Well I may of solved the rechargeable torch but.
As this will do for most of the time I will want to use it.

OF - you say that you have a UPS for the laptop ....... is that otherwise known as the 'battery'?
Why yes of course.
"The battery inside the UPS.
Actually I never have the battery in my laptop, I only put it in if taking it away from home.
I only ever use it on the mains supply.
I "once" brought a battery for my old HP laptop which was a fair bit over a £100.00
Unfortunately at some early stage I left it on charge getting on for a week and it never worked again on the battery.
Ever since then I always advocate to people that they remove the battery if being used for any prolonged time.
However it's quite possibly that not all laptops may work this way, but I have not come across one yet with all my friends lappy's which probably amounts to 7 or 8 different makes.
(There is a thread/post from some time back outlining this also)
