Good luck!!

New battery HP g61 is fully charged but not working \

Maybe the AC Adapter Power Cord is not working. If you can't get on the laptop with the power cord then it is bad and the battery might be drained so you have no power source to power up the laptop.
If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

HP Pavilion dv7 Problem.

your laptop is hard wired to shut down when the input is to high into this port. You more than like have a damaged AC/DC converter box in the line (the little box on in the middle of the power cord). This handy little thing converts your powerful and destructive AC current to a DC range that is compatible with the delicate circuits of your system. I would recommend refraining from plugging this system in until the cable has been replaced as you may soon encounter catastrophic failure of key components. HERE is a link to heck out a few online purchase options.

Computer immediately shuts down upon starting had the computer on earlier today shut down in stand-by mode. later I tried to restart the computer and once it got to the main screen with the icons shown it...

Ok Take out the battery and leave it out for about an hour. IN the time its out Run the laptop on AC power and then go to control panel, open power options, and remove the hibernation check, and the turn the system standby to never, then hit apply. Then turn you laptop off and re insert the battery. If you still get the shutdown where it wont run on battery, then you need to replace the battery.

Battery appears charged, but computer will only run when plugged in

does your battery have one of those charge indicator panels on bottom?

also, it's possible that the connection from battery to the internals is shot..if that's the case, then you're looking at a major motherboard swap

Randomly shutting down

Hi katrina1331, From what you describe it could be a couple of things but the two the come to mind first are power and perhaps overheating. The fact that you can?t run on battery power very long would suggest it can?t hold a charge or much of one or the AC power adaptor or charging circuitry aren't working correctly. To proceed I need to get some more information from you: Are the A/C adaptor and the battery the original ones and how old is the laptop? There are several LEDs on your laptop, (we?re going to ignore the touchpad light and the wireless LED), a power/standby LED to the top left of the keyboard three just below the touchpad. The left LED is another power/standby LED, the hard drive LED in the center and the battery LED on the right. -What are they doing just before the shutdown and immediately after while running on A/C power? -What are they doing just before the shutdown and immediately after while running on battery power? Try running the laptop with the battery removed and the A/C adaptor plugged in. Do you notice any change in running time? With the battery and A/C power plugged in click on Start, Settings and then Control Panel. Find and double left click on power options. A box labeled Power Options Properties will open, click on the tab labeled Power Meter. It should indicate the battery is at 100% or that the battery is at some percentage and that it is charging and running off A/C power. Let us know what you find. When you first start up the computer run your hand along the bottom of the laptop, especially along the four screened vent areas, to roughly gauge the laptops temperature. Use the laptop in a way that causes it to turn off and then run your hand along the bottom surface again. If the laptop is hot, to the point where it is uncomfortable to touch, then overheating may be a factor. Let us know what you find out and we?ll continue.
