Inspiron 5758 - Adapter becomes Unknown in BIOS and will not charge battery
I have an Inspiron 5758 that's about 18 months old. In November I noticed the battery was no longer charging. I replaced the battery and then the adapter with a genuine Dell part. Now the batteries are both dead and will not charge. I have flashing orange LED as well.
On the BIOS screen the AC Adapter is shown as "Unknown" when it is the Dell supplied adapter (or a Dell purchased replacement).
