ASPIRE 6530G turn off by itself when watching a movie.

I had the laptop for a little over a year. For a long time I hade problem with sound. I could start Skype without first pluging-in the head set as when using the speakers the CPU would go to 100%. At some point that resolved itself a couple of months ago with a Microsoft update. I have Vista BTW.

I had to replace the battery after less than a year.

Now, new problem:
For a week or two, whenever I watch a movie, and it does not matter if it is YouTube, off a DVD or a MPG with Windows Media Player, the laptop just turn itself off after a while. Between 10 and 20 minute into whatching and poofff.

I have to hit the power button and it comes back up.
I work a lot on it, and it has never happened doing anything else and just in the last 2-3 weeks watching movie.

Overheating? But why?
Most of the time, it is in my home office in the basement which is cool.

 

So, are you saying that basically your laptop goes in stand-by/hybernate?

Remember that watching vids using a player or online doesnt count as an "active process" therefore your OS thinks that the pc is in idle state and goes in standby.

Go into your control panel, go in power management/settings, choose a mode (balanced or performance mode, i advice the second) then go into advanced settings. From there, disable standy (it should be on if there are minutes in the box).

I dont remember exactly all the steps (As im using windows 7 now, i dont remember vista very well) but what you need is to disable standy or hybernate state that enable themselves after an XX amount of time.

Then test the machine. Hope it helps

 

Thanks for your answer but that's not it. The laptop shuts down.
When I start it again, it goes to that screen that ask if I want to start normally or in safe mode.

 

Ok so definetly its an overheating issue.
At this point it can be the gpu or the cpu: i would like to advice to use rmclock to undervolt a bit your cpu to see if it solves the issue.

Or use throttlestop by our mighty unclewebb1, that stops the cpu throttling for good.
If you plan to give throttlestop a go,just launch the application,set the clockmod to 100% and turn it on.
You can lower the voltage as well,dont forget to monitor your temperatures.

Use coretemp to check the cpu temperatures while gpu-z can be usefull to monitor gpu temperatures (under sensors tab).

Throttlestop can monitor gpu temp as well, just open the ini/config file and add this line:

GPU = 1 if its an nvidia card or
GPU = 2 if its an ATI

Best of luck!
