How stop my computer from shuting down

My computer keeps shutting down I bought a new battery and cord. Yesterday I had 100% battery and did not use it anymore until this morning, but it told me that now I have 0% battery and to use power outlet to stay on. I have used power outlet and it will not come back on at all. I hit the reset button and it still won't come back on. I see the lighting bolt light come on when I try to power on, and sometimes when I am not using it the the first light is always blue and flashing. Help Me Please!

lol last guy was funny be alot things proably dam power adpter not sending right watts for that 9100 buy new power suplle dell only try again k

I have a toshiba laptop which was unexpectedly switching off. The laptop was 2 years old. I did lots of searching online to discover this is a VERY COMMON ISSUE.

The problem is, dust blocks the heatsink. When I took my computer to pieces, I found a strip of dust half an inch (1cm) thick covering the back of the heatsink which prevented air flow. If your laptop is a couple of years old, this could be the problem. When I removed this dust, the problem disappeared.

If you are computer savvy, then try the following - if not, take it down to a computer shop!

1) Remove the 5 screws holding down the heat sink cover and processor cover. These are on the bottom of the laptop, in the centre, at the back.

2) Remove the 3 screws which hold in the heat sink in place.

3) Remove the heatsink

4) Take the dust out

5) Re-assemble

a note: be careful not to get dust in the thermal paste on the cpu - unless you have replacement paste.

Good Luck!

I would suggest that the power supply is going. i had a desktop that would do the same thing, I put another P/S in and I have not had the problem since.Tthe battery is a clean, stable DC power source as opposed to the P/S that is a regulated AC/DC transformer. Worth a try to plug it into a UPS and try again as the UPS supplies a cleaner AC source.

check screensaver/energy saving settings in control panel and set to two hours or longer.
if problem persists may be hardware issue
ie. overheating

might be a lot of things (with the little info you provided).

Is your cooling still okay? Do you have the same problem when using your computer for other things that heat it up? (like gaming or 3d rendering?)

or is it just your computer shutting down because it isn't 'used' for a while? Like the sleep mode?

How I solve my Acer TraveMate Laptop computer from shuts down due to over heat problem.

1. Confirm the cooler fan still in good condition ( it still can spin when the laptop become heat).
2. Power Off, looking at the laptop bottom side, find the cover plate that cover the memory ram & wifi module,
3. remove all the screw and then remove the cover plate,
4. looking for the cooler fan connector wire, (3 pin fan connector), don't know which one ? please refer to http://www.allpinouts.org/index.php/Motherboard_(CPU)_3_Pin_Fan_Connector
5. use a wire cutter and CUT THE YELLOW WIRE
6. test run, make sure now the cooler fan always spin in high speed,
   
7. use nhc ( http://www.pbus-167.com/ ) to check the temp. it show that the cpu temp 70~75, hdd temp 50~55
   

Whell if nothing helps then you should try this. You can go to control pannel and open power options, and there set the parameters so, that the note book never turn off or go to sleep or go to hibernate when plugged.You have four places so just set them to never and that sholud fix the problem :). Was this helpfull? *I did this to my notebook and it never turn off, or something when plugged!)

Go to bios. Leave your computer on for a while. if it turns off by itself, its overheating,Take a vac and clean out your computer. If that fixes it, it was dust in the fan.

Shake your computer. If that makes it turn off, something is loose.

Run a live linux cd. If that works, you have a software problem. If not, you have junky a processor or your memory is bad.

I charge 20 bucks to do this

I have an old Acer series 220 which I keep for emergencies. Well the emergency has come because the hard drive on my PC has decided to quit. But then I found the Acer kept shutting down, sometimes after only a few minutes, due to overheating. The fan didn't seem to be working at all. I found a solution!
I am supporting the laptop on its front and back edges on blocks of wood so it is 2 inches off the desktop. Then I am using an ordinary domestic fan to blow air sideways through the gap under the laptop. I was amazed to find this simple technique cools the laptop so effectively that it doesn't even feel warm any more, whereas before it felt really hot after a few minutes.
Not a very technical solution but the laptop now keeps running for hours without a problem. Good enough until my PC is repaired.

(You can support the laptop at its side edges but then you'll have the fan blowing directly at you from behind the laptop.)

my laptop overheats after about 10 minutes, and it shuts down on its own when im doing work im not able to save it.

perform a stabilty test on nur pc using everest software if ur pc shows a blue screen during the test then there might be a thermal issue.also scan ur pc using a good anti virus

Also clean the CPU area including the Fun and insert properly when you put it back.

Let's diagnose the problem:
- Check your Power Settings on Display Properties they have a choices to apply settings.

hi i have a acer aspire gemstone 5720z laptop and it keeps cutting out when i try switching it on or it comes on then cuts out please help what could it be

it can be many things like sleep mode,hibernation which can be changed to suit;but your'e prob seems to be either compatability conflicts or lack of physical ram.
seems to me you pc reverts to compatabity saftey mode to protect pc.
On software that causes your problem you either need to change resources or uninstall and reinstall(this way auto config and use different resource)
If its lack of mem install more memory(ram)

Hi there if you have installed hardware in the laptop new or old it mite be a good idear to take it out and see if that help if it is still shutting down it mite be the rams,hdd,cd,dvd,wifi card,moden card,cpu or the motherboard it self mine was shutting down as well I removed my cards and left one of the rams in that I new that was good and I started it up and stayed on I found out it was my TV card that made it shut down so I hope this help.
