The battery seems to be at ~7.98 V and the leakage current is 14 mA. Which leaves the computer bootable for a maximum of 9 days after last charge. Battery controller is MAX8724.
Any idea (educated guess) what might be draining the battery ..? There's quite a few people that bought these ;)

Can I guess(tm)? It might have WOL (wake on LAN) enabled to turn the laptop on remotely. If so, there's power to the ethernet and/or wireless adapter even when turned off. I dunno if the eee 900 even has WOL, but it's worth checking the CMOS and the OS settings.

Also, check for modem settings if it has one. There is often a feature that listens in on a phone line and turns the PC on when for example a fax comes in. At least the PCMCIA modem in my old Compaq had that and it came with a warning not to leave active unless needed.

Well that's been discussed in the original eee forum thread. And the consensus is that it kind of defeats the purpose of a "mobile" unit. So it can be done but it's quite inconvenient. Guess the switch-in-the-case mod is coming up soon ;)
Or the simple fashioning of a piece of tape to place in just the right place, so the "disconnected" battery can be stored in its normal location, alleviating most of your "inconvenience". Use the right shape piece, and it can be removed without detaching the battery, putting it back into service virtually instantaneously. The switch installation is likely still the easiest, if the right switch is bought.
14mA is not "leakage"; in some quarters that is close to a short. Perhaps that is Maxim's way of generating income from the few, rare items they (somehow) manage to sell.
Here's my blinking light story. A few years ago they got the entire tech staff new Motorola v60 cell phones. Out of the box the damned things had this little blinkng LED. If you left it on it'd drain the hell out of the battery. Turning it off gave you about 40% more battery life.
I've seen the Eee PCs at Central Computer, including the new 1000. Very nice. If it had a cardbus slot, I be a customer. I don't recall seeing anything like a 232 port. That 10 inch model is at the point where it is big enough to be usable.
I designed some of those auto-wakeup Maxim interface chips. The original AutoShutdown does not require the charge pump to be running. The AutoShutdownPlus is another story. Incidentally, the stupid computerese naming convention, i.e. running the words together and using capitalization to delineate words, was my idea. I read a rant, er make that editorial from William Safire about how he hated this trend in the English language, so I did my part to piss him off. The AutoShutdown notion itself was not my idea. I don't know if the inventors want their name on usenet, but I do want to make it clear that I only implemented the circuit.
If you were really trendy you would have called it "autoShutDown"

Thanks for helping conserve the planet's supply of space symbols. If we ever run out of space symbols AllTheWordsWouldRunTogether.

Personally, I rather like the idea because it compensates for the writing style currently in fashion at the local multiversity, where everything is in lower case.
