Thank you for replying sabrex.
Uninstalling Microsoft ACPI Compliant Control Method Battery and scanning for new hardware did the trick it now charges again. It may have been charging before as it says the battery is 100% but if you unplugged the power it would die and shut down.
While I've been waiting for a reply I decided to buy a new battery because its the original which is 5 years old. Now batteries very in price from £23 to £85. Now I know you only get what you pay for but I wasn't risking £85 just to see if its the battery so I've bought the £23 one. What are you're views on battery prices?
So you are saying the more you have it on charge the more chance of it not retaining the charge? So when this new battery comes and I charge it up are you saying remove from mains and let the battery get used? The thing is when it runs of the battery the screen goes dimmer probaly to save the battery power which I don't like thats one reason its always plugged in. Some laptops have a battery discharge switch but mine doesn't in the sticky (which I can't find at the moment) on here it talks about using an energy wire
do you know what that means?
Now its very strange this happend as there has been no hardware or software update so why did it say plugged in not charging?
Well it appears its another glitch of Vista so thats another one to add to the list.
Thank you very much you you're help sabrex.
