PLEASE HELP! PROTEUS 2/3 Laptop

Hello!

I recently bought a spares and repairs Proteus 2 Laptop.
Upon inspection, it seems a 180w Charger was used when the Laptop needed a 150w adapter instead.
The Laptop does not turn on and battery does not charge and there seems to be damage around the power socket port.

I do not have warranty as the person i bought it from is not the original owner and claims he does not know who is, therefore i cannot use customer services for help :(

At first i tried to find a new motherboard
Quanta NL8B

I have been looking for nearly 2 weeks now and haven't been able to find anything, despite the same model being used in Dell, Clevo and LLEGEAR Z5 Laptops.
So i turned my attention to the Power socket. If i can de-solder and re-solder a new socket port to the motherboard as this seems to be where the damage is, and use the correct charger (150w) hopefully this will give charge to the battery and the problem will be solved.

I have no idea what Power socket port these laptops take..
Can someone please help?
Thank you
Shawn

Even if the laptop isn't in Warranty, I'm sure PCS will help you out if you give them a call. That's where I'd start.

If there's damage around the power soldering port, it's unlikely to be just the port that's affecting, it will be the circuitry around the PSU that will have been overloaded. i doubt just resoldering the port socket would help much anyway.

Also, I can't see why a higher rated charger would cause any problem unless it operated at the wrong voltage ?

I have rang and emailed pcspecialist numerous times, thr first question they ask is my account number/ID which i dont have. After explaining the laptop is bought elsewhere and ehat the problem is, they say they cannot help and give info on parts or part numbers as i am not the owner.
The port socket itself is burnt out and is visably damaged. So i am looking to get a new power jack socket, removing the old one, and adding the new. Along with the correct 150w charger, i am hoping this will work. But how do i even know which socket port i need?

The charger port is burnt out, the charger used is 180w when it should be 150w. I am guessing the burnt out port (which has melted the case slightly too) is thr problem, and not a full motherboard change. As the nl8b is impossible to find.

If you ask pcs to sell you a new motherboard I'm sure they would. The power jack won't be the issue as that just passes the current into the motherboard. The issue will be the psu circuitry at the very least, more likely though it will have fried the motherboard.

I will try ringing them again and getting a price of a new motherboard.
Update:
"Thank you for your email, I can confirm that we are only able to provide spare parts and warranty advice to the original owner of the system."
The PSU charger that was originally used was the chicony 2 180w,
My Proteus is a gtx 970m but i believe that gpu can be used for both the proteus 2 and 3? The 2 would be 150w and the 3 180w and i unsure which model mine is.
Is there any other way to tell what wattage power supply i will need?

The BSOD Doctor
The power supply power rating (wattage) is not the cause of the charger socket burning out. The power rating simply defines the maximum current (given a fixed output voltage) that the power supply can deliver, it will only provide the charging current demanded by the laptop's charging circuit however.

If you should have been using a 150W charger and you used a 180W charger (assuming the output voltage, polarity and connector size were all correct) then nothing dangerous would happen. You'd simply have more power available in the power supply than the laptop needed.

If you should have been using a 180W charger and you used a 150W charger (assuming the output voltage, polarity and connector size were all correct) then when the laptop battery was flat you'd find that it would take an age to charge and it might not even charge fully. This is because the 150W charger couldn't supply the current the laptop required.

The most common reason for a charging port to fail when using an after-market power supply is because the connector wasn't quite the right size. If it's not a good fit and it can move, then when the laptop battery is flat the high current being demanded from the charger can arc as the plug moves in the socket and it's the very high temperatures in this constant arcing that destroys the connector.

This is the answer i was looking for.
On closer inspection of the old charger (180w) i noticed that it has been modified and the cable is alot different to what it should be.
I have bought an official 150w charger and a new socket port (could not find what type but nought about 6 that look similar)
So hopefully when the new port is soldered on, this will fix it and hopefully the motherboard hasnt been burnt out.
