    • Do not try to pry the keyboard from the bottom. The keyboard is attached by clips on the left, top, and right side. Metal inserts on the bottom side lock the keyboard in place until they are slid up and out.

    • Be careful not to scratch or chip the computer when prying. If you have a plastic tool that is long enough to gain leverage, use that instead of a metal tool.

    • There are ribbons secured underneath so be careful not to pull the keyboard out too hard, breaking the connections to the ribbons.

    • Flip the laptop over so the keyboard is visible.

    • Insert the spudger under the left side of the keyboard.

    • Carefully raise the side of the keyboard and firmly pull the left corner of the keyboard until it pops up.

    • Run your fingers under the edges of the keyboard along the top edge of the keyboard, from the top left to the top right, to separate it from the remaining clips.

    • Carefully slide the keyboard up toward the screen and out of the case.

    • Unscrew the eight captive screws with a T9 Torx screwdriver.

    • Undo the screws in the order represented by the small numbers next to the screw on the heat sink assembly. Repeat this while reassembling to prevent damage to the components underneath.

    • These screws will also not unscrew all the way.

    • Gently pull up on the 4 pin fan power connector cable to unplug it from the system.

  20. HP ZBook 15 Fan and Heatsink Replacement: passo 20, imagem 1 %32
    • Gently lift the fan and heatsink assembly straight up and out so you do not smear the thermal paste.

    • Thermal paste is a heat conductive gel applied to the underside of the heatsinks. Be careful not to wipe any off or else the components within the laptop will not cool properly and could become damaged. It also makes a big sticky mess if it smears or gets on any other components.

Wow, looks like that graphics card is actually user replaceable? That’s really awesome to see, with both the CPU being socketed and GPU being on a slot, that makes this system super upgradable and (hopefully) long lasting. If you manage to burn your GPU out, you don’t have to replace the entire motherboard.

I performed this procedure to replace the fan/heatsink assembly, and used the HP maintenance and service guide for this machine which can be found at http://h10032.www1.hp.com/ctg/Manual/c03... - it differs from these instructions (an improvement) is two ways - first, the optical drive should be removed before the keyboard, and then the keyboard can be pushed up from below to get it started, which is much better than forcing the whole thing from above. Secondly, removal of the top cover does not start with separating the front edge as these instructions show, but by lifting the back edge and then sliding the cover forward, which takes very little force. The Ifixit instructions were a good start, but I was glad I had the real stuff from HP.

What about electrostatic discharge though? How does it fit into the picture, and how does one protect against it?

I did this in order to clean up the innards and apply thermal paste. I gotta say it’s a hastle compared to the older EliteBooks where all you had to do to access the CPU was to open the service door/cover.

But eh, what can you do, right?

Great write up. However, these copper pipe type coolers don’t fail unless you’ve busted the fan somehow. For those of you with this overheating problem, just take it apart and put new thermal paste in there.

My 6yr old machine was overheating badly, and would BSOD on occasion. A quick look with hwinfo revealed a cpu that was hitting 100°C.

Too hot!

I blew in the vents with some light compressed air and this blew out a small slug of lint.

Didn’t help much.

Ran Aida64 FPU and it would immediately overheat and throttle

I went by the pics on here and knew that my fan was operating normally so I figured I’d try new paste before dropping $50+ on a new fan.

Pulled the heatsinks out, put some new Artic Silver on there and put it back together.

Now even under Aida64 FPU it’s only hitting 93°C now and no throttling.
