There are a whole lot of possible things here. It could be that the laptop is overheating, due to dust in the cooling system. It could be that a component in the video system is failing, and will get worse. It could be memory is failing, or the processor...
Things to test. If you laptop has lights for keyboard caps lock or num-lock, do those change when you change them? If not, then the system is hung, and it's not a video thing.
What is happening is that the processors thermal shut down safety is activating. Cleaning the fan and vents was a good first step but there is something else that needs to be done in order to make sure the processor is not overheating. First, make sure the fan is running at all times. If it is for the duration you're observing and the laptop is still shutting off, then the problem may lie at the heatsink-processor interface. This is where the heatsink sints on the processor face and has a thin layer of thermal paste between the two. If there has been a breakdown in the thermal paste and it is not doing its job, then you can have a thermal shutdown.
Now, the nice thing about your system is that you can clean the heatsink fan and grills just by taking off the bottom panel. Unplug the wiring harness for the fan and unscrew the heatsink off the processor slot. Clean the surfaces well with alchohol and let dry, then apply a very thin layer of thermal paste to the heatsink, screw it back down on the processor. Now leave this panel access door off while you power the system back up, that way you can easily observe what is going on in this area. Make sure to use good clean compressed air from an pffice supply chain to blow out all vent and compartments. Do not use the sir while the system is powered on just in case some condensation escapes from the can.. Good luck, below is the link to the service manual for that laptop. An illustrated guide of the disassembly starts on page 70.
That sounds like a power supply problem. That would be the first thing I would check. If it was the processor, you would have heard a long beeping sound or if it was the memory you would hear about three 'annoying beeps'. The main reason you indicated there is no display on the screen and that the fan spins for a few seconds then shuts off, would hint that power is not going to the mother board long enough to spin the processor or cooling fan. Hope this helps :)
It sounds like a driver issue. Check for any updates to drivers for your laptop from the toshiba website.
if you have a restore disk, you may wish to back up any important information and use it to reinstall your operating system to factory default. Since it charges when turned off properly, it does not sound like a hardware issue.
I have a toshiba and that is exactly what the fan is doing to cool off the processor. That is because when you boot XP the fan stops after 30 seconds is simply it has no difficult operation on it. But when you choose to switch on to Ubuntu your fan doesn't stop is because ubuntu requires more air since it has so much effort on its operation. Mind you when you installed ubuntu, it requires larger video graphics memory than the XP OS. Try to execute more websites on different tabs on your XP and you will find your fan will work overtime because you put much required operation for the processor. But to help the fan cools off the internal devices, place cooling pad beneath the notebook so that your PC will be safe.
Since your fan works, we can assume the power is fine, so the next probable cause is the main board (where the processor, memory, etc are). Unfortunately, there is no way to test it (unless you have a spare one).
hello, am temab concerniong your problem on powering your system right?
I hope the best thing for you to do is by checking whether the processor cooling fan is running cause that causes the system not to power on or power on and before short seconds it flickers and go on off again . there is nothing wrong with your power jack. If the problem is that the pc fan is not rolling then change the fan but if the fan is roling then change the processor itself. any other question?
