Windows 10: Heavy battery loss on sleep and Hibernation mode - Windows 11

HiI have recently got this laptop from HP with windows 11 the laptop has a peculiar problem of battery drain on sleep mode. the laptop loses almost 20 percent battery in 8 hours of night and at times you cannot even boot the laptop because it has reached to reserve battery levels, and you need to search for power adapter. searched online for help which recommended changing sleep to hibernation. did that as well but the outcome has no change.the only solution that works is to shut down the laptop every time you don't use and that is not a solution if you want to resume your work. please suggest

:)

 

Battery drain in sleep and hibernation

Since a clean installation of Win 10 my laptop battery has begun to completely drain overnight when in sleep or hibernate modes. It is ok when powered off so I suspect the battery is ok.

Any suggestions?

 

Battery drain in hibernation

This is a volunteers forum. We cannot fix anything for you!

I would start by taking these steps:

1. Put Windows into hibernation.
2. Get it out of hibernation.
3. Check the time stamp of the hidden file C:\Hiberfil.sys. Does it reflect the time when you took Step 1 above? If it does not then the machine was not in hibernation.
4. Before going to bed, make a note of the battery charge.
5. Switch the machine off and unplug the power cord.
6. Next morning, before plugging in the power cord but after turning it on, make another note of the battery charge. If there is a noticeable discharge then you have a leaky battery or a problem with the motherboard. Windows can't be the culprit because it
   was off all night.

 

Hibernate mode Vs Sleep Vs Hybrid sleep.

Make sure your batteries are good. They need to be regularly replaced every 3 - 5 years. Weak batteries make for an unreliable UPS. *Frown But new batteries are cheaper than a whole new UPS.

Totally disagree with that! No way sleep affects performance. As for stability, on rare occasions, a computer will not properly come out of sleep. Typically a simple reboot resolves that. But once a computer boots properly, sleep mode does not interfere.

Sleep mode is nothing new. Microsoft and the applicable hardware makers have had over 20 years to sort problems out.

Sorry, but that makes no sense. First, hibernation was indeed developed for notebooks - so when you close the lid, you can resume exactly where you left off. Yes, you can use hibernation with a PC and you can use hybrid mode on a notebook But hybrid mode was developed for the PC.

Second, if a user suffers from frequent blackouts they should definitely be using a good UPS with AVR. Note I've lived in Tornado Alley for the last 28 years so I have some experience with that. But more importantly, if a user suffers from frequent blackouts and they don't use an UPS, they should be saving their work and "gracefully" shutdown the computer, not put it in sleep mode.

Lastly, hybrid mode is called hybrid mode because it is just that, a mixture of modes. In hybrid mode, data stays in RAM (in a low voltage state) for faster wake times. But in hybrid mode, a full hibernation file is also created in case the user (or Mother Nature) decides to remove power completely.

Newer versions of Windows are not XP. So true, there is no need to reboot Windows just because it has been awhile since the last reboot. I only reboot my 6 W10 systems when some Windows Update or security program update requires it.

Memory leaks should not be part of this discussion. Those are faults and exceptions, and very rare. Exceptions don't make the rule. If a program is that buggy, get rid of the program.

As for things left in memory, as I noted above data is indeed left in memory to speed up wake times from sleep mode. Remember, unless you unplug the computer from the wall (or flip the master power switch on the back of the PSU - if it has one) your PC is in "Standby mode" and +5Vsb standby voltage is being distributed to multiple points across the motherboard.

If you terminate a program, that memory space is freed up. But if you keep, for example, a Word document open and allow your computer to sleep, some of that data will be retained in RAM for quicker wakes.
