Laptop battery issue

I'm pretty sure the E1505 has "speed step" on it. Double checkthe speed step settings to make sure they are set for long battery life, maybe it's somehow reset itself?

 

Laptop battery issue

I did check it out and already had it disabled so enabled and still no battery showing up in the bios. I guess I'll be taking it apart

 

New battery not charging

I suggested uninstall, not re-install.

There's an extended version of those instructions - the same idea, but some additional steps.
Shut down hte machine
Remove the battery - run on AC power only
Device Manager > Batteries
Uninstall Microsoft ACPI-Compliant Control Method Battery
Shut down the machine

Remove AC power
Wait 1 minte
Insert Battery
Connect AC power
Start the machine

Microsoft ACPI-Compliant Control Method Battery should be reinstalled when the machine is booting

But, the .3 volts might be significant - I agree with Kbird
