I broke my qosmio......

Hey everyone. My toshiba qosmio recently has (had) been throttling super hard. The first time this happened, I tried blowing compressed air through but that was not doing the job. Then I took it apart, all the way to where I could see the fan. I blew out SO MUCH dust. It felt so good. That was about a year ago. Then again, a couple months ago, it's been slowly getting worse. In order for me to play anything, I have to set throttlestop at about 1.6GHz otherwise it will throttle to death, and if I turn off throttling, within 20 minutes the laptop just simply turns off itself. So, then I opened it again. I followed the guide, but this time I took the actual motherboard out, to where I flipped it over and saw the cooling mechanisms.. Once I got there, I decided I was going to leave this for another day, considering I hadn't bought any thermal paste or anything yet, but when I put it all back together, it won't turn on. (I wasn't wearing a grounding bracelet or anything ) When I plug it in, the red light at the front turns on, and when I press the power button, the blue ray spins, the fan spins, not sure if my SSD "spins", but nothing ever comes up on the screen, external monitor didn't help either. I'm pretty sure it never posts, but I'm not super certain of that definition. I don't know what I did wrong, and now that it's broken, I don't know who/where to go to to fix it... I really hope maybe someone can help. thanks guys ,-,

 

Never done that either. Must've rebuild a several dozen laptops by now and nothing ever came of that. Try a multimeter; you're not even reaching 0.5V, no worries. Forgetting to remove the battery, however, is quite another thing ...

Just get paste or thermal pad and reseat everything properly, you're likely seeing thermal overheating (or a disconnected cable). Memory banks are finicky too; even 'clicking in' isn't a certainty. And don't run a cpu without proper connection to its heatsink. Auto-shutdown's good and well, but if it kick in too late it's not just the cpu that's in trouble.

 

Well, the thermal shutdown was only ever a problem after gaming. I never messed with the heatsink either. All I did was take out the motherboard, simply found the heatsink, put it all back together to find out it won't post. Maybe the memory isn't seated, I'm not sure. But I don't know how to try and fix it. Can I troubleshoot? Where do I take it? :/

 

Taking out the motherboard means taking out every cable that's connected to it. And it's a bit unusual to leave cpu and memory attached to the mb when removing it ... and it's quite a bit of work, to boot.

A repaste and cleaning dust on a gaming system is pretty much a necessity anyway, so do that as well. And, if you haven't touched the ddr banks, then make certain the keyboard cable is properly connected to the mb again, made that mistake a few times; no boot.

...

Just a hunch; " motherboard" = " keyboard", perhaps? That, at least, would make a lot more sense to your story. If so, firmly reseat keyboard cable and you're good.

 

I wish it was just the keyboard. I unplugged everything, and in this qosmio, when you take out the keyboard and the top frame of the casing, you can't see the gpu/cpu. They're on the underside. Once I got there I realized I wanted to try this later, but when I put everything back together (trust me, i stared for 30 minutes looking for something unplugged), it just spins fans/bluray and doesnt show anything.

 

Alright, try removing both battery and cmos battery. Then hold power button for several seconds, that should clear bios to default. Put batteries back in and reboot.
