Battery as is found in D810 series (and other) laptop. Battery light on laptop started flashing 4 times orange and once green in rapid succession. Pulled the battery and it flashes lights 1, 3, and 5 when checking the charge amount. The health indicator shows that it has less than 60% max capacity left. Anyone ever try troubleshooting these battery packs?

Pack voltage is 11.6V discharged and evenly distributed across the series cells.

as you arnt on...

Ive never seen that on mine. And how the hell did you tell the 60% and the 11.6discharge bit?

Hold down the power indicator, it'll blink and show a number of LEDs lit up as shown in the manual. The more LEDs lit, the higher the batter wear. 5 LEDs is over 60% wear.

The battery was dead when it decided to crap, since then I've pried the case apart and removed the 9-cell pack and electronics so I could save the weight while I try to diagnose the problem.

I pulled the battery out, then I separated the battery's case and it has 9 cells and control electronics. The case has been replaced in the laptop to fill the void (it has a foot).
