1. Unfortunately some people call the computer the modem. This is not the modem overheating but most likely the cpu. If you open your computer and look straight in at it, there is a fan. It should be running at all times. Also make sure that it is free of dust. Dust build up on and under the fan in the heatsink will cause tremendous heat issues causing your computer to just shut down. Get some canned air (available in all retail electronic store departments) and blow out the dust from the inside of your computer, especially the fan and heatsink.
2. Another cause could be a bad power supply, where some of the voltages drop so the computer just either locks up or shuts off. I place my bet on a dirty cpu, though.

Dell inspiron 530s.when powered up cpu.fan runs very fast,computer gives 1 beep then powers off.It sometimes restarts itself only for the same thing to occur.


Good Morning--The 1 beep with the Dell Inspiron 530 is due to a bios check sum failure and or possible motherboard failure. The best resolution is to contact Dell and to see what they say. If you have any other questions--feel free to contact us at info@custompcrepair.com

Tip

Laptop is turning off by itself.


Hi.

If your computer turns off after idling for a while, then check power saving settings, accessible from control panel.

If laptop turns off while you are using it, try first reinstalling the system to exclude system problems, or test the laptop starting OS from CD or staying in Bios settings mode, so to exclude installed system.

If laptop is still shutting down, then problem may be overheating.

Overheating usually happens when the fan is not coming , therefore when the computer overheats.Or the fan is not cooling enough and computer is overheating.

Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.

If fan comes up but does not cool enough, then replace the fan, it is not efficient anymore because of a bad bearing or dust. ~Also ensure that fan is well mounted, if fan has poor contact with CPU surface , cooling will be poor.

If fan does not come up, and critical temp is not detected, then the sensor on motherboard is bad, this is very uncommon. When this happens the problem is usually related to system or power settiings , rather than overheating.

If fan does not come up and temp is critical, then fan is faulty, replace it.

There are also more than one fan on many laptops, check that one of the fans (CPU fan, video fan) is not completely ded, and therefore cause for the problem.

By using the software below you can also find out if the problem is really overheating. If temperature results within normal range, then usually it is not overheating.In that case test systtem and check power saving settings.

Here is the software to control your fan and temp. sensor state:

Computer overheating occasionally due to dust blocking the fan


Consider getting a can of compressed air. You can get them from nearly any store, and with a small and long tube so that you can get in and around the fan.

Also consider getting the bios updated. sometimes there are bios changes that fix faulty fans or controllers, which allow the system to cool off better. Go to the manufacturer's site and look up your model and get the bios, similar to what you would do for drivers.

One or both of these can help.

Make sure your Notebook is not overheat if it is then you have to make sure the fan is working and have to work on the NB by placing it on a hard surface and also BIOS update will also help to resolve the issue.

if in case the notebook is not overheating boot to BIOS screen and check if the Notebook turns off by itself in bios if it does then its a hardware issue and you need to contact manufacturer to service the notebook

My sony viao vgn-cs215j suddenly turn off by itself and it takes 20 minutes before i can re-start and use it again and after 15-20 minutes would shut off by itself again without any warning. what could be...


Sorry i nay be a month late on this thread... but better late than never. My Girlfriends sony vaio VGN-CS215J seems to be doing the exact same thing. After buying one of those computer fans that you rest the computer oneverything seems to be running normal. i would also recommend cleaning your fans inside the computer because dirt dust and grime can hold the fans back from cooling down the laptop efficiently and will cause the safety overheat shutdown to activate and shutdown your computer... that way it does catch on fire or fry any of your hardware inside of your computer.

If that does not work... your fans maybe malfunctioning or not functioning at all. this model of vaio has a grinding fan issue that can be very damaging to your cpu if not fixed.

hope this helps,

Dynamic Switchable Frequency of CPU causing overheating


I have a similar problem with my A200. I have to change this setting to Always Low, and also disable the second core, otherwise the computer switches off and restarts. In case it was due to driver updates, I used the Recovery Disc to restore Vista and observed the same problem.
