What size barrel jack is this?

[evilkitty]

I want to adapt this plug

to this socket


some time back i got a replacement charger for my laptop, i fixed the original, and this laptop uses the same power spec on a different jack size, so rather than buying a adapter i can just buy a adapter jack

That looks like it has a pin in the centre for sensing the power, a Dell ? It could be an HP but either way you will have to spoof the sensing. HP use resistors and Dell a chip.

I think it's easier to just tell us the brand/model of the laptop and can work backwards from there. Hopefully it does not use a custom chip to supply.

Dell
Sony
HP
Lenovo

It is a dell N5010, it calls for a 65W brick
i did try it by bypassing the jack completely and it did work, i disabled the power adapter warning in the BIOS

will it just throttle the laptop without the sense?

Re: What size barrel jack is this?

as far as I know, it will simply charge slow or not charge at all if it can't ascertain the charger.

Re: What size barrel jack is this?

as i have no battery, that is not really an immediate concern

Well, the implication is that it could simply not power the CPU either, so throttling is indeed possibility... or simply shutdown...

who knows what the firmware says...

Using a non Dell charger on a Dell will mean it's throttled and won't charge the battery at all.
It's fairly easy to make something to spoof the charger though. https://hackaday.com/2014/03/03/hack...dentification/
