I like to be able to turn off display while lid is open because it's a bright display and the TV is 5 feet in front of me...

You still have the 'turn off display after...' option? If so, set it to something short.

1 modern standby

It is easy to find out. In any Command prompt or PowerShell window, enter

Code:

powercfg -a

- Only a computer with 'modern standby' has this in its results
Standby (S0 Low Power Idle)
- Computers with traditional power management would include this
Standby (S3)
instead.

2 log-on screen

Check Settings, Personalisation, Lock screen, Screen saver settings [in green, right at the bottom] to make sure you have not set the checkbox for On resume, display log-on screen.

3 Time on battery

- That does not sound bad for a 17inch screen.
- You could check your manual, the HP support site & the HP user forums to find out if this is normal or not.
- Unless your battery is fitted internally, you can get a spare so you can swap them around if you expect to be on the move for longer.
- My main computer has an internal battery so swapping is not easy. I have bought 'powerbanks' [big external batteries] that deliver the 20V input that the computer needs. One is from Dell and the other is from PowerOak / MaxOak. These things are not as cheap as standard computer batteries and I only bothered because of the limitation of having an internal battery.

4 Battery care

- My computers are kept plugged in & fully charged all the time except when I have no choice [which happens rarely]. Their batteries have not suffered at all.
- I adopted this policy a few years ago and every computer battery has retained its then state of health [i.e. the amount of charge it can hold].
- Batteries have an expected life expressed as a number of full charge-discharge cycles. If HP have not clearly stated that in their manual, get on to HP support and ask them.
- 'Cycling the battery' & 'draining down' the battery just uses up part of its life. There is no evidence that 'cycling the battery' or 'draining down' achieve any benefit with modern batteries.
- For further info, check your manual, the HP support site & the HP user forums
- Many people still retain knowledge of battery technologies that became obsolete more than a decade ago. So if anybody gives you battery advice, ask them for evidence. That's the only way of avoiding the trap of acquiring obsolete knowledge yourself [such as the supposed merits of 'draining down'].

5 Misc

- Check your manual.
- Search HP support. Ask HP support.
- Search the HP user forums. Ask in the HP user forums.

6 Jealousy
I have a Dell Inspiron 7779, a 17inch laptop with a touchscreen. Does your HP Envy 17t-ce000 also have a touchscreen?
- The details I found were for HP ENVY - 17-ce0015nr which might not be the same. It is very roughly an equivalent of mine.
- The HP ENVY - 17-ce0015nr is not on sale in the UK. I wanted an HP but was forced to buy a Dell because I was keen to try out a large touchscreen laptop.

hello there,

hope you are doing fine.

first of all, thank you for providing such valuable info. I actually wanted to ask you more about battery care.

Actually, I just recently bought a surface for note-taking purpose as I am uni student. I use it almost 12-15 hrs a day for taking notes and I can keep it plugged in all the time if I want. Replacing the battery on this thing (surface pro x) is not that easy and that is why I want to prolong its battery life as much as possible. I asked the same question on reddit too and the info i got there was to keep cycling my SPX on 20-90, calibrating its battery once a month and few other very detailed instructions (which were optional). The guy who posted all this seemed to be very knowledgeable and currently uses the SPX and has used portable surface tablets in the past too. he reported that using the techniques mentioned above he was able to have almost 0-1% wear on his SPX after using it for a couple of months. He was also using a very debloated version of Windows but nonetheless, the charging techniques were the same

Knowing all this and from your knowledge, what do you think would be better to get the best possible life out of the battery,
using the method I mentioned above or keeping it plugged in at all times?

Btw I also have an HP laptop which is now 4 years old (so has a very worn-out battery) and I also wanted to know what'd be best for it battery care wise?

any help will be much appreciated. Thanks

See my recent post in another thread.

In short, I normally keep my batteries at 100% whenever I can.
I'm conducting an experiment on one computer for which I'd been keeping very detailed battery notes. I only allow that to charge to 80-90% and intend to keep doing so until at least mid-2023 by which time I hope to be able to see whether its gradual degradation has altered at all.

thanks a lot for the quick reply man!! really appreciate it

so you think my best bet would be to keep it plugged in whenever I can even on 100%?
that said, I do know that nobody knows completely how each battery works and best we can do is conduct experiments which you are already doing and have done a lot of so kudos on that!!

thanks again!!

That's what I have always done.

I do not think anybody knows the correct answer. I don't even know if my protracted experiment will produce definitive results.

My laptops give me the option to charge to 80% maximum when plugged in - so that's my preference/recommendation if you have that option and will be leaving it plugged in for extended durations.

saadsaleheen · 24 Jan 2022

Which laptop do u hv btw if u don't mind me asking

steve108 · 24 Jan 2022

If seen this option on Dell and Asus laptops - may be offered on others.

Steve,

Another user reported last year that the reduced-charging option was not provided in a recent version of the Dell Power manager utility or in their Bios. I had a look at the updated versions of that utility for a couple of other Dell models and the facility had also been removed from them. And Dell support issued a video in which they stated that leaving a battery charged to 100% would not make any difference to its useful life.
For a link to the Dell video, see my recent post in another thread.

I'm uncertain about the whole issue so, in the absence of any publicly available evidence [as opposed to claims], I'm generating my own evidence. I have good records of battery degradation [Last charged capacity / Design capacity] for the two batteries I use in my main computer [Dell Inspiron 7779] so I'm spending two years limiting their charge to 80-90% of their maximum. My experiment has only been running for seven months so far but I'm keeping my fingers crossed that two years worth of records might reveal a pattern. If not, I'll just have to continue with the experiment.

My problem with the whole topic is that nobody has published battery degradation data for the complete battery systems [battery materials together with the battery management systems that control them].

Thought you'd be interested,
All the best,
Denis

I agree, it's just gut instinct based on what I've read that I would not to inflate the balloon to 100% if the PC supports it.

My Dell is around 5 years old and the Asus laptops I'm referring to are about 2 years old that support charging to less than 100%.
