The pc keeps switching itself off - Acer Aspire 7520-5185 Laptop

You have an overheating issue.

There is little info on your problem but I think you mean the screen went black while downloading a film. Normally computer monitors turn themselves off (dormant) to save energy and the life of the monitor's screen if not used for 10 or 30 minutes, depending on the settings, but the download just keeps going. Mine is set to 10 minutes. All you have to do is disturb the Mouse and see if the monitor screen switches itself on. There is another power saving option, and that is the Computer itself. If the computer is not used for one hour, it too goes dormant, but can also be set to switch itself completely off after the download is completed. However, if a computer is left on for over an hour, it can switch itself off to save energy and the computer's own wear and tear. It all depends on the computer hardware and the settings. If it is hardware controlled, then it may or may not switch itself off but it still goes dormant. Or it can be set to whatever you wish it to do, stay on all the time, go dormant after a set time or switch off if there is no prolonged activity.

Hello

By know you should of fixed the problem .
1. keep the inside cabinet clean.
2.If the unit keeps shutting down by itself after a certain time and it is not dirty inside the cabinet .Also all the intact screens are clean . Check your Personlization settings By right clicking on your screen . then right click Screensaver and then power settings . Then check to make sure all the settings are turned off unless you want the computer to shut down after a certain amount of time

Try logging in safe-mode and see if it switches its self off.
To log on in safe mode, power the laptop on and keep pressing F8, choose safe mode using the arrow buttons, continue to log on. when you successfully log on, leave the laptop for some time to see if it will switch itself off, if it does switch itself off, then definitely, that will be a hardware related problem.
if it does not, then that's a virus causing it, email on [email protected] to solve the software related problem.

do you mean its switching itself on and off randamly,if so go to control panel,then to power,and ajust the setting=shut power off at 5mins,10 mins or NEVER,click never will solve the problem

the processor fan might not be working due to which the laptop gets heated up and switches off. if u dont replace it u might end up burning the processor.

Are you using 3G SIM card? It looks like your phone need firmware is outdated. Try reinstall or update your firmware through Nokia PC Suite. DON'T FORGET BACK UP YOUR DATA. If this doesn't help then is a hardware problem and that mean you have to pay a visit to nearest Nokia Centrum.

if you can get into bios check and see if there is any type of alarm or auto on set up. If not or if its not that big of a deal just use the switch on the back of the power supply at night. Make sure you shut down your computer before switching this. It will definately keep the computer from turning on by itself.

my phone just keeps switching itself off, can anyone advise me on what the issue might be

start> settings>system tab>button lock> tick lock all buttons except power button. that could be the answer you need
