1 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?
Update
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
