LCII won't startup

[1vb1]

I have an LCII that when turned on shows nothing. The monitor comes on (I see the usual background) but no blinking question mark - nothing. I do hear the fan come on so I assume the power supply is good. Any other advice?

Thanks in advance.

Replace the PRAM battery is the first step in any old-machine refurb. 1/2AA 3.6V Lithium battery.

Then, do you have a known-good System drive or an OS floppy boot disk?

If the RAM were bad you'd expect some sound effects, either beeps or crashing sounds.

I've an old LC III kicking around with a failed battery. Does anyone recommend a good place to buy them in the UK? Did a quick google search and could only find US suppliers. Couldn't find anything on the Cancom site.
