Hardware, Embedded Systems Last month, I explained why I use generic desktops and laptops running open source software. They're reliable and inexpensive. But this presumes you can fix them. I believe that even those with no hardware training (like me), can identify and fix most hardware problems. To prove it, here's a quick guide. Feel free to add whatever I've missed.

Best trick

The nicest repair I did, after reading the trick on the web, was fixing a laptop mainboard with a kitchen oven.
The laptop did nothing when the power button was pressed except that the fans and the disks started running. Conclusion: defect cpu or mainboard. I replaced the cpu without result so the mainboard was the last option. A replacement costed 2/3 of the price of a new laptop. I stripped the mainboard completely, including the fixed battery, and put for 10 minutes in the oven at 200C. This fixed defect soldering connections and the laptop has been running nicely for three years since then.
My experience with defect caps is that you often need 10 of them, which are nearly as expensive as a second hand replacement mainboard. High capacity capacitors with a 10mm diameter cost two euros each.
