    Hi everyone, it's been a while since the last time I came here.

    I'm have a problem today, my laptop fell while charging and was damaged. The DC port inside the laptop is still soldered but is not aligned correctly anymore and the stuff in it seems weirdly twisted...
    The laptop can charge "normaly" but there are some instances where there is a loose connection and the laptop switches between "charging" and "on battery" rapidly.
    It means that performance in games is horrible. FPS are even better on battery... (10-15 FPS, when plugged in Far Cry 5, normal quality, 25-30 on battery). I don't know why the CPU is stuck at 0,78 GHz in games but works fine the rest of the time.

    Do you think the probem could be solved with a new DC port (where the hell do you even find that) or is the motherboard damaged and needs to be replaced ? (hella expensive). I've had a bad experience with the outsourced Gigabyte service in my country so...

    Thank you to anyone who can give me an answer for this old laptop !

    It's a gaming laptop so battery life is average because of the powerful CPU and it decreased since I bought it. Maybe 3h surfing and 4-5h working with good power management.

    That is unfortunate. It does depend on the model/motherboard if it is a simple jack replacement or full motherboard replacement. I unfortunately do not know for this specific model. I would recommend contacting Gigabyte directly as they can likely get you on the right path. Although do note, they for the most part do not send replacement items to customer, traditionally you would always need to send the machine in for repairs, which can be costly.

    DC jack can definitely be replaced. But make a good photo of the damage first; if it's just a loose pin then there's no problem, but if the fall also stripped some tracings from the motherboard then there's not much hope.

    Replacement jacks can be found on ebay, aliexpress, mouser or digikey. Problem is that there's tons of different ones, so hopefully there's some markings on the jack. Schematics would also tell you the part number. Last resort is simply checking for a visual match.

    Swapping it is tricky. Most likely it has four or more pins (through-hole), so a soldering iron won't do. I suppose you could diy a copper gizmo that heats all pins at once, but a good hot air station is a much better option. If you don't have one at your disposal then take the board and new jack to an electronics shop (expect a $25-30 fee).

    Yes, if you are able and confident by all means you could resolve it with some solder potentially.

    Thank you all for your answers. I guess I don't have no choice, I'll have to ask Gigabyte for potential cost. I have a new standard laptop now so I don't know if I'm willing to spend that much on my old laptop.

    Hello everyone!

    This thread is old but guess what... I managed to fix it!
    I found a replacement part on eBay and told myself why not give it a try. The seller was fast as I was delivered in 10 days from China. I received the replacement part yesterday and went to buy the necessary tools today.

    So I'm used to opening this laptop, I've done that a dozen times but I had never gone deep and my attempts at finding a disassembly guide for the motherboard were unsuccessful so I decided to do it by myself, slowly and carefully.
    It wasn't that hard actually, I just had a bit of trouble removing the battery and the keyboard. Both were held in place by very strong pieces of tape. It was a pain to remove them. But the biggest hassle was to actually desolder the old DC port. I had already used a soldering iron in middle school but it was my first time desoldering a component so it took me an hour. Soldering the new component was very fast. My heart was racing when I turned the laptop on but I immediately saw that everything was normal! Usually the screen would flicker and I would have troubles to enter my password and then everything would be slow.

    I'm very happy because this has been pissing me off for a whole year.
