I was visiting with our friends Amy and Ryan the other day and noticed a laptop cooler in their garage (a Targus Lap Chill Mat). I asked whether it was any good (as I’m considering getting one for my laptop) and Ryan said that it was but the cord was broken. He was going to repair it eventually (as he’s certainly qualified) but hadn’t found the time. So I took it home to see if I could repair it.
The broken cord, right at the grommet junction. The Amazon reviews show that some people have this problem.
The screws for the cooler grill are inside the case…
Ryan had started to pry it apart but experience led me to believe this was the wrong way to start.
The cover seems to just be a round sleeve.
So I tentatively started peeling it up. The adhesive was not strong.
I was particularly careful when peeling the narrow bits.
The top and bottom pieces that tuck under the grill have a toothed piece attached.
All peeled up.
The USB cable goes through this notched piece that slips around the grommet.
Naked cooler. There are two rows of four screws top and bottom.
The screws removed and the fan housing exposed. It is held by 5 screws.
The USB cord strain relief at bottom. 5 screws removed from the housing.
Two dirty fans.
Untangling the cord from the various strain relief posts and tabs.
The fans are liberated.
The grommet doesn’t seem to move on the cable, so I snipped it off at both ends of the grommet.
I drilled out the bit of cable left, it seemed to pop out.
Slid the grommet onto the USB plug end. Notice the fans have been cleaned…
Stripped the cable ends. This is a power cable so it only had two conductors. There was annoying nylon stranding with the copper that I had to separate and cut off.
Twisted together and ready for soldering.
I insulated the soldered wires with little pieces of electrical tape. I need to buy some tiny shrink tubing.
I used shrink tubing over the whole length of the splice.
I reassembled (in the reverse order of disassembly) and massaged the cover back into position.
All done. It works.
