Thread Starter 
My AC adaptor has broken, looking at a replacement they cost $90!! The end of the adaptor just came off, it didnt look like a good solder to me. I simply cant afford that so I have to try and fix it can anyone help me out??

The adaptor part that slots into the laptop has falled apart, ie the metal bit has come off the rubber part, and the connecting wires are buried inside. I have cut open the rubber part and the 2 wires are exposed but I dont know where to connect the 2 exposed wires to the metal connector. Also what wire should I use to connect the two?

Alternatively is there anwhere that I can purchase the 'head' that goes into the laptop?

Thanks a million guys

Check the Clevo web site for the manual for your machine. I don't know if it will help but it might.

Otherwise, you might ask PCTorque or the Sager Techs if they can help.

Alternately, if you can open the case of the power supply brick, check which wires come from where and see if you can determine which is positive and which is negative or ground. That might help in figure out what goes where on the other end. Usually the outside of the plug is negative or ground but my adaptor has four small prongs inside which I haven't a clue why or what each does.

Perhaps someone else can help out there.

i have not seen the 'power supply brick' as you call it, but i would recommend not opening it, as it is a transformer and may have capacitors in it holding a charge that can shock you...if it is a split cord, there should be one side with either a white line, writing, or several 'ribs' running the whole length of the cord...the ribbed side, if i remember correctly, should be the positive, but you might want to email sager or adam about what you can do with it

I just looked on the bottom of my adapter ther is a diagram of what pin is what.I don't know if the adapters are the same for the 888x and the 56xx or not. Most of the adapters I have seen have something similar. Good luck.

That sounds a bit like the problem I had. Does the "head" look like this? The end of the "head" burned out and two prongs fused together.



If so, then tell Sager about it, give them your notebook's serial number and they'll give you an RMA#. Then you just send it back to them and they'll replace it.

It looks [/b]exactly[b] like that. But, I have cut off the part that it was attached to to try and fix it myself - dunno if they will RMA it like that??

I guess you should email them about it.

websupport@sagernotebook.com

Just explain that the end of it fused together and how you tried to fix it on your own.

They asked me if there was any man-made damage on mine...that might be a problem. I don't know how else to help out.

Yes def. take extreme caution. I remember taking a TV apart in an attempt to fix it once, noticed it had a blown fuse, went to pull the fuse out and ZAPP. I later learned that CRT monitors (and TV's) have HUGE capicators that can hold very strong charges. If you ever HAVE to take a CRT or anything like that which holds a large charge arpart take exttreme caution. 1st leave it unplugged for a while (one day should udually be enough). 2nd Don't ground your self like you would when servicing a computer, grounding just provides an easier path for the electricity...through you. And finally if your servicing a CRT/TV after steps 1 and 2 be sure to properlly discharge it using a flat head screw driver (don't try it if you don't know how).

My teacher even told me a story of a guy who left a monitor unplugged for over a day, opened it up, touched the wrong thing and got shocked to death. So be warned that those capicators that can hold an access of 30,000 Volts, more then enough to kill you.

Sorry about the long rant but when i went to fix that TV i could have pretty easily killed myself since at the time i had no idea what i was doing.

Yes good recommendation is to not mess inside a CRT monitor.. They have high voktage anodes in them that connect to the CRT that holds 25KV+ and will hold that charge if unplugged and can hold it for up to 2 years unplugged(From A+ book) it shows how to discharge it but also recommends to not open a crt monitor at all..
