Well, the battery life can now be improved in two ways:
- Upgrade the BIOS to 0601 (make sure the Eee is connected to the Net e.g. via a wireless network, make sure it's plugged into the mains, go to the Settings tab, Add/Remove Software, Settings tab, against BIOS Updates click Open, find the version 0601 which says "Updated all battery discharge tables to extend battery life" and click its Install button, it'll need to restart to do the update. Don't touch it while it's updating - and using it on the mains will ensure it doesn't switch off in the middle of the update which could kill your Eee).
- Get the higher capacity battery, which is now available. To get your hands on one:
- buy a high capacity battery from an Asus reseller for under £30 plus postage, as a spare, or
- return your original battery to Asus for a swap, which will cost you £10 for the battery plus the postage costs of sending your existing battery to them (or you could buy a spare and swap your original!).
1. Extra battery
They might run out soon but at the moment there are still a few black Eee 5800 mAh batteries at Ebuyer. There are other UK Asus resellers but I don't know what their stock position is.
2. Battery swapThe process is a bit involved. To save you time hanging on the phone with Asus support (I spent at least 20 minutes on hold), here's what you can do (at the moment, anyway, unless Asus go and change the procedures again!):
- Go to the Asus EeePC 900 battery swap web page.
- Fill in your details and submit the form (you'll need the serial number of your EeePC900 from the bottom of the computer, see the screenshot above).
- Wait for them to send you an email with RMA number (return number) for your Eee, with packing instructions and address details for their agent A-novo; it may take you a few days before you get the email (chase them if you've not heard after a week), and I'd send it recorded delivery myself. If you need to call Asus to chase or check stuff, rather than donating still more of your hard-earned dosh to them by your being kept on hold for ages on an 0870 number, you can try their landline 01442 202700 (press 2 to get their support line) which unlike 0870 numbers are at least included in your inclusive minutes, if you call from a mobile phone and have that kind of package.
- After they get your battery A-novo will send you the replacement bigger battery; at the moment they'll meet the costs of delivering it to you but you'll be charged £10 for the replacement; again, it may take them some days or a week or two to do it.
