Have a toshiba laptop tuan on work for about 10 minutes and power shuts off what good be the problem

Try shutting down your router, leave it off for 10 minutes then switch it on again. I had that problem with my laptop and it sorted it, no guarantee though. good luck

If the laptop works only off the Power Cord and the battery is not charging, then the battery is dead.

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

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

Don't blame your daughter ;) some Toshiba laptops have this keyboard problem. seems the easiest remedy is;

• Shut down.
• Remove the battery and the AC power.
• Wait for 5 - 10 minutes or hold the power button depressed for about ten seconds.
• Put the battery and power back.
• Turn on the computer.

I believe there is an updated driver for the keyboard you can download from the Toshiba support website that may may prevent this from recurring.

Hope this helps ;)

1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It's nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.

1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes you have to open the laptop case all the way down.
2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
3. Clean the fan and the heatsink with compressed air.
4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

I decided to use a shop vac to suck the dust out and it worked. I tested it by letting the machine run all night and it worked. It's been a couple of weeks now and I'm glad I did it. I was ready to take the machine apart, now I'm glad I didn't. I'd suggest you use a heavy duty shop vac to clean out the fan and heat sinks first.I agree. Try to fix the problem without taking the laptop apart first but I would recommend using a powerful air compressor instead of a vacuum cleaner.
If your laptop is still under warranty, you can take it to any Toshiba Authorize Service Provider and fix the problem at no charge to you.

“My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. Yep, OVERHEATING!
This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:

1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

first try to format the c drive and reinstall the OS if its not working .........

its may be the problem with the smps of the laptop ................

Hi there. This is not forced to work but you can give it a try. Perform a forced shutdown on the laptop by holding down the on/off button until it shuts down, then take the battery out and the AC power for 10 minutes, put it all back together and try again. Please let me know how you get on. Good luck

Remove the battery from the laptop. Wait a minute then reinstall. It should reset, if not then hold down the start button for 10 seconds and it should reboot, if it reboots sooner remove your finger from the botton. That is the quick fix to a simple problem, hopefully it will work for you otherwise it will require moe work, good luck, Gym

thank you for your response....I'm using Vista and the power seems to be on but the screen is down. I have to hold the power button down for 10 seconds to shut down then turn it back on to restore the computer. It is a Toshiba A215-S5818

try more chargers, if posible one made for u;re model , so that u;ll know if the charger is the problem !

i susspect that not the charger gives u hard times but the computers power managment hardware/software .... U can try to open the computer, and look for burned, blackened, smoked, components (capacitors usualy), and if so change them (if possible)
