One possible cause is the charger that is malfunctioning. Another cause may be the battery itself.

My Sony laptop is not charging when it is pluged in on to the electric oulet


If the battery is not charging when the power cord is plugged in then the battery is completely dead and needs to be replaced.

Are you sure your power cord is good and that you are not operating on battery power?

Take the battery out and see if the laptop stays on. Or you can reboot with the battery out and the power cord in. If it fails that means the Power Cord is the issue and you were working off the battery.

If you leave the power cord off and insert the battery, then reboot. If it boots up and stays up that means the battery has some charge in it. If it does not boot up or boots and shuts down, the battery is drained and you will need another one if the power cord is good and it's not charging.

I need to know how to use my new laptop battery correctly.


The first time you charge the battery allow 12 to 16 hours, after that 2 to 4 hours or when battery is charged. If you go on battery frequently drain it right down before charging it, this will give the maxi-um performance and longevity.

Laptop battery went dean charged up pc stioll not turning on battery light just shuts off when press power button and stays off until power cord unpluged and then pluged back in


With power off and unplug from the power supply, remove battery pack from your laptop for a few minutes to force it to 'hard' reset.

Hope it works for you!
Try again and let me know.

Today my cord for my toshiba was behind my pillow and i was lying on it. and I didnt notice, but then it showed that my laptop wasnt charging did my cord just get too hot? will it work later?


The power adapter does not have a temperature sensitive device, therefore it won't stop for overheating if not in consequence of a fault.

Try leaving the power adapter unplugged for about ten minutes.
In the meanwhile also remove laptop battery and put it back.
Connect it back to AC and laptop.
Ensure that connection to laptop and power cord connection to AC adapter box are both well plugged.
Before turning on laptop leave it connected for few minutes.
If laptop still does not turn on and battery does not charge, then the AC adapter is faulty.
A further test can be done using a multimeter to read voltage on AC adapter plug.

A replacement AC adapter is not expensive and can be purchased online. Try entering in Google your Toshiba model followed by the words "power adapter".

Portable batteries are considered a consumable item because as they are used, there is some degradation to the battery. The average life of a portable battery is 300 to 500 discharge/recharge cycles. After that point, the battery's ability to hold a charge slowly decreases, to where it will only power the system for 10 to 15 minutes even when indicating a full charge.

If this is the Original System Battery, then you will need to get a replacement battery to have the system run for a longer period on battery only.

My netbook wont boot, i turn it on and i will hear the fan but nothing else, i was using it everything was going well, the batery ran out and it went into sleep mode, i pluged it in and since then i canot...


Leave it plugged in for about 10 minutes. The battery just needs to charge a little more. Then you can come out of sleep mode.

If it is locked in sleep mode. Just hold the power button down to shut off the computer. Let it charge, you can now reboot, and keep charging after about ten minutes.
