How to preserve an old laptop?

Little backstory first to explain the situation

I have an over 10 years old pc with ssd(samsung evo)that I rarely use(maybe once a year)
After a long period of time the pc is off,when I turn it on,it takes an extremely long time to load the os(it's like you are loading windows from a floppy drive,it usually takes half a day to load the os)
Once windows finally loads and after few restarts(only the first load is extremely slow),the pc starts to work normally as if it was not off for a very long time
The next time I leave it for such a long time,I will encounter the same problem

Now on the the laptop.
The battery is connected and it gets drained very slowly(it can last maybe two months without charge)
Does keeping the battery on also gives some voltages to the ssd or no power is sended to it(I think this is what is causing the problem on the pc)
Does just charging the battery maybe once a month without turning the laptop on keeps it from getting the problem I have with the pc or I have to turn it on periodically

You are likely experiencing bit-rot on the SSD where cells loose their charge and it takes longer to read data from those cells. This happens when a cell has not been written to for a long time.

Keeping the battery charged and/or turning on the laptop will not correct the situation.

Two possibilities that you may consider doing every 6-18 months are:
1. run DiskFresh on the drive. It will read and rewrite every sector.
2. Take an image backup of the drive, then do a full restore where all the data is written back to the drive.

Ps. I the laptop is important to you then there should be an image backup just in case it fails to boot at some point.

It is just Windows updates and maintenance tasks, these will take a long time if you leave a PC/Laptop off for long periods of time. Just a rinse and repeat the next time.

There is no problem with either.

Batteries have a self discharge, and a slowly decreasing full charge capacity, that's how they are.

Exactly this all missed tasks are run at startup, also installing new updates.
A few friends that uses there laptop once a month have this issue also in some degree. After bootup is is about 2hours slow, after that a reboot and machine is slow. After i told them it has to do with missed task, that are goign to run, they now just turn on the machine once a week for a few hours, let it do its thing and then shut it down again. Then the next time they want to use the machine, it is ready to go. Had no complaints anymore.

The battery hasn’t been changed in 10 years?
