Laptop brand that lets you disable the battery through BIOS settings ?

[knowledge2121]

I want to buy a laptop that lets me disable the battery when I have it stationary and connected to an external monitor at home....and also lets me turn the battery on when I want to take out the laptop with me...

Are there any particular brands or models ? it should also meet the following requirements:

0) i5-8250U or i7-8550U
1) it should be easy to replace/install the laptop components...
2) RAM is upgradable to 16 GB
3) one M.2 + one SATA3 slots for SSD..
4) No Optimus

No. I've never heard of this being a "feature" why would you even want to do that?

Normally if you plug it into the docking station it will recharge the battery then move over to docking station power directly and not drain from the battery. So if your concern is about over charging and reducing battery life. Nowadays that isnt much of an issue. Newer chips are way better then they use to be in the past.

so constantly having the AC connected doesn't damage the battery ? lets say for weeks... ? maybe months ?

With new tech, nowadays. No it shouldn't. Newer chipsets are getting smarter and smarter, we are at the point where it has very little effect on the battery due to smarter chips.

I don't understand how smart chips would help battery health ? I guess you mean battery tech ?

No. There is actually a chip on the battery that controls when it needs to be charged and monitors the decharge etc... the new chips are way more efficient and accurate when giving its results to the PC to tell it when to charge, decharge and stop charging etc...

It reduces the waste. Unlike older chips and tech it use to just continously charge the battery which would result in over charging or it would get to 100% and discharge and recharge between 99%-100% over and over further reducing battery life. The new chipsets resolve most of those issues.

So will this chip be able to control the charging when the laptop is turned off, suspended or hibernated with AC connected ?

Yes since the chip is on the battery it's self.

So the chip stays active even when the laptop is turned off interesting...

As long as the PC is connected to a power source, or the battery has juice, it should remain on and be able to perform its function.

So all laptops with an i5-8250U and i7-8550U have this chip on their batteries ? or are there specific brands ? would you recommend a brand ?

I also have a DELL inspiron 7567 ... does it have this functionality ?

And the functionality is OS independent right ? doesn't matter if you run windows or linux .. right ?


Many Thanks

Its not OS dependent. Its a hardware chip built into the battery. I would suspect anything newer then 2008 has this tech. I believe that laptop should have it as well.

It's always advancing in tech so newer devices may have more efficient chipsets.

thank you so much for your help...

have a nice day.
