How do I make my laptop power meter reasonably accurately show how much power my battery has left?
When my battery is fully charged on my laptop (Win XP) the battery meter showed nearly 6 hours of life left. Usually I get somewhere around 2.5 hours of use. I’m wondering if there is a way to sync up the battery meter with the actual battery power left. Like measure the amount of time it takes to run it down or something and have the meter recognize that… I dunno. Help!
Charging the laptop fully and then letting it drain almost completely every so often will serve to calibrate the chip in your battery. However the meter itself can still only give you a very rough estimate, as the amount of power your laptop draws fluctuates over time (for instance it’ll draw considerably more while the processor is at full load, or whenever the hard drive spins up).
