Recently bought a 7390 latitude (2-3 years old). amazing machine for basic remote desktop and basic office work etc. Battery lasts 10+ hrs on light work.
Had the sleep states turned on and would randomly die at 60% battery while sleeping. Found out its a long standing bug in dells. Sometimes it just restarts the machine so if its in a bag it will just keep running.
Turned of sleep states in firmware and instead now it goes to hibernate on sleep. No random behavior or shutdown.
Its mind boggling this shit used to work totally fine on older laptops, no idea what changed.
- IncRnd 5y agoThe laptops can enter a special standby mode that keeps the network alive, so they will immediately resume when the lid opens. This means, of course, that the laptops never actually shut down and run constantly.
- mnadkvlb 5y agotrue, but i actually turn that explicitly off on physical network settings in windows. My guess is windows will apparently not let u control such things, as the advertising data pipe has to be alive no matter what. Microsft seems to be both google and apple at the same time, selling ads and hardware.
- IncRnd 5y agoI'm really sorry that didn't work for you.
- cma 5y agoHad the same with Apple. An update made it quit sleeping correctly when using a microsd card to expand storage (it worked fine at first).
- x0x0 5y agoMe too. The Yubikey nano -- the little one meant to be permanently left in a usb slot your laptop -- absolutely nukes the battery in my mac, draining it on "sleep" to zero within a day or so. Infuriating incompetence.
- bmurphy1976 5y agoHuh. What version Mac/OSX are you using? I've had a Yubikey Nano plugged into various iterations of a MacBook Pro for years and haven't noticed this. The worst battery killer for me is Firefox.
- x0x0 5y ago10.14, late 2019 16 inch mbp I thought I was being crazy and that maybe something was brushing it, so I let it sit in a moat on my desk immediately after booting. Full battery discharge in sleep in under 30 hours. Without the yubikey, a full weekend sitting on my desk from a full charge leaves a reported 100% of battery.
