MSI MS-10571 no power through DC

[dethica]

Hi,

I got a laptop which works fine on battery, but will not charge or work through the DC jack.

There is a slightly loose (physically damaged) component right behind the DC jack, but I could not find any info on it. The marking on it is K702. I soldered it a bit, to make sure it makes contact, but it didn't help.

The DC jack seems to work fine - nearby components are getting voltage, but the MoBo won't turn on without the battery.

Any help with this motherboard will be appreciated.

You need to remove the dc socket and clean the holes and fit new dc socket start with first

If lack of ground it won't power up. You have 2 connections on the dc jack, use bench power supply to power the board. Inject behind it and the other one to the ground just to find out.

I found a donor board with the same K702 component and same DC jack, replaced them both. Still not powering up.

Hello
You must plug the powersupply and than check the voltage
at the green Resistor R0202. it must be 19v.
