Did I fry my laptop? - Alienware MX11r2

post #1 of 9
Thread Starter 
Summary - Tried to replace thermal paste on wood table, add an ssd and keyboard. Laptop does not power on, even with AC/battery.



Full Story
My sister got a hand me down laptop, the alienware MX11r2 and the keyboard's s, d and e key stopped working. I bought her a new one as she needed to use this for school and it was easy. I then installed a Samsung 120gb ssd in and installed windows. Everything was fine. However, I realized that the laptop temps were a little warm and that the laptop is almost 4 years old, so I decided to open it up completely and replace the TIM. I followed a youtube video and opened it up and removed the heatsink from the motherboard. There was a lot of thermal paste on it, so I took a tissue, shirt and cotton swabs and used arctic clean to clean the intel chip and nvidia chip. After that I installed pk-1 thermal paste and used a credit card to spread it on the chips. The old TIM was thick and there was some that seeped to the side. I tried cleaning most of it off, but there is still some residue left on the chip that I decided to leave there as I don't think it would affect anything. I also read that arctic clean and pk-1 thermal paste was not conductive, so I didn't worry.

I put everything back together and tried powering it on, no go. Opened it up again and checked all the connections, they're connected. Swapped out ram, no ram, motherboard only. Cycled the laptop by holding powerbutton and removing battery, connecting it to ac. I got nothing. The fan doesn't even spin up and I have no error noises or led lights from the keyboard/front.

I think I may have shorted the board maybe? I wore socks and sweatpants and although I kept touching my corsair 650d case to ground myself, I probably messed the motherboard up maybe? Even so, I cannot even find the motherboard on ebay.

Specs - Alienware M11x R2

It takes a lot to fry a motherboard. You did not do that, most likely you forgot to plug something in. Before you go into a project make sure you do your homework. As far as grounding yourself, touching the case every now and then does not have effect on the grounding.

Raaageee, There are only two cables connecting to the motherboard from the power switch. I checked both and they're secured. And the power jack and battery connection are directly on the motherboard. stun.gif

I'm going to re-check on it tomorrow, thanks for giving me hope that it might still work :O.

Yeah, just like above, it looks like you forgot something of that sorts. Good luck! thumb.gif

Be sure you plugged in all the fans, as you had removed the heat sinks to reapply TIM. If even one fan is not plugged in on laptops they will not start up, and if they do, momentarily afterwards you will receive a blue screen for heat. When you have it open again take a picture. If you have the extra time, take everything out and rebuild the laptop. The best way to reduce chances of static would be to place the components on cardboard. Please, when you build it again do not touch e brass heat pipes. The Grease on your figures will damage them.

Well.. Crap. I did touch the heatpipes. I also touched the heatpipes on my 7870 xt GPU o_O, they look like the same material too. Should I just wipe it with a cloth?

I remember trying to remove the fan power connector from the heatsink, but it didn't go out so I didn't bother. Maybe it isn't secure, I'll give that a go.

I built on a wood table, I guess I'll move to some anti static motherboard bags (assuming they're anti static from the outside). I took pictures on the first go, unfortunately I was using a 50 lens and i didn't get full sharpness on the pictures.

I'll try giving it a go tomorrow

Yeah...You shouldn't be too worried about static. Yes, it's a good thing to keep in mind. But the chances of it happening are next to none. Most of the technology we have have grounding, so when the system starts up the extra electricity is offset.

I would try trying to start it with a paper clip in the power plug in on the motherboard.

If the keys were broken is it that far of an assumption to think the power button might be too?

I don't see an easy way to jump start the motherboard as the power connector has a wire going through the main lcd and then a single large wire from the lcd connecting to the motherboard.

The keyboard is connected directly into the motherboard. :O

Once again, need to test when I have time.
