Hi all.

I have a Dell P28F laptop, bought about a year ago.

To date it has been working pretty faultlessly.

However, I disconnected it from mains power to show something to a workmate and it shut down instantly. This is something I do regularly but the shutdown has never happened before.

I rebooted (on mains power) and it booted up with a message telling me my battery was flat, something I knew couldn't be the case. I shut down, removed and replaced the battery and now it said I had 100% battery power, but unplugging the mains power caused an instant shutdown.

I am backing up now, preparing for a disaster and I noticed the battery light was alternating between red and white. It is now a dull white glimmer.

Any thoughts?

Regards

Pat Clarke
