OMP glitching?
Posted by: Retro Rider on 2018-08-12 17:10:16
I got an OMP (MessagePad 100) w/o a battery plastic thing, so I tried to use a power adapter, I used a PSone power adapter (7.5a - 2a) and the screen glitched. Was it the power adapters or something else?

IIRC standard batteries(4 AAA) can be used here with a small modification.

I did hear that some people were reporting issues with capacitors on the earlier Newtons, not sure which as I have no recent experience.  Just something to be aware of.

Really? can you send me a link or somewhere where I can find how to do this?

I actually also posted this on Reddit and they said it might be the LCD ribbon cable has corrosion.

runs on 4 AAA batteries

Afaik, the MP 100 needs to have the battery pack installed to function, even on a charger.

There's a switch that is depressed when the pack is installed.

It's probably detailed in the User Manual.

It also needs to have a good backup battery installed.

I cracked open the battery pack on my MP100. It looks like it could be rebuilt with new rechargeable AAA's.

I haven't gotten around to finishing the job.

i agree with that, but the switch can be fooled.

Can't find information anymore but IIRC a special cradle was supplied for using standard batteries , you can rebuild the battery pack with Nicd units:

Yes, it can be. Yes, there was a battery thing to hold AAA batteries in the Newton 100, that's what I need, idk if I can rebuild one of the rechargeables

I did hear that some people were reporting issues with capacitors on the earlier Newtons
Actually, now that i've spoken to a friend with basically the same problem, it might be the capacitors
