Your system isn't sleeping, it is turning off due to thermal overheating on the processor. replace your fan and try again

Dell Inspiron 530s Desktop fan motor keeps running


It\'s NOT the fan. Check the power save settings on the computer ITSELF. Check your BIOS settings as well. Inspirons ALL do the same thing with waking up.

A85S107 Toshiba Laptop: Laptop will run for approx 6 min and gets hot and shuts off. Cooling fan clear and runs properly. Tried cooling pad to no avail.


If you are sure that it's not the fan in question then you'll need to check the heat sink could be too much or too little thermal compound

Automatic shutdown over heating


Turn the computer off.
Remove the side-panel, to expose the motherboard.
Turn the computer on.
When you see PRESS <blah> TO ENTER BIOS SETUP, press the <blah> key.
Use the "arrow" keys to move around the BIOS SETUP menu,
looking for any "system health" menu-entry.
Press the "enter" key to select that menu-entry.
It should report the current motherboard temperature, and the current CPU temperature,
and the temperature-limit, beyond which the motherboard will force a shutdown.
It may also report the speed of the power-supply fan, the case fan (if installed), and the CPU fan.
Also, take a look at the fans, to confirm that they are spinning.
Replace any non-functioning fans.

My sony vgn-cr220e sound is very low and is also always running very hot


The heat sink may be clogged with dust and ifthe BIOS temperature sensor controls the fan speed then it may be compensatingfor the reduced cooling by the dust build-up.
If you are not using your laptop on a flat surface, it may beobstructing the cooling vents on the bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

Sir i am having hp 520 notebook. when i m starting it some times it form a unusual sound and unable to start.if i press esc key it will start,but the starting icon get selected,if i open my computer then...


old vista 520.
funny sounds are most times lent in the fan vents or fan full packed in lint, or HDD going bad.
ever get your PC serviced?
so you find the boot menu in BIOS
and picked HDD to boot
and it boots to VISTA right.
then the touch pad is failing.
try an external usb mouse for $3? maybe the touch pad is bad.
if the HP touch pad drivers are loaded and not corrupted, the touch pad is end of life. as all do, old. same with all mice,
there are hot keys to move the cursor, but must be learned.

why use a real mouse, or get the thing repaired.

Fan runs constantly.


OK generally the Fan is controlled via the CPU, settings can often be adjusted in the system BIOS, that is accessed before bootup by pressing a key, often the DEL key straight after switch on.
There is a program called speedfan, this is an excellent free program that allows controll of ya fans it has extensive help and is easy to install and use.

Ensure that you did not press the conbination of keys that switches to the external screen, on thinkpads this is Function key , plus one of the numbers.

Check if the computer is in sleep (hybernate) mode, in this case you should be able to wake it up with the start button, or on some model with the wake up button.

IF you still cannto restart the computer, then it is probably frozen, remove battery and try to restart the laptop in this way.

After restarting check the power settings (you find them also on display properties/screensaver, or in the control panel). set the computer not to turn off.

If the computer screen does not turn on again doing the above, or there is no way to wake it up when it goes in standby, then the unit may be faulty.
If the computer is new, in this case, better getting a replacement or a repair.
