Can we get back
ON TOPIC and talk old computers, such as how to coax a dead
mac portable to power up? I have one and can get a cracking sound out of the
speaker but nothing else.
If you aren't getting at least the startup chime you have
problems. If you're getting no video and such, the first thing I'd
check and likely replace on a Mac of that vintage is the PRAM
battery. According to LowendMac, it is a 9V battery of some sort,
not the more common 1/2 AA battery found in most other Mac's. Most
of the Mac's I've had won't chime, provide video or anything else
with a dead PRAM battery. After that, I'd check the normal cables
and such to make sure everything is still tight.
This portable Mac is awarded Road Apple for being overweight at that
time compared to other non-apple portables/notebooks and idiotic
power design. Dead without good one and uses non-standard shape
of sealed gel-acid battery especially when rebuilding that battery.
These new cells can be found but not easy to find.
Jeff is bang on on that PRAM battery, two days ago, I had a LC II
stay dead till I swapped out that rare little can taken from spare
motherboard.
Yes, that 3.6V AA1/2 is rare and OVERPRICED around here. 16.xx to
20 ea CDN. Still searching for cheaper sources in canada. Must it
be 3.6V? Or more common 3.0V in AA1/2 or easier to find 4.5V lithium
ones. What about 6V ones? Speak up, because I haven't heard from
anyone on this compatiablity issues.
Cheers,
