Battery Status Light flashes orange WHILE the AC is plugged in

The battery is bad and must be replaced.

When battery capacity reach the minimum level it flashes orange to warn for sudden collapse of battery voltage - hence abrupt black-out in the bytes pump.

A full cycle charge - preferably with the highest capacity charger (so the laptop can be powered also in the meanwhile) for a normal battery will turn the flashing light into green charging. (color depends on the model)

When the light stays orange even while charging and the battery is more than a year old it's prolly just worn out and ready for replacement.

A worn out battery won't charge. This easily measured with a power meter when the laptop is turned off with AC adapter connected.
Power consumption is nearly zero in this case. A healthy and empty battery will cause the AC adapter to go on full power.

Thanks for the prompt reply. I will replace the battery. I had suspected that was probably the problem but was confused by the fact that when I hovered over the notification icon for power, it says the battery is 100% charged. But I just noticed that I get the same indication on my Dell Precision T5500 which doesn't even have a battery. Doh!

Many Laptops have a reserve battery that is for keeping the clock/cmos/hybernate active while the battery is being changed.

I have the same exact problem with my E1705 ....... the light blinks orange when plugged in and according to the manual this should occur when the laptop is operating on battery power.   Did you make a final determination and if so what was the fix.

I don't want to buy a battery and it is actually something else.

TIA for your help !!!

I replaced the battery and the problem went away.
