thanks for putting together such an excellent guide. I had problems for something caught in the fan, one of the connecting screw holders near the power switch being broken , with the occasional grating noise , which became serious.

so great work a true hero like so many others

Many thanks for guide, needed to repair damaged left-side hinge plus top cover retaining screw near hinge stripped, this meant charging jack had come loose & wires broke off! Only needed to go to step 16 to get access, then re-soldered charging jack & drilled through case (carefully) replacing original hinge and corner screws with countersunk 2.5mm bolts with washers/nuts. Almost like new now . . . . original design a bit mechanically weak in this area!

First, my right hinge was damage, then the left hinge was damage. Can these hinges be fixed or replace. Please tell me what I need to correct these problems. The strain of trying to open the laptop with the damaged hinges has also damaged the upper housing just below the screen. Will a new shell solve all these problems.

Thanks in advance for your help,
Selwyn

Thank you for this guide. I have just used it today to re-seat my laptops heatsink with new thermal paste [Gelid Solutions GC-3 Extreme] which has made a huge difference to CPU temps. Combined with undervolting using K10STAT my laptop no longer reachs its thermal limit of 97 degrees celcius. Prelimarly testing using Prime95 to load all 3 CPU cores has it maxed at 82 degrees celcius. Would not have attempted without this guide, never opened a laptop before.

Hay, I think that what you do is great. I have a question for you.

Do you see them two buttons on the bottom of this things motherboard, in the picture of it in picture on step 22 rite to the right side of the cmos battery and rite to the right of your thumb in that picture, also. ?

What are these (2 ?) two ? buttons ?????????. Two seems rather odd to me. I need to erase my bios info, though I do not want to fry my CMOS. ? any Idea.

I forgot my hard drive and bios setup P W. 🙁

Thank you in advance, 🙂

In reply to Andrzej. @ Andrzej, No, you cannot. You have to disassemble everything and remove the motherboard as it shown in the step 23. Only after that you can remove the heat sink and replace thermal paste. If you want to clean up fans WITHOUT replacing thermal paste, you can just remove the top cover as it shown in the step 16 and blow off the fan with air compressor.

Thanks for a really useful guide. I’m wanting to fix the DC power supply, and I’ve successfully got to the part where the screen hinges are off and i’ve released the DC cable connector from the motherboard, but the four wires of the cable (two red, two black) are wound around a small metal block about halfway between the DC jack and the final connector (you can see it in your picture for step 24). How do I release the cable from that?
