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.
