Brand new E-105

[Nights4Saturn]

I just bought a brand new in box E-105 from ebay, and well, it won't power on. The unit charges for a while then the charge light goes out, but when I checked its voltage it was only around 2.5v, and the battery gladly tries to charge again if I just plug it back in. Its actually still charging right now.

Its not too much of a stretch to consider that after sitting for 8 years that the battery has gone bad, but I'm still concerned that it won't power up off the ac adapter.

Any help at all would be greatly appreciated! Thanks!

The Casio devices require a fully working battery in order to power on. No battery in the battery bay is effectively the same as a battery not accepting a proper charge, so far as the device circuits are concerned, at least according to my now rather dim recollection of all things Casio. So you'd need to find a replacement battery. There used to be a site called casiobattery.com but that's been gone for years. A newly-manufactured battery for that model (about 10 years old, last ones manufactured by Casio more than 5 years ago I think) might be hard to find. Here's one googled result. Pricey though:

Of course it could also be the backup battery causing the problem. They last a long time, but not forever. Is there a coin battery hidden under the main battery compartment or somewhere? I can't remember if the backup was easily replaceable on that unit.

Yeah, the unit came with a little 3v back up battery, which still tested good.
What an odd design feature to REQUIRE a good battery to function. Admittedly, I haven't spent too much time around Windows CE devices, but I've still never heard of a device that couldn't run off its own AC adapter.
I found this guy over at Radioshack:

Its a good deal cheaper, though still more than what I paid for the entire unit...

Thanks for your input Gerard! The unit seems really nice, so hopefully I can get it working again (Or, well for the first time I guess...)

Indeed, the 105 is a sweet little brick - that's what all the Casio-envious folks called all Casio models back in the day. And yeah, it's a bit big for a 'pocket' device, but it does a fine job at a myriad of tasks and fun stuff. I played with one for about a week before selling it for a friend. Liked my E-115 better, but still, you should find a lot of uses for it.

just got myself a second hand E-105 and had same problem getting it started.

The battery took a few days - charge it for a while and then stop charging, repeating cycle - thought it was dead but finally it sprung to life.

Manual does say it needs a proper battery to work. It also suggests that then standby battery should only be installed once the main battery is working - so I left it out until I got some life from the unit.

I also did the ROM reset as shown here - but don't know if this helped or not ?

Synced it using active sync 3.8 ( available if you look ) and the Infra red interface on an old PC.

Works a treat now
