AS 6920G Restarting

Hope someone could help me with my problem.

I have a three year old aspire 6920g and last year it started to randomly die and restart. Sometimes I'd get an error that would say that windows had suffered a critical error or serious error or something like that.

I couldn't send it in for repair at the time because I needed my laptop for school and I just made sure to constantly keep saving anything I was working on.

Finally, it died and wouldn't even boot up anymore. Couldn't even get to the bios screen. Since I'd graduated already, I sent it in for repair and four months later, I got it back from acer and they said it was a problem with the lcd camera cable that they had to replace. System also came back reformatted and looking good as new. The tech said that it had been running for almost a whole day already and it hadn't restarted at all.

When I took it home though, after a few hours of use lo and behold the problem is back! I was hoping the reformat would address any windows problems and I guess the hardware problem had been addressed too (the replaced cable).

Any ideas what could be wrong with my laptop? It happens very randomly. Sometimes just sitting there it would suddenly die and reboot.

I have tried undervolting before to address the throttling issues and didnt have problems at that time. Could it be a symptom of having voltages that are too low? I tried to raise them again but I don't know what the default values were and despite raising them, the problem continues.

Any help at all would be appreciated. Worse comes to worst, I may send it back to acer since it is still under warranty but I am not looking forward to waiting months again.

 

Make sure that HDD is OK (check SMART status or post it here) and that RAM is not faulty (memtest 4.0)

 

i would not mess with the voltages and just leave it how it is.

i was messing with mine (under volting throttling ect..) and it would crash every time i adjusted something

 

how do i check the SMART status?

Ok thanks for the suggestion, downloading memtest now.

 

i had the same problem dude. mine was restarting and then died. first try to use boot the laptop on safe mode and disable one core of the processor. restart normally and test it with that to see the laptop doesnt shuts down. if it last more than with both processor enabled, then it is processor. ive changed mine and now it works. i have an 6920g too

 

how do i disable one core of the processor?

thanks!

 

on the search bar of windows type device manager. there u will get a list of the devices, look for the processor one open it, right click and choose disable. dont worry disabling there wont damage the laptop. you can disable any of those two. when i tried that i quickly knew it was working because the laptop with both enabled didnt last an hour. what processor has your laptop? the t5550?

 

I've got a t8300 in mine. Ok will try this out next time it restarts on its own.

Thanks for the help! how much did your new processor cost?

 

i bought it used on ebay. it cost 110 its a t9300. t9500 also fits. dont look for the extreme series one, it fits but it makes the laptop overheat fast due to the difference on voltage.

 

Here is the SMART data. Doesn't look like there's any problem.

RAM tests also showed no problem. Maybe it is the CPU after all.

 

thats the same thing i did before knowing of the processor. the laptop worked fine only with the battery and i read that when you use the laptop on battery mode only one core is in use. to change the processor you only have to take out the fan and the heatsink which they are near the area of the ram and HDD. here in this link has some pics it's very easy to remove. hope this helps. i had this problem like one year ago..... died like 5 months ago and realized the problem last week jaajjaja but im happy i have my laptop back.

 

thanks for the help! seems to have worked so far. Been running with a disabled core for more than a day now with no restart.

 

It's 3 years old. Have you tried cleaning the heatsink and reapply the compound?

 

glad i could help dude. but if it happens like mine by the time it wont work with both disabled so remember to have in mind for a new one on ebay. t9300 and t9500 are the best for this laptop. and people say that when a core is disabled the laptop its not running at its full potential.

 

Yup im sure it isnt. I'm just glad to have a working laptop. I only use it for browsing and document processing anyway. Stopped using it for gaming since I bought a ps3.

 

nice then! but anyways i think by the time its gonna break if you happen to get the same situation go a disable the second one. now there you know you have to buy a replacement.
