Overheating? My zd8000 gets very hot and shuts itself down. All fans are working - help!

“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.).

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.

These devices get hot when they work. they need cooling. if the cooling system get dirty and fan cant turn clearly then it stops itself for protection.  it need to be cleaned. 
hope it works

It could be that your laptop is overheating. Most computers have a heat sensor that will shut down the system when it starts to get to hot. Next time it shuts down, check to see how hot the air coming out of the fans on the laptop is. If the problem is overheating, be sure that you always have it sitting on an area that allows the fans to push the hot air out of the laptop. If it still overheats, you may want to get a can of compressed air to clean out the fan itself.
Hope this helps.

There is a software called "SpeedFan" which you can download here

This software will tell you the internal temperatures of the computer (so you can figure out if overheating is the problem). Most of the time overheating is due to excessive dust inside the laptop. The best bet is to get a can of compressed air and clean the inside out. This does require some disassembling of the system, so if you are not comfortable doing so I would advise you to take it to a local computer shop.

Another solution would be to purchase a "Laptop Cooler", this will lower your temperatures anywhere from 5-10 degree's, but can get annoying to lug around with you. You can view some laptop coolers here

If you happen to run the Speedfan application, let us know what the temperatures displayed as, and I can tell you if it is running too hot!

it might be broken... Call a proffession and get it fixed

sound like it is overheating. my suggestion would be to use a laptop cooling mat(found at bestbuy radioshak or circuit city)

hi
when ever cpu overheat fun runs automatically if not try to update your laptop bios . Hp website has updates of your laptop bios.
thanks

is it hot ?
if it is, it is overheating, try to clean the cpu fan.

It sounds like an overheating problem. When it is booted, does it run ok other than just being slow? Check your cooling fan and make sure it is running and not stopped up. That is a number one symtom of overheating is freezing and rebooting by itself. There is a free program called "Motherboard Monitor 5" that will monitor the temp for you and set off an alarm when it is getting to hot. Check that problem first. Hopes this helps!

On many overheating problems we tell our customers to shut off the laptop, place a fairly strong vacuum cleaner flush against the bottom grill and hold it there for about 30 seconds. This sucks out a strip of dust that gathers on the cooling grid over time.
