May I ask everyone for further help as this did not work - I did as you said but still at exactly 26% left it shut off without warning and I had to recharge it but this time I did it differently!
I have been charging it until the blue light comes on and this says 100% charged but also says 3hrs 30mins. It only takes 90mins for this to happen which seems a short time.
This time, once it had charged 'fully' I left it on charge for another 2 hours and it then still said 100% charged but....it now says 6 hours!
As I write this it shows 77% and 2hrs 30 left. So do you think that as I had set the low battery warning at 15% it just switched off because it showed 25% but the number was incorrect?
I do not mind buying a new battery (the laptop is 4 years old but not used for a year) but it is integral and to change it I would have to remove the back screws and at 80 yrs I do not know how easy this will be.
Any further advice please?
