Well here`s an update.
Laptop started and has done so for a week or so. Then it decided it wouldn`t start up unless the charger was plugged in. It was fine for a day or two now it wont start at all again. Plugged the charger in again, no lights to say it was charging but left it on over night. Looked at it this morning and both the battery light and the plug light on the front of the machine has mysteriously come on. Pressed the power button with fingers crossed, nothing!!!
Starting to drive me bonkers now. As I have replaced the power jack, rtc battery and battery the only thing left (and I stand to be corrected) I can think of is a faulty power button??? What do you think people? Is it time I introduced it to a very large hammer or am I missing something? Surely if it was a motherboard problem it wouldn`t have started at all, it has started, all be it intermittently.
Thanks 13fontad but I cant do as you suggested regarding configuring the battery because, as I said, the bloomin` thing wont start.
Thanks again for you replies
