Any way / software to check how long laptop battery can last without waiting for it to drain
Posted on 2012-12-24
My corporate office has one Lenovo X220 but nobody knows if it's
been used for how long by the previous owner. They also offer
Dell E6230 laptops.
I'm choosing between one of the two but first I need to know
how long the battery will last (as previous owner(s) had used them
Windows 7 power meter usually doesn't give a good gauge.
Is there any tool / software that I can install to gauge for the
laptop I'm going to choose/collect, how long the battery will
last on full charge?
Assuming it's brand new standard battery (6 cell ?) for both
X220 & the Dell E6230, which of them would last longer?
