Are you getting juice out of the power cord? You could use a multimeter to see that you are getting the rated power out of the brick. Sometimes it is as simple as a plug not making good contact.Find a voltmeter and test if the adapter puts out any power at all. Make sure the RAM is properly seated, unplug every peripheral (even the cd/dvdrom drive), power it up on direct electric power. Check if you can get into the BIOS (F2, or F10, or delete, or some random key depending on the manufacturer, that you press when you power up).

Most laptops have a little light showing that they are recharging when plugged in properly. Is there a green LED light? Alternatively, I had an old laptop where the brick had a removable power cord and one of the prongs in the adapter where the power cord plugged into the brick would sometimes get pushed in and fail to make contact. Once I had that plugged in properly, I never unplugged it again.

If it fails when trying to boot windows, you could always try to download and burn an ubuntu live-cd and boot from the CD to see if the problem is really your software.

AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.


So your saying the charger will charge the battery, as long as the laptop is off...But when it is charged, you remove the ac adapter, start up the laptop, running on battery power alone, then hook the ac adapter to it, and the laptop cuts off..???

Toshiba Satellite won't start up when AC plugged in


Try another Cord/Charger to verify the Cord, AC jack. If you plug in the AC cord after starting on battery, does the battery charge? Open Control Panel, Power Options, set to High Performance, Advanced power settings, set Sleep and Hibernate to Never, Adjust Advanced power setting to your preference.

Toshiba Satellite A45-S120 laptop battery does not charge


Sounds like you need a new battery. Try removing the battery and running the machine on mains power. If that works, you know the charger is ok. Its usual for batteries to deteriorate over a few years, so my money would go on a new one.

Hi, my laptop crashes when the ac adaptor is plugged in yet it will charge the battery fine when the laptop is shut down.


Problem description: The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.
Possible cause: 1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution: First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.
If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

Shuts down


Is this laptop brand new? Because normally, when you plug in the power adapter, the battery charges up to 100% and stays there UNTIL the power adapter is unplugged. Then it will start to run down its power. It's not supposed to run down with the power adapter plugged in. Also, if you take out the battery and only plug in the power adapter, it should work fine. If it doesn't, then there's a problem with the adapter.
