I'm even working on putting 2x 18650 LiIons there ;) I wouldn't be afraid of obsoleting due to lack of batteries.

Also, in case of always-from-AC scenario, it have some benefits, to keep a battery inside (one that you don't care about actual capacity after years of usage). It acts like a integrated UPS ;)

Yes, you are right about keeping a battery as a safety mechanism. But old batteries can also be a hazard unfortunately.

How long do you plan on running your N900 with that battery hack? 45 days or so? :eek:

Ah, OK. It's X redirection we are talking about. It hadn't occurred to me that's what you were doing.

:o Thanks a lot, but I'm just a small firefly here - look at our kernel hacking guys, half of hardware modifications wouldn't be possible without their work.

Yeah, there's a lot of brilliant people. I even recognize some names from the oesf.org (Zaurus) forum :)

I agree. The funny thing is that when I got my first N900 (June 2011) I didn't like it at first because I thought the ergonomics were not good compared to my Zaurus SL-C1000 (screen can be held at an arbitrary angle like a laptop, and larger and better keyboard). So I didn't touch it for a few months. Now, it has replaced my old phone, my camera, my MP3 player, and soon it will replace my GPS receiver.

Shouldn't be a problem on N900, no matter of normal battery (single cell) or dual one (as it's in parallel) - at least, when you plan to not leave it for months without use AND battery isn't many years old.

Problems happens, sometimes, in notebook batteries, because they have cells connected in series. This way, cells that age too much can enter reversed voltage (-) state during usage, and leak/self destruct.

In N900, we're running from a single-cell voltage ranges, so there is no such risk. Even dual-cell scuds/polarcells/etc are safe, as due to parallel configuration, weakened battery just decrease package total capacity, without possibility to enter reversed voltage.

;) Using ~3450 mAh dual-scud (bluedream) setup, on low usage, device last a week (or 2-2.5 days on very heavy usage :eek:), so 6.8 Ah battery should give a 2 weeks runtime, or solid few days of heavy (ab)using.

Yea, that's why it is possible with xephyr and Easy Debian, but not with Maemo itself. Well, technically, Maemo *should* be able to forward own things at 800x480 too, but due to some twirls in Maemo's X, it doesn't work, and no one investigated enough to determine why.
