AC adapter problems with p775dm3

Just wanted to ask if its safe to use the laptop since i got one pin kind of burnt...looks like almost it almost welded.

Second pic is a bit blurred but you can see the different colour of the bottom right pin hole.

Really dont have a clue what might be the cause, power surge, that pin drawing too much pfff out of ideas. Unplugged it yesterday evening and this morning i tried to plug the cable back in into clevo and it didnt want to "click" (not click as an actual click but that feeling when you know it is set in place). I always make sure its firmly set there before i turn the laptop on, so i dont have a loose power supply cable. After checking the cable and the clevo "power socket", i did manage to put it back in with a bit of force. Nothing burnt out yet, its working so far normally but i am worried a bit. Sent a ticket to my reseller and waiting for them to reply but just in case it takes till monday i wanted to check with you all also. Is this a problem?

So far i never had a problem like this except at work where the extension cord for a big ars machine welded itself together with the machine socket almost the same like this cause it was drawing too much power hence my worrying about this.

thanks in advance, cheers all

 

I would get a new cable/ adapter as it is a lot of money to gamble with.

Plug should be able to handle the power without any issues

 

ye was afraid of that cause if i order it on monday itll be here by friday, thats a week of gambling and i really need the laptop to work until the adapter arrives....mhmmm ill just have to gamble and hope it doesnt burn itself

I wouldn't risk using that. I've only seen discoloration like that on CPU +12v 4 pin plugs being used where the CPU was drawing too much current, and needed an 8 pin plug, but only a 4 pin was used. So twice the amount of current was being sent through the 12v wires as they were designed to use, leads to burnout. I'm not sure how that would happen in a laptop however.

Were you overclocking anything? CPU? Videocards?

 

Nothing by myself, clevo came oced to 4.5 ghz. Its a 7700k, 1080 gtx, 16 gbs of ram. Normal cloak is 4.2 ghz i think, for that cpu. It was bought off of Obsidian a couple of months back. So it was tested before shipped and everything was normal until yesterday...dunno how it got like that today. Crap eh wont use it until guys at Obsidian contact me back.

im using the laptop on oced profile for 2 months now for sure, everything worked out as it should. Even played for 12 hours on it straight almost every sunday, dont know why it burnt out now. What if i keep it on normal profile or even underclocked? Would it still be a high risk?

When did you first notice it was burnt? Because things like this don't usually happen suddenly. They happen with time. Was it just after when you had trouble inserting it and it didn't click? How do you know for sure it wasn't partially burnt until then? You wouldn't have known to look for a burn if you didn't suspect a problem right?

And I would undervolt it and underclock the CPU (maybe down to 3.5 ghz) until you get a new PSU.

 

It today, i left it run yesterday around 8 pm, D3 was running on it at a time, forgot to exit the game. Got home around midnight and noticed that laptop was shut down. Tried to turned it on again and it didnt work and i noticed that the cable was not plugged in. It was when i left and that seemed strange but it explained why the laptop is dead, battery emptied. Tried to plug it in and it fall off. So i left it till morning cause it was well dark. Woke up and plugged it in with a bit of a force, not much. Turned it on and everything worked, battery was at 0 naturally. Cheked temps with hw, throttle stop, aida, etc have like 5 different apps for that, everything was fine but it bugged me why was it out and didnt want to go in as easy as it did before. Unplugged it and saw what i saw. Took pics, sent obsidian the pics but since its saturday dont think they will see it until monday. Then decided to post here. Laptop was running half of the morning. Temps were fine. Still i turned it off and unplugged around noon. After i got the first reply from you guys havent turned it on again.

It's very possible that the cable was partially inserted or had somehow come partially lose due to laptop movement or something touching the cable, and then slowly worked its way out, combined with partial current (like 2 of the 4 pins connecting) causing overcurrent. Does that sound like it?

I remember another post about someone having a cable (same PSU) that wouldn't stay in his laptop and he also had a burnt pin. He said the cable never stood in even when new and would always scratch the back of his laptop (it looked like an angry cat had gone all around the back by the cable plug). Might explain some things....

 

hmm it might since the cable was out

dont see how tho, it has plenty of room, laptop is always on the same spot on the laptop cooler stand, it does have a curve 5 cm below that thick end just below the "pin holes". And now that you mention it, it never was a tight fitter, could always plug it in with no effort what so ever but until yesterday it never fell off while standing still, it did fell out a couple of weeks ago when i had to take it out, but i shut it down before so wasnt paying much atention to that. Since adapter is heavy thought it just fell cause i raised an adapter alongside the laptop while trying to unplug it so the pure weight of adapter unplugged the cable. It fell on my foot tho so no harm except my toes

Ah anyways if its that and i continue to use it and it happens that it is current does the warranty still applys?

Im bugging cause it will take 2 weeks to get it back to obsidian and back to me and of course im going on a frikking trip tomorrow and wont be home for 3 weeks. argh

p.s. if it did drew too much current wouldnt all pins be burnt? Or just that one cause its "weaker". Eh anywho, advice still stands of not touching it and buying a new adapter before using it?

It's very easy for the adapters to be positioned to pull on it slightly.

 

mhm but if that happened than all i have to watch for is the adapter positioning, everything else should be working fine or am i wrong and i should not touch it until new adapter arrives? (ugh i cant stand that option but eh if it must be done )

If it's REALLY loose then something is up and I would avoid using it if possible.

 

damn agh case closed than ill rma it in monday....now to figure out a way how to take my desktop with me....thanks to all of you and sorry for bugging, i was hoping that it just might be ok but eh...cheers

You weren't bugging anyone.

Is your CPU socketed or soldered? Because if it's socketed, one big advantage is you can buy a pre-binned CPU separately and then just install that, and if something happened to the mainboard which caused an RMA, if the CPU were intact, you would keep your binned overclock.

 

Laptop is "still on a warranty", nothing broke, its working and last time i turned it on was yesterday half way through our chat just on battery to see if anythings amiss (everything worked, no funny noises, nothing smelled, everything was like it should be) and then i shut it down and packed it in a box that it came with. Im still waiting on Obsidian to contact me, but since its weekend i dont think thatll happen till monday. Think its socketed since the whole rig except the case, mbo and gpu is "installed" (delided, repasted etc) by them, but since the warranty still is in place id rather not touch anything and if they say send all, ill send all.

Whats bugging me the most is the semi vacation semi work trip i needed the laptop on with me and it starts tomorrow. Was really counting on it, never thought something like that could happen so i got no backup now. Eh hope someone there has a laptop willing to borrow. I wont be able to rma it for the next 3 weeks. Eh what can you do...lucky we are living in a time of a big ass usb sticks, cant imagine the floppys id have to take with my PPP

 

The only times i have seen something like that happening was with a "partial" connected plug, like not totally inserted, like when someone trips on it.
Poor grounding can also cause problems, so make sure the wall plug is connected to a proper grounded circuit.
If the damage is done on both the laptop and AC adapter i would rather just replace both ends just to play it safe.

 

Talked to Obsidian. To recap, after a long chat with them about this i got 3 options. 1. they both strongly agree that i should send the laptop back to them so they can fix it (which ill do in about 3 weeks if i dont mess it up first), 2. a bit safer would be to order a new adapter but again their advice is to get it back asap so they can see and fix the cable and the pin, 3. i use it but check the heat on the cable and if its melting i unplug it ( but if i mess it up theyll fix what they can but if they have to send it to clevo its on me). So bottom line i think ill risk it with trying to work on it, wont stress it at all and hope it lives for 3 weeks and when i get home ill just send everything to them.

Thanks all once again for the help and big thanks to John and Ricardo (whom im still bugging) for explaining everything from it could be ok to repairs could cost up to xx ammount. Keep your fingers xrossed i dont blow myself up, cheers )))
