"Battery being charged" indicates that this is a laptop. Auto shutting down indicates that you are having issues with the power supply/brick. One thing to try is another known good power brick. Otherwise it is likely your power inverter inside the laptop.

Sure sounds like powerline troubles. Be aware that fixing these kinds of problems are risky, so be careful and know you might trash it by accident by following the suggestions below.

Remove the battery completely throughout all testing.

First check and make sure the powerpack is outputting the right voltage, if not, you have a bad power supply. If that's okay, and you can get it to boot up at all, trying twisting the body of the laptop lightly, jus a little, diagonally. If the laptop shuts down or locks up, you have a motherboard problem or bad cabling somewhere.

My opinion only: from the description it sounds like you have a power short on the motherboard where it contacts some part of the case. Try removing all screws on the underside of the case and rebooting. If this does not work, unplug it and try to loosen the motherboard mounts slightly by removing the retaining screws and the ones that hold the keyboard assembly in. Then try to start it up again. I would guess that at some point it will start up and work normally, and from there you need to try to identify where the problem is. I have fixed this type of problem before by lightly insulating the separate component boards from eachother and the case contacts with spacers made of double sided foam sticky tape, and reassembling. This is just a guess, but was what went wrong with my Toshiba Portege.

Good luck...

PS: If the laptop has any add-in cards like a network card, remove them before testing

SOURCE: The laptop won't boot/turn on, no noise

Try this:

Remove all connectors, media and devices (cables, USB devices, floppies, CDs etc)

1. Press AND hold the power button for 10 seconds. Light should go out.

2. Remove battery.

3. Plug in PSU (the AC power supply unit)

4. Press power button.

5. If the laptop starts, go all the way to desktop and run the laptop for 20 minutes or so.

6. Shut down and remove PSU.

7. Re-attach PSU and then insert battery.

8. start laptop. If it starts, go all the way to desktop and use laptop for an hour or so, to monitor the battery state, see if it is charging. If it is, go to step 9. If not, test PSU and battery, to see which needs replacement.

9. Otherwise open START MENU/SETTINGS/CONTROL PANEL/POWER SETTINGS.

10. Uncheck HIBERNATION in the tab that applies.

11. Set all spin down, sleep/suspend and monitor settings to "never".

12. Apply/OK and Close Power CP

13. Now leave laptop on, let the laptop sit, idle (or use it) for at least 3 hours.

14. Shut down and remove PSU, then restart.

15. If the laptop will not start, or did not show a full charge before shutting down, replace the battery.

16. Go back and set spin down/suspend and monitor power settings to DEFAULT, but do not use hibernation any more on a 3 year old laptop!

SOURCE: What do the various led light colors mean? I have

The LEDs each indicate something is conected or normal. There is one for hard drive activity, power, battery, and wireless. Blue is good. Orange is bad. First take the charger to a shop to have it checked. If bad replace it. If good the the problem is either battery or the connector on laptop. Since the battery is new it sounds like the connector to me.

Dell inspiron 1525 pluged in not charging


When you say it won't charge, does it charge at all?

1. It indicates that it is charging, but as soon as you unplug the charger the battery quickly or immediately indicates it is dead. If the laptop is off, the LED on the laptop shows it is charging but the battery is always dead,

2. It is as if you didn't have the charger plugged in. No light on the laptop at all when the charger is plugged in.

Possible solutions:

1. The battery has died and is no longer capable of taking a charge. An alternate explanation if you can't even get the laptop to turn on even though the laptop charge LED is on, is that the internal power supply that converts the incoming and battery voltage to all the voltages required has died.

2. The power connector inside the laptop is a common failure point. The solder joints break from various minor shocks over time. This is going to become more common with lead-free solder as it is more brittle. Less likely is that the charging circuit inside the laptop has failed.

Does not power on although charging led is on....


You may have a defective battery. Depending on the notebook and battery, try one of following procedures to confirm if this is merely a battery problem:

1. Examine the battery to see if there is a built-in charge status indicator on it. These will be a series of LEDs and a button that, when pressed, will cause one or more to illuminate. If none of the LEDs illuminate, even after the unit has been charging for some time, you probably have a bad battery. Or

2. Remove the battery from the notebook, attach the power adapter, and turn on the computer. If the computer runs WITHOUT the battery installed, you probably have a bad battery.

I have a ex-z77 it is just under 1 year old the camera does not switch on even after the battery has been on charge. when the battery is charging the charger light flashes, im sure the light used to stay...


Your battery will no longer take a charge. Replace the battery with a new one. Your computer probably does not supply the power to the camera. You need a fully charged battery in the camera to view or transfer photos onto your computer.

Not charging


I found out how to solve this problem...first power down your computer. Then take out the battery, remove the power supply, and then hold down the power button for 30 secs. Put the power supply in only (not the battery). Start your computer after everything is done loading up put the battery back in. Give it a min. and then you should be able to roll your cursor over the battery life indicator in the lower right corner of you computer and is should say charging. I have found that other people have had this problem and it has worked for myself and for them.

Battery will not charge


Hi cdravi

Laptops have a power supply control section attached to, or part of the main board. This allows the laptop to switch charging on and off, and control power supply function to different areas of the machine. Sounds like you have a fault in this part of the computer. Off to Dell Service for that one I am afraid.

Need help diagnosing dead UPS


Very likely, "would this also explain why none of the indicator leds are working?"...the dead batteries are your problem. you can try this test, since you had it opened: 1.) disconnect internal batteries, label the wires by terminal location. 2.) connect (2) 12 volt car batteries to same exact wires that you just disconnected, noting correct polarity. 3.) power up UPS. if everything ok, then buy 2 replacement batteries for UPS. if not ok, buy new UPS after through search inside UPS reveals no blown fuses or other faults including poor wire connections.
