I have the same problem on HP dv6-1308ew. I think the main reason of this problem is something more low-level than OS - hardware or BIOS, because it is also broken on Windows.

On my previous laptop (Acer), I got time estimation working well on both Linux and Windows. When I switched to HP, it doesn't work on neither. Both Windows and Ubuntu showed percent left only (9.10 at the time I switched, and later versions).

Also interesting fact is, that on Acer I had working electric current meter (/sys/class/power_supply/BAT0/current_now), but on HP there is always -1000.

I'm not sure if it is duty of BIOS to report the remaining battery time, but if it is, I suppose this bios doesn't support it. The bios is InsydeH20 EFI or something like that. On Acer I had Phoenix.
