On the whole this is a good machine, but it uses the so called “Modern Sleep” or "Modern Suspend" which I don’t like at all.
I would like to switch back to S3 in the BIOS, but get the dire warning about needing to completely reinstall the operating system. I like to leave the machine in sleep rather than powering off and then on again.
Can I ask if others have done this, and whether they found it worked without problems?
There’s a useful post on this forum: viewtopic.php?f=83&t=134156 which warns that you could have trouble. I also found this excellent post from a T14 gen 2 user who says he is not having trouble having switched to S3. https://www.reddit.com/r/thinkpad/comme ... _t14_gen2/
More on why I dislike modern sleep:
First, like the others in the forum posts, I don’t like feeling I have no control on what the Thinkpad is doing when supposedly in sleep – see tales of hot laptops in carry bags!
Also important: I have measured the power consumption of my T14 when in sleep. If in stand alone the consumption jumps around dependent on what it is doing, but the average consumption is about 5 watts. That compares with less than a watt for my old T440s – little more then when powered off but plugged in, provided the battery is charged. But I mostly operate now plugged into a USB-C dock. Here the power averages more like 10-11 watts. Some of that will be the dock. But over a year a very rough estimate says that if mostly leave the machine in sleep when not in use I will use about 60kWH per year – cost c. £UK£18. Not insignificant, and not good for the environment.
Reason: Fixed title per OP's comment
This forum post suggests editing the registry, but I haven't done that. https://appuals.com/disable-modern-standby-windows/
I really think Modern Sleep is of questionable benefit for most. It is poorly implemented. It wastes power, results in overheated laptops in bags etc. Recovery from sleep seems to takes about the same time as before - so where is the benefit? It should be possible to easily switch it on and off.
This forum used to be one of the reasons to use Thinkpads, with the huge amounts of help available.
But I guess it has maybe been superceeded by the Lenovo Support forums? https://forums.lenovo.com/t5/ThinkPad-T ... -p/tp01_en They don't seem like anything like the value that this forum used to be!

Also the seemingly downhill direction of W11 may have something to do with the aversion against newer models.
Lenovo: X240, X250, T440p, M900 Tiny (all with W7/SP1 and NO updates since 2018).
