    I just got my Series 7 Chronos after two HPs in 5.5 years breaking down. I love it but it has an embedded battery, I think its LiPo. Is it OK to keep it plugged in at all times, as I usually do except when i take it somewhere, or should it normally be unplugged? Should I cycle the battery?

    Do not deliberately cycle the battery except for doing the battery calibration in the BIOS every 6 months or so. Unless you need to use the full capacity of the battery then enable Battery Life Extender in (Easy) Settings. This limits the charging to 80% of capacity and reduces the wear on the battery.

    Yes, leave it plugged in but enable Battery Life Extender. Notebook manufacturers have become cleverer about the charge management and squeezing in the last part of the charge into the battery is what causes much of the wear. Hence Samsung's introduction of BLE.

    What does it mean exactly? The battery will charge until 80% and then it will stay at 80% until you unplug?

    When BLE is enabled the battery will charge to 80% and charging will then stop. The charge level will slowly drop (say 0.5% per day). If the mains power is left plugged in the battery will not get a top-up charge until the drop is several %. If, however, the mains power is disconnected / reconnected then a top-up charge happens immediately. You can, if you want, further reduce the frequency of top-up charges by temporarily disabling BLE, letting the battery charge to 90%, then re-enabling BLE. Keep away from charging above 90% unless you need to have the maximum battery capacity available.

    Thank you, now I understand. Your last advise makes me curious: why should I not charge over 90%?

    Squeezing the last part of the charge into the battery is said to be one of the main causes of wear of this type of battery. That's also the reason why the charge rate automatically becomes very low.
