MacFox Posted May 2, 2016 Report Share Posted May 2, 2016 Hello, A few months ago I purchased a Powerbook 100 complete with manuals, case, and floppies for $25 at a local flea market. It has many problems though, one of which being the speaker (at least I hope it's the speaker and not something else). Every time I turn on the PB, I hear a static-y sound before the start up chime plays and while using the laptop, I will hear crackling static every so often. This happens with both the included power brick (which has a cracked tip) and a Toshiba laptop power supply which has similar specs to one of Apple's replacement power bricks. The hard drive will not boot up either, but I heard that changing the PRAM batteries might help with that. But before I buy any new PRAM batteries or one of Apple's replacement PSU's, I want to make sure it really is the speaker that's making the static-y sound and not something more serious like the power board shorting out. The speaker is wired into a connector that also has the wires for the display. I'm not sure if these wires are soldered in or if these could be pulled out or cut? If I remove the speaker and I no longer hear the static sound, then I will continue with buying a power brick and PRAM batteries (CR2430s to be exact). If I still hear static, then there must be something wrong with the power board. Can the speaker be removed? Thanks in advance. Quote Link to post Share on other sites
Macdrone Posted May 2, 2016 Report Share Posted May 2, 2016 needs capacitors replaced first. dont worry about anything else until you do that. Quote Link to post Share on other sites

bibilit Posted May 24, 2016 Report Share Posted May 24, 2016 For your information, the Powerbook 100 needs a lot of them (47µf / 1µ, 10µ...) some are in awkward places and one is in the Processor dauther card. Before ordering have a look at the Logic board, you should order tiny caps, the board being small as well. Quote Link to post Share on other sites
