    I have ordered my new laptop, hope fully it will be arriving tomorrow.

    I am looking for advice as to how to look after the laptop battery if I use this laptop everyday in the office and then take it home.

    Should I have the laptop plugged in all the time?
    Or should I run it from the battery first until it starts asking to plug it in and continue to work with it plugged in?

    I have never worked with a laptop for everyday use. I have always used the laptop when out of the office and then used the desktop in the office.

    I was under the impression that if you left the laptop plugged in all the time it damages the battery and you end up with it never holding its charge.

    In the "Easy Settings" program that comes loaded on the laptop, there is an option called "Battery Life Extender", which when turned on, won't charge the battery unless the charge level drops below 80%.

    So, if you leave it on the AC power supply all day, it won't overcharge the battery.

    Since Li-ion batteries have a finite number of recharge cycles, you probably don't want to run it on the battery unless you need to.

    I wold add that the BLE also doesn't charge the battery above 80% so it keeps clear of the zone (90%+ charging) where most damage occurs to the chemistry during the final top-up. The computer does not keep topping up the battery once it has reached the required charge. Also, it is advisable to avoid regularly fully draining the battery although this may need to be done every 6 months or so as part of the battery recalibration. Lithium batteries are not like the nickel ones which benefit from regular full depletion.

    Does this setting also stop charging the battery above 80% when the laptop is off but still plugged in?

    Yes. If left continuously plugged in the charge will slowly drop a few per cent until a top-up to 80% is initiated. However, if you disconnect / reconnect the mains power any top-up will immediately happen.

    I have been using my 900X3A for 18 months this way and battery wear is only at 6.35%. The BLE is a great feature
