Laptop repairs

Hi, everyone,

I'm still in the process of deciding what services I plan to initially offer in my repair business (I'll be starting in a few weeks). I know that much of the hardware of laptops in integrated, and thus not easily (or not at all) repairable, apart from drives, RAM, and so forth, but I keep coming across one problem with laptops that I'd love to be able to help with, but has a wide range of ease-of-repair, and that's overheating.

I learned about this problem firsthand a few years ago when my own Toshiba's cooling fans decided on one speed, and that was full-blast, and I could still fry eggs on the keyboard. After some research online I found a great site that had detailed disassembly and reassembly instructions, with lots of photos, and decided to take the plunge. A couple hours later my machine ran like new, and I had a new hatred for Toshiba's engineers, since a process that should have been simple and safe required a full disassembly, down to the motherboard and beyond, just to effectively clean out dust. This was, incidentally, when I first realized that I was at least decent at repair, and that if I (and my computer) could survive that nightmare, anything less was a cakewalk.

Since then I've helped out several other people with overheating laptops, a couple of which were essentially bricks since they reached thermal shutdown not long after boot-up. I haven't found any as hellish as my Toshiba, and a couple of Dells I worked on had a nice access panel to the heatsink, making the job a breeze, but I'm sure I'll need detailed repair manuals for most models.

How do you guys deal with these repairs, if at all? I'm pretty sure that invasive repair of laptops, if not by a manufacturer-certified tech, will void the warranty, so I'll keep away from any still in-warranty. Also, the potential for damaging the machines themselves in the process is much higher than for desktops, if for no other reason than a laptop may already have been physically abused and disassembling it may reveal the damage, maybe even make it difficult to reassemble. The results I've been able to achieve have been so dramatic and satisfying, both to me and the computer owners, that I'd really love to offer service for overheating, but I'd also really love to hear from you old hands out there about your experiences in this area. Do you do this kind of work? If so, how do you protect yourself in terms of liability, signed agreements, etc? How do you charge for this type of service? Any other advice you could offer?

One last note: my experience with my Toshiba led me to make one simple modification to my machine. I now cut squares of used laundry fabric softener dryer sheets and tape them over the air inlets with masking tape. The tape leaves no residue, the material catches all of the particles big enough to start clogging the heatsink, and three years later I've never had another problem with heat. I change the filters once every 2 months or so.
 
It seems to me that if you're going to work on laptops do it, don't just fix a specific issue. What are you going to tell a customer? "I can clean out your fan but I can't fix the power jack." That won't fly with most people and they'll wonder why they brought it to you.
 
nice tip with the laundry fabric softener dryer sheets.

I cant remember the URL at this exact moment but theres a tech with a blog who shows step by step how to disassemble and clean various laptop models.

Hi,

Would you have a photo of how you use these little sheets?

Cheers,

Thanks for the link!

Here's the site I used when tearing down my Toshiba:

Very helpful indeed!

As for the previous reply about specific fixes vs. complete laptop service, I guess I'm still trying to figure out what I want to offer. What kinds of laptop repairs and service to others here offer? What, if anything, will you not attempt to repair? My only total teardown was on my own machine, and it was a real bear! On the other hand, replacement of many laptop components is simple and straightforward. I'm just trying to avoid getting in too far over my head and violating the code of "first, do no harm."

I'd really appreciate hearing from you guys - stories about successes and problems you've encountered in laptop repair.

Thanks!
 
I do laptop repair, everything from overheating to DC jack repair/replacement. I'm to the point where I don't even need to look at a service manual anymore in fact I just tore down an Asus G1S laptop that I never even seen before. Just diagram everything, create a map of all the screwholes and tape the screws onto the paper. But for starts you might want to stick with repairing Dell and HP/Compaq laptops as all service manuals are available online.

As for in-warranty laptops, its not really your job to see whether or not a laptop is under warranty, if a customer brings a laptop for you to repair then do just that. Now if it comes up in the initial consultation or they mention that "yeah my laptop won't boot anymore and I only had it for 4 months" I would mention that warranty.

I really recommend diagrams and taping screws to paper. I've seen people rip apart a whole laptop and drop all the screws in one jar but I usually take a big piece of white paper remove a certain group of screws, tape them down and right below note where they came from. So many screws are very close in size or threads but are not exact.

Sometimes when I get inside a machine I will see that there may be six screws but there are 8 holes. I will often draw that diagram on a piece of paper and note which holes had no screws or sometimes I will take a felt tip pen and make a tiny mark on the board where there were screws.

Anything you can do to help record the disassembly will save you that horrible feeling when you re-assemble and have too many screws left.

Additionally, if you have a good quality digital camera it doesnt hurt to take pictures of the insides if its really scary in there, export them all to another PC and you can view them when you re-assemble.
 
Excellent idea, the screw diagram and tape! I suppose I should learn how to make circles and arrows and such in a photo editing program, too, since I'll definitely be taking digital photos of my work. The main issue for me is building the confidence to work on these things without screwing them up, and tips like these go a long way toward that.

Thanks, guys!
 
Sky, I was real nervous the first few times I ripped open a laptop. Then, I gained confidence. I do the same as NYJimbo, tape the screws onto the paper/diagram. Or I tape them to the shell as they come off.

As to the filter, great idea, and wonder if you could ink them black with a Sharpie.
 
Thanks, guys. Yep, it works very well. Once in a while I'll blow compressed air in the air outlets in the back to remove the small amount of fine dust that's unavoidable, but that's not the stuff that starts the heatsink clogging.

I don't think you'll be able to find that material in black, but it might be worth a look. As for black tape, be careful you don't use electrical tape (the plastic stuff) - that leaves a nasty, gummy residue, especially when it's been exposed to heat. Stick with masking tape.

Another material you could try, if appearances are important, is woven nylon from black ladies' stockings. Cut up some from your private collection next time your toenail causes a run ;) . I like the dryer sheet material because it's coarse and irregular, and dust just loves it. I think it's the same material as those "Swiffer" dusters.

Glad I could help!
