Hi<br>
<br>
I am trying to get round a problem with ThinkPad R31 running XP and Ubuntu 10.10<br>
<br>
The battery is a bit flakey and it doesnt always show the correct time 
left, so the light will flash telling me it is running out of battery 
but it will run for about 60 mins doing this. Not a huge problem but I 
have bigger problems in Ubuntu.<br>
<br>
It will not run off battery. If I boot it on battery once it gets into 
Ubuntu it will hang and the scroll lock and caps lock light flash. Also 
if I boot on AC adapter and then pull it out it does the same.<br>
<br>
It doesnt do this in XP. So while the battery is a bit flakey this is more of a problem with Ubuntu specifically.<br>
<br>
I have tried editing the boot options in grub - adding acpi=off - but 
that stopped the machine booting. It just showed a load of text of 
screen and wouldnt go any further. I managed to remove the line and 
restored grub.<br clear="all"><br>
I really would love to resolve this. It is the one thing stopping me from using Ubuntu all the time. <br>
<br>
Any ideas?<br>
