When the laptop is conected to the mains adapter and it shuts down for no reseason and you can boot up again after a period, it would indicate that you could have an overheating problem.
Check the fan to see if it spins freely and there are no dust clogging the fan and heatsink assemble, remove and vacuum the dust, if the fan is faulty, replace it.

If it were out of juice you should be able to turn it back on immediately by plugging it in. If it did overheat, simply waiting for it to cool down should allow you to resume using it, but i would reccomend buying a cooling pad they are cheap and run off your usb and will help prevent overheating in the future. If you check both of those and the computer just wont turn back on theres a good chance you fried something internally, most likely your hard drive. If thats the case i would take it to a repair shop where they can pinpoint the issue. Hope this helps.

Automatic shutdown is always cause of overheating, busted heatsink/ fan/motherboard. if the fan and heatsink wasnt replaced yet though they check it fine i would still recommend replacing it. if the problem persists a mainboard replacement would be the last part needs to be replaced.

There are a couple of things that can go wrong with it. The most common thing on laptops is overheating.

You will know if your laptop is overheating if it happens one ore more of the following:
-The keyboard and the bottom of your laptop are very hot when the laptop is working.
-The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
-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.
-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.).
Follow this steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave the laptop in a closed car on a sunny day
-Don't place the laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible, not on your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner

If it is not overheating, then it is a hardware failure. Could be the RAM memory, processor or the motherboard. You can test the RAM with this program: http://hcidesign.com/memtest/MemTest.zip

If RAM is ok, then only replacing hardware equipment could corner the problem.

Yes, it's highly-likely that all your "data" files on the disk-drive are intact. Any qualified computer-technician can remove the disk-drive, temporarily connect it as a "slave" drive in a computer, and copy all your files onto DVD-writable disk(s).

My advent 9617 laptop has started switching of after aprox 1-2 minutes, this hapens in bios, and also whilst booting up windows


reset bios to the factory optimal defaults ..cause this is happening only when the max temperature point of the CPU is set too low and it is reaching it in a few minutes...and shut itself down ...
by getting to bios ..and look for the line when it says optimal factory defaults ...it will remove any settings and suspicions in this direction...after that press f10 to save settings and reboot...If the issue is still on ..check the cpu cooler cause it is dead and it is not cooling the cpu and this is shutting down as a protection .....
also check out if it is charging ok ...it may be the battery ..dieing in minutes..cause it is not keeping juice anymore..

Check if the system is overheating.

You can try to clean the cooling vents using a can of compressed air or a vacuum cleaner (make sure to turn off the system and disconnect battery and charger before you try this).

If the processor heatsink/fan assembly is clogged with dusts, it can cause this problem.

You need to make sure that the processor heatsink/ fan assembly is clean of any dusts.


The following link will give some idea about how to clean the heat sink

(it is for a different make/ model, but the principles will be same.)

Thinkpad T61 Battery Problem


your battery may suffer from'memory-effect'
due to overcharging several times.

boot up as usual, switch laptop to standby-mode
and let it switched on until it shuts down automatically.
this will help to drain the battery to a very low level.
recharge battery until full capacity while laptop is still shut off, boot and measure time until it switches off again.
You may have increased battery capacity this way a bit! If this does not help, get a new one with a better capacity and remove battery when your using laptop at home for a longer time(this will prevent future overcharging), rely an ac/dc adaptor instead, laptop will funtion anyway.

Start by unplugging the non-essential devices one at a time and rebooting.... after you have found which device is causing you problems... use the install program for the device then shut down... add the device and see how it goes.
