These power adapters are almost impossible to buy, or rather obtaining a cheap adapter with the correct connector is very very difficult to find. The original adapters cost 800-1200 baht.
I ended up having to get a power supply which had the correct voltage and current, but which had a 5.5 x 2.1 mm plug, and then get an adapter. Unfortunately, the first was a little too loose, 3-8-2.9 mm.

No new content here, unfortunately, but related to my Dell WFP3008 and the sleepy iMac issues, I found a couple of semi-relevant videos (w.r.t. opening an iMac and cautionary tales when dealing with LCD panels), again from CuriousMarc…

Following on from Dell M6700 or M6800, there are a lot of laptops sold without power supplies or chargers. This made me wonder:
See M6600 Owner’s Review – Warning – Large pics – Personal Opinions for an interesting break down of the power supplies and current draw.
Anyway, I thought that instead of buying an expensive new, or second hand, supply (the 240 W or 330W can go for up to £100+), is it possible to to fix them? Is there a common failure mode? A recurring point of failure?
DIY time… precision power supply following Dave’s design…
Following on from Sleepy iMac, here are some capacitors that might be a good fit.
Following on from Sleepy iMac, where the A1058 iMac G5 was constantly sleeping due to overheating, I thought it would be a good idea to publish the logs (Applications>Utilities>Console>System logs).
I was provided with a second hand G5 iMac 1.8 GHz (A1058) PowerMac 8.2 (not A1144). Unfortunately, it overheats and then shuts down, or rather, goes to sleep, shortly after being powered on. This self imposed sleep happens quickly, especially if the processor is being pushed, such as by running a full screen video in VLC.
