Re: How accurate is Laptop's remaining battery life %
You could change the power to 'power saver' would give you lower performance but longer battery life. Alternatively you could download this little gizmo which will give you the exact time you have remaining on the battery.
mioplanet.com/products/batterymeter/ (<< just put www in front of mioplanet)
PS after you have installed wait for the accuracy to reach 3%, after which the times will be displayed.
strangely..my Dell Inspiron shows No battery attached..but even then it gives me a backup of 1 hour...
so i wonder wat would battery life indication mean :)
