Cadbury's choccies to the person that can assist!
My sister's laptop has developed a fault...it keeps displaying the following message when booting up:
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
Her laptop runs very slowly and does not charge the battery because it's running off reduced power.
I've been advised that a bios update will resolve the problem but I'm unable to do this because the battery has less than 10% charge.
I'd be very grateful if I could try out your battery and charger at your house to rule out a problem with my battery or charger first.
