Which charger (or output) needed for my laptop, related to powermanagment

[Weele]

I need a second charger for my laptop. I use it at 2 locations. At one of these, the laptop is fully charged and works without a charger and at the second location, the laptop is placed a few meters away from me. Connected to an external screen and a hub with other devices.

I don't like to overcharge batteries. If a battery is full, I disconnect chargers. Yeah, I know about the smart charging and that charging will automatic stop when full and so on.

But I place and plug in my laptop somewhere in the afternoon and it stays there for the rest of the day, through the entire evening. So lets say 11 hours. I, and a lot of other people can confirm that in practice it isn't good for the battery to stay connected that long, when fully charged.

So I won't. Because of the work at my first location, I don't want to have a 'lazy' battery and forced to work connected to a charger.

Anyway....this laptop fast charges, so it's full in no-time. I also use heavy program's and games, so the 'battery-usage' slider, is all the way to 'best-performance' and so the battery drains rather quickly. 

Resulting I have to get out of my work 'flow' (or game in the evening), stand up, walk towards the laptop, disconnect the charger, or worse, search and reach for the charging cable and connect it (and because of all the extra hardware I got there, this quite a hassel) and walk back, reposition and resume my work or game. Reason I tell you this so detailed, is because when you are doing my line of work, it is nice to have a certain flow or a fast passed rythem so to say. And everytime doing this totally messes it up.

So I was looking for a charger, which charge the battery as slow as possible. But here's the catch. A few days ago my laptop was 'confused' and said when connecting the charger something about that the charger wasn't compatible and therefore the power/performance something somehting wouldn't work. The notification was gone before I could take it in, so I googled it and this is what I found;

1). This laptop is quite a workbeast and it has systems which monitors and adjust it performance to it's needs.

2). With a low charging power, the battery can NOT be charged when something like a game is running. This is however, not an 'official' statement of HP or intel or whatever.

3). The system which controls the power/performance needs/delivery won't be functional, when the battery is empty and connected to the wrong charger. But also....not officially.

And now I'm about to give up. I spend allready to much time, looking for the answe I need and I just can find it.

I really do want a reeeaaaallllyyy slow charging charger, but is my laptop still compatible as the workbeast it is now? Does it charge when playing a game? Can it handle program's, some internetpages and a few open youtube or vimeo vids AT THE SAME TIME? Because of 'that' system, it can handle it now, even whit low battery when charging. Will this still be the case with the charger I want?

Thank you so much in advance for helping me with this. Because I know my way around the net, but I just can't find anything usefull.

p.s. adjusting the battery-slider to balance the battery a little bit more between performance and life-time, doesn't seem to make that much of a diffrence, when asking a lot of your laptop. So I think that certain system is is actively busy providing what I need, wherever the slider stands. Correct me if I am wrong.

Hi, thank you for your help. It is sadly not the answer I am really looking for. Regarding to what my question actually was, this productsearch comes up with only 2 chargers for my laptop. The 65W and the 90W. I am for sure that ain't right, because the standard charger for this laptop is a 200W. 

So the standard charger wouldn't be compatible and also all the ones between 90W and 200W. That just can't be right.

But if the HP chargers with much less Watts, are compatible and the standard high Watts charger that comes with it, then maybe all the HP chargers are compatible? If so...then also the one with the lowest Watt (45W) from HP will be compatible?

Thank you for your private message.

It seems the 200Watts charger is the only one compatible with my laptop. Yesterday I took the time to look at almost all the HP chargers and most of them aren't compatible with Pavilion laptops and the ones that are, are compatible with various Pavilion CX????, but not CX-mylaptop-.

So from all the chargers HP has, my laptop would only be compatible with a certain 200Watts charger.

To me this sounds really strange. What's so special or diffrent from my HP laptop, than other ones?

Reason I am still going on about this, is that with a (expensive) 200Watts charger, I still have the 'fear' and discomfort I described in my first post.

11 hours fully charged, connected to the charger. Can you maybe ease my mind on that subject, as I don't feel comfortable buying a low Watts charger, while don't knowing if it works.

Thank you again for your message. This helped me.

I hope you don't mind, but I am gonna use a bit of the information you told me, for the chance someone else is looking for a charger and has the fear of overcharging and stuff.

If so, tell me and I will erase this message.

I am concerned with keeping my laptop connected to a charger for about 11 hours and so using needlessly power, as well as a fear of making my battery lazy. Therefore I looked for a very low Watt charger, but this brings a chance of a not working power/performance-need/delivery system.

Read my first post for the enitre story and see if you can relate to it. If so, then Echo-Lake send my the right way to find my (non-satisfying) solution.

Quoting Echo-Lake: To get the answer to this question, As long as you get the correct voltage it wont be a issue, you should be fine. You should get a power supply that has the correct voltage and at least the correct Amps/Watts.

With this information I started looking at the correct Voltage and this is.....impossible to find. 

So I just looked at the original charger and just assume (with back-up intel I'll write down below) this one delivers the only correct voltage.

So the output I am looking for is 19.5V and it kind of stops here.

Because you can't say: I want to use a 45W charger, so (I=P/U => 45/19.5= 2.3) It has to have 2.3 amps to give the required 19.5V. Even if you balance all the combination of amps and watts out, to get the 19.5V, the fact is you can only buy what is offered and here's the catch.

I came across another 'charger-issue' topic. This was really hard for me to understand, because I am no electric engineer and English is not my language. So I am not gonna quote the relative parts. I'll just give you the link.  

https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Backup-AC-Adapter-Not-Charging...

And to make an allready long post, not any longer; It seems that the newer HP laptops have a controller on board which communicate with the charger. This means it won't reconize third-party charger or HP chargers NOT made compatible by HP for exact your laptop.

It's just like your new fast charging smartphone, won't fast charge with your old charger and your cell balancing get's messed up. 

So don't buy a Pavilion compatible charger, if your productcode is NOT listed in the compatiblity list.

The only option I have is to buy the same charger I allready have or go with a lower Watts USB-C charger, which is also compatible. Fact is, the first one is ridiculess expensive and doesn't solve my problem thwe story began with and the second one, the USB-C charger, is no where to be found compatible with my laptop.

It seems that USB-C charging is becoming the next standard, so I wait till this is more common. Then the older 4.5mm charger will likely become more affordable and maybe there will be a compatible USB -C charger.

Edit: Just gave it another look and  for sure the compatibilty storie isn't correct. When I go to HP.nl (I live in the netherlands), where I bought my laptop, there is NO compatible charger. So I litterally couldn't buy an extra charger. Time for me to contact tech.department.
