Dell Latitude C640 laptop when not power on when using ac adapter!
When I remove the adapter the machine will power on with the battery show bios screen bootup then die because of low battery charge!
Will not do anything when using ac adapter all you see is a rapid blinking orange light!
I tried another ac adapter with the same results so thinking it may be the battery!
Thanks,
