Can't boot up my computer

I can't boot up my Macintosh LC II. It keeps trying then it stops with a white screen on the monitor. There are no 'faces' appearing on the screen when it tries to boot. Now after umpteenth times I now get only a dark screen. Interestingley in one of the boot tries I was able to get my open file page but with a frozen cursor. After a few minutes the page disappeared with only a white screen again re-appearing. Can this kind of malfunction be repaired?


I found the battery, Thanks, Ralph

Fortunately, I found an easy way of fixing my problem. With the intention of removing the hard disk, I first disconnected the multi-pin cable to it, but then decided to remove it for the next day instead. I re-connected the cable back to the hard disk. Lo and behold when I switched on the power, the computer booted up in normal operation.

Presumably, the problem was an oxidation film built-up on the pin contact(s) over the past 2 decades on my Macintosh LC II. Disconnecting and re-connecting the pins evidently abraded enough of the film surface to again make good ohmic contact.


Oh, by the way I want to thank both Marian and Mayer for your interest in helping me out. Ralph

Replace the 3.6 volt AA battery and see if the problem persists.

Thanks Mayer for the battery replacement suggestion. I've taken the cover lid off, i can't find the battery. Where is it located? Thanks. Ralph


Here's the PRAM battery you need--just look for it. Good luck. Ralph


It should have a small black plastic cover with a slot in it that pulls off, totally useless part. Just note the positive and negative markings.


I replaced the 3.6 V battery, the LC II still does not boot up. Any further suggestions? Thanks. Ralph

Hy, Ralph!

How's your LC? Did you repair it?

I've just repaired mine. The power supply was KO. I found one (not genuine) with +/-5V&+12V from an old computer.

The battery keeps your settings and should not be a condition for starting. (At least at my LC).

All the best!
