hii have a sony laptop and the battery is TERRIBLE lasting at most 30 mins. at uni and will use the laptop in lectures etc i will need to be able to use laptop without it being plugged in. i have been told that you can get external batteries that will last like 4 or so hours. does anyone recomend one?thanks
Change your power management profile, decrease the scren brightness, disable wifi if not using it.loads of things. Vista at full speed uses my battery in like 40/45 mins just sitting on the desktop, can stretch it out to like 3 hours at most. Google 4 an external battery if u really need one
it really all depends on the type of laptop you have. since you have the sony laptop, check out the sony website and see what is recommended for your laptop. som batteries will work, others won't.
yea those external batteries work try it
