> [@Burt](#): > > A good healthy discussion. Please take my comments as just that, just getting closer to the problem/solution. …hopefully my aiding clarity not trying to split hairs the following comments… Not at all health discourse here! 🙂 1. I removed my ML1220 and tested this before posting. Machine will not boot until AC powered with the battery removed. 2. Looking at my historical CMOS batteries life expectancy with relation to their capacity the FW is using a lot more power. I have a CR2032 (240mAh) from 2009 still doing it’s job… 3. Not researched yet either, I based it on [npr’s post here](http://community.frame.work/t/viability-of-an-ml-1220-rechargable-battery-for-rtc-cmos/17664/43). 4. I’m not sure. Might have to join other forums for laptops with the ML1220 and ask lol. I think you are testing your used case and that is a valid test to run! I’m debating running a month long test but I would like to wait for BIOS 3.09 so i can also see how shutdown power usage has improved. I know 3.08 is floating about but I’m unsure what is and isn’t changed in that release. --- _[View the full topic](https://community.frame.work/t/laptop-wont-power-on-unless-i-plug-in-ac-power/13085)._
