Thanks for reply. I wasn't aware of this feature and it's definitely of interest (if not a must have really).
Also to add, about the laptop bit, another couple of things:
- Lenovo battery utility comes with a few options, one of which is change charge thresholds to try to "Optimize for battery lifespan". Not sure if it fully works, but for what it's worth
- also one final big one, it's BIOS set-able to "power the laptop on when AC power is attached". Something I've found missing from a lot of laptops vs their desktop cousins, is the ability to "restore PC powered up state as it was prior to power cut". ie when a laptop looses AC power, and it's battery depletes, and Windows does it's either go to hibernate (or let to run through to nothing), it won't ever come back on when power is finally restored
