Toshiba Qosmio x505-Q885 turning off randomly

[dan3393]

Hello. I have a Toshiba Qosmio x505-Q885.
I've had it for about a year and a half (AKA Warranty = invalid). About 1 or 2 weeks ago my computer turned off randomly. I thought nothing of it, and tried to turn it back on. The problem was that I couldn't. I plugged it in, and the lights indicating that it's plugged in didnt even come on. I took the battery out for about 10 seconds, then put it back in, and it finally turned on. This keeps happening though and I don't know what to do. I first assumed the battery was messed up, so I ran it without the battery (just the AC adapter) and it still turned off. I tried it just on the battery, and it still turned off. Tried it with the AC adapter and the battery and still turned off. I don't think it's overheating because 1.) it doesn't "feel" hot and 2.) sometimes it turns off from being on for 2 minutes, not doing anything demanding and other times I can play Starcraft 2 for 4 hours straight and it won't turn off at all (until I tell it to shut down, of course). The only other "clue" or "hint" I can think of giving is that about 75% of the time when I take it out of my backpack (it is powered off when inside my backpack) I can't turn it on and have to take out and put back in the battery.

I have already called Toshiba but they haven't been very helpful. They told me to restore my system to factory defaults, but I REALLLY feel like this is a hardware problem, but I guess it might not be. I also am no longer under warranty so they can't really do anything for me. I have run Malwarebyte's a few times to see if I have some kind of virus/malware but it comes up clean.


Also, today it has turned off 4 times on its own and 2 times when I turned it back on the media buttons on the side (the lights/buttons for things like mute, play, next song, pause, previous song, etc.) and the SCREEN would not turn on. The fans were running and everything SOUNDED like it was turning on but the screen/buttons never did.

PLEASE SOMEONE HELP ME!!!!

The next time you have it on, run a temperature monitoring utility to see if it really isn't overheating. It's possible that a sensor is failing or that it really is overheating.

[dan3393]

The temperatures stay around these. It just shut down again, this time when I tapped the touchpad "slightly" hard. When I turned it back on again I tapped it hard again and it shut down. I tried a third time and it didn't shut down. I keep randomly tapping hard and it won't happen again. -.- I feel like I have no idea what's causing this.

How could I figure out/fix if a sensor is failing??

EDIT:
Thanks, by the way =]

If one of your temps was obviously the wrong value, it could be failing, but I don't see that in your screenshot. It sounds more like a hardware problem like a short.

I agree, sounds like a short. I don't know much about these types of things, but perhaps a cable came loose? If you feel courageous enough, maybe check to see if there are any loose cables inside your Qosmio?


Good luck and keep us posted with any results.

You could remove battery and AC. Remove, then reseat, your two (2) ram dims. Replace all then reboot.

If machine fails, then shutdown and remove Hard Drive IF you can boot from a DVD or USB stick. The idea is to rule out the installed OS being corrupted.

I think, lile you guys, it's a hardware problem. I'm curious to what Toshiba's flat rate repair may be if all other options fail?

What does removing the ram dimms try to disprove? I'll let you guys know how it goes once I get the time/chance to check it out

Those particular symptoms are usually not good. In my case when I had similar issues, it was a faulty mother board. Since you're out of warranty you may have to sustain the repair burden. However, an appeal to Toshiba can't hurt. You may at least get something off the bill?

I tried that too. And the HDD. No effect.

HP also replaced the power module and the battery (albeit with lesser ones).


Keep us informed.

To make sure your contacts are clean, a problem I had on another machine. I should have mentioned to boot with only one dimm, if machine fails, then boot with only second dimm to rule out a failing dimm which can cause similar failures.

Theses are just cheap easy things to do while homing in on expensive MB problems.

Removing/reseating the RAM didnt do anything. I didnt remove the HDD, but I did boot ubuntu off of a disc. Still no luck. My computer has started to freeze a bit more too. And I just now turned it on and unplugged it (battery in/fully charged) and it just shut off immediately after unplugging. You think this could be a problem/short dealing with the motherboard?

Krane, did you ever solve your similar (I believe) problem with your HP? How much did it cost to fix?
