its ok to leave your laptop on charge even if theres a full battery, but leaving it on charge for long periods of time can damage the battery. when on charge for long periods the battery slowly forgets whats its full charge state is, hence why most batties wont charge to 100% and may only get upto 95% and then say not charging but if you have damaged the battery due to constant charge then depending on the battery type (li-ion i think) you can fix/improve the battery by simply.... 1. let the laptop fully charge while switched off 2. turn laptop on and leave it to discharge completely on battery (you might have to tell your laptop not to shut down when the battery gets low) 3. then charge to full again with the laptop off 4. repeat if necessary its a good idea to do that once a week my msi cr700 is 5 years old and i still get 2 hours of usage out of it (1h 15m if gaming) just by following what i said. so as long as you let the battery fully discharge the laptop should be fine hope this helps, if any of the details is wrong please let me know and feel free to correct where needed :D On 4 June 2014 14:57, Dan Smith <lug@xxxxxxxxxx> wrote: > I have heard similar things, but then I used to use mine all the time on > charge and not drain the battery fully and then had to replace the battery 3 > years after I got the machine. > > However having just looked on PC World's website, it says not to squeeze > every last bit of juice out of it alongside other things to help keep the > battery in good shape. > > http://www.pcworld.com/article/191574/long_live_your_laptop_battery.html?page=2 > > Hope this helps, although someone may want to confirm this fully. > > Regards > > Dan S > > On 04/06/14 14:51, Neil Winchurst wrote: >> >> I have a desktop computer which is the main one for me.
