Over the last three weeks my laptop started to turn itself off every few days even though I still had at least 10% battery. Its now happening everyday and has crashed both this morning and this evening. When I plug the power cable in it seems to be okay. One time I had 28% battery left! Any ideas? thanks
Could be a "Power Option" setting - go into Control Panel - Power Options - look at left hand pane - "Choose when the computer sleeps" OR "Choose when to turn off the Display" - you need to lengthen the time.
Thanks northumbria61, I have changed the "when computer sleeps to 1 hr" to see if that solves the problem, it was on 15 minutes. However, I don't think its only slepping as it starts up with black screen asking if I should start up in safe mode, obviously I do start up in safe mode.
thanks Graham, I have gone into power options, seen the following options for battery; Critical battery action Low battery level Critical battery level Low battery notification
Didnt see anything relating to shutdown at x% power. What is this option under?
Also from your advise I have looked at the battery and it is a Li-Lon battery so I assume as my laptop is now 2 years old I should keep the charge at 40% or above if I understand the instructions correctly?
According to the link, this is for MI-NH cells not the Li-ion Battery. It states; As the Li-Ion batteries are chemical in nature, charging and recharging is not going to fix the problem once the chemical reactions stop happening. Therefore the best advice for re-calibrating the Li-Ion batteries is to store the battery at 40% charge if it kept unused for any unlimited period of time. Also don’t leave the battery in the laptop if you don’t use the battery or if you plug the laptop into outlet power.
So should I continue to keep the battery charged over 40% then? Get your point about the meter reading. Thanks for your time Graham
