Hi again!
My second laptop project was to fix a badly cap leaked Powerbook 100. So far I was able to make it to work with capacitor replacement and the computer became usable again! I also did a comprehensive cleaning procedure for this laptop. I'm going to max out the memory with Siliconinsider's beautiful purple RAM module. I was also planning to install an internal version of BlueSCSI (or SCSI2SD?) for hard disk replacement. This laptop came without an original HDD.
One thing that I noticed after of little use is that the Powerbook 100 is emitting an annoying high-pitched sound when it is powered. I was able to locate the area where that annoying sound comes from. It is near to battery area, on the right side of the motherboard. Some SMD coils are laying around on this area of the motherboard. I wonder if I could fix this coil whine issue by replacing these old problematic coils with newer ones to eliminate the coil whine? Does anyone here know what are the correct values for these SMD coils? I suppose these kinds of components are still available from the electronics part store like DigiKey, Mouser, etc. Has anyone done here also an SMD coil replacement in addition to basic SMD recapping?
