Comment 45 for bug 403303

Apologies to Nicholas M at #39 if this appears to be only saying "me too"! Also sincere thanks to Scott Howard at #42 for an excellent explanation.

Scott suggests ensuring that the BIOS is up to date. Nicholas M is using BIOS version 1302 on an Asus eeePC 701 4G. I am using the same model, except it had the original version 0401 BIOS installed. This also exhibits the bug, exactly as reported, but was working in all other respects. Nevertheless, since this is a particularly irritating bug, I wanted to see whether Scott's suggestion would fix it, or have no effect as Nicholas M implies. With some trepidation, I upgraded the BIOS to version 1302 (using the USB key and Alt-F2 method). Following the upgrade, I found it is necessary to switch off and back on, then reset all the BIOS settings, and switch off and on again to get it going. Everything remains in full working order, except that the battery bug is still present. For the record, the OS is fully updated, and running 2.6.32-22-generic-pae #36-Ubuntu SMP Thu Jun 3 23:14:23 UTC 2010 i686 GNU/Linux.

In conclusion, updating the BIOS from version 0401 to 1302 on Asus eeePC 701 4G appears to do no harm, but definitely does not fix the incorrect battery capacity bug.
