Thanks No, you never know. Not the same case, but my Motorola mobile phone (means Lenovo) has developed a new feature after two years of use. Since the beginning it had some "clever" battery management. If left connected to the charger all night, it would charge to 80%, stay there, and go to 100% just in time for the alarm. Now it has changed behaviour: it charges to 80% and stays. Once every few days, it charges to 100% to maintain calibration, it says. Of course, the control hardware was there from the start, but what they did with it changed. And another phone from the same brand, very similar but one year younger charges to 100%. My old and small Lenovo laptop (Yoga 30011IBR) can limit the charge to about 80% with a Windows application from the manufacturer. The tool does many things, and one of them is configure the charge limit. Interestingly, if I boot to Linux the limit holds, till one day randomly it goes to 100%. My newer laptop, Lenovo ThinkPad L14 Gen 3, has never booted Windows, but it has a generic daemon that knows how to handle the power limit. There is a generic configuration file, and works perfectly (the limit applies even if the machine is not booted). I actually bought the thing with a larger battery to compensate. I mention this because generic applications to control charge must be possible also in Windows. -- Cheers, Carlos.

I mention this because generic applications to control charge must be possible also in Windows. > > The scheme isn't all that mysterious. There are two parts to charging. CC and CV. The CC (Constant Current part), charges to somewhere around 80%. The CV (Constant Voltage part), charges the rest of the way, and as the constant voltage is applied, the current that flows into the battery declines with time. When the current flow is down to 3-5% or so of the CC value, the battery is considered "full". Because the cell is held at the high voltage (4.2V maybe), this is hard on the cell, and the choice of "fullness" is a compromise (since each 100% charge cycle stresses the battery a tiny bit). Charging and using just the first phase (CC), the "end voltage" is the CV value. The cell is only at that voltage for a short time. If no other charging occurs (the MOSFET disconnects from the pack), then the voltage across the cell "relaxes" as normal and heads back to 3.7V . The charger knows, via a state machine, it has completed CC and is entering CV. If instead, the state machine heads back to "idle" state, the pack is now charged to 80%. This means, to a large extent, the charge controller already has all the ingredients for the behavior, it just needs a controllable state path to "idle", controlled by a "only charge to 80%" bit in a register. If the bit is set, the charging stops after CC completes. Using Constant Current, protects the charge controller. An infinite current would flow, if the battery was really flat and the controller was applying a relatively high voltage. By using a Constant Current circuit, just the desired current flows, maybe a current high enough to support "fast charging". The charging behavior in BEVs shares some similarities, but the values applied are modulated by the measured conditions at the pack (like pack temperature). Some cars, like the IONIQ 5, they're a bit closer to a laptop curve, while some of the Teslas have a peak at maybe 30-40% or so, and the charging level isn't all that constant. The laptop charger on the other hand, is generally well behaved, so the electrical settings don't really change during CC, and later during CV. Paul

The tool in Linux is called "tlp" (https://linrunner.de/tlp/). There is a list of supported vendors. But they rely on support from the kernel, which are different guys. Windows could do the same if they (M$) wanted. -- Cheers, Carlos.

I noticed the battery level was at 100% subsequently. I remembered, during setup a few years ago, being warned that I should set a max battery level to 60% (or was it 80%) to extend battery life. I wasted a half hour or so looking for the place to reestablish that setting but never found it. So it's not only HP that has this problem. Let's hope someone in this thread knows where to voice the magic incantation. -- Jeff Barnett

Unless this is some kind of ransomware, what kind of software
deletes partitions for fun ???
I don't think I've seen any behavior like that here.

An application like TestDisk can restore partition table entries.
This assumes no lengthy (two hour) erasure writes were done to the disk
by the malevolent software.

The problem with TestDisk, is it easily picks up phantom file system
headers. I had it recover a disk properly, only one time. It is a fine
idea, but I don't know if it has been fixed up yet or not. It can make
mistakes, like have partitions overlapping when it is finished.
You can also have damage to disks, where the partitions are still intact,
but the content inside is scrambled. There is at least one freebie for NTFS,
that can recover files in that case. Again, it all depends on the kind of
damage, as to what can be recovered. To use that kind of recovery
software, the partition has to have known boundaries.
The application Photorec can recover data, but there is an assumption
the disk is not too fragmented. As without directory information,
it is pretty hard to "glue" pieces of files back together. And if
you've ever had a tool recover fragments with no file names,
you'll know what Hell is like. I had a returned result once,
of 100,000 fragments from a scan, each fragment really tiny, and no idea
how the pieces fit together. Like a giant puzzle with no "hints"
to aid in reassembly. I couldn't do anything with that.
There are cases that recover well, like some of the cases that
Recuva handles (accidental erasure in the Trash bin). But at least
for accidental erasure incidents, the structures of the disk are
fully intact, which is why the recovery can be pretty good.
