1. First I investigated how sliding switches worked by reading http://www.globalspec.com/LearnMore/Electrical_Electronic_Components/Switches/Slide_Switches
2. Then I looked at the pictures here http://netbookitalia.it/samsung-n150-n150-corby-giallo-guida-disassemblaggio.html to see how to take my netbook apart. I know its in Italian and for the N150 but it gave me a guide.
3. Then I went to my local ectronic store, in this case Maplins and purchased the following
– Soldering Iron Kit (£20) including soldering iron, solder, stand and solder sucker.
– 1 Submicro 1P2T (£1.49)
– 3 different colours of 2mm multicore wire (£2.04) in each. You could use one single colour but i used three to help prevent confusion. If I did it again I would use 2mm single core wire instead.4. I followed the guide in the Italian website and took my Netbook apart, carefully storing the screws and noting what ribbons, cables etc went where. PLEASE NOTE THE SCREWS ARE POZIDRIV SCREWS AND YOU SHOULD NOT USE A STARHEAD SCREWDRIVER AS YOU MAY DESTROY THE SCREW HEAD AND LEAVE THE SCREW STUCK IN FOR EVER. I BELIEVE YOU NEED A SIZE 0 OR 1 POZIDRIV SCREWDRIVER. Note there is a ribbon in the centre bottom of the motherboard, to release it from its holder just pull the brown piece of the holder towards you a mm or so it should then release the ribbon. To fix the ribbon back into the place, just slip it back into its holder and push the brown piece back in again. You do not need to use great force and the brown piece as in the Italian diagram is part of the ribbon holder and does not need to be removed. The rest of the connections fittings etc are just ordinary cables and can only go in one place.
5. I then de-solder the orginal switch from the motherboard. The switch is surface mounted and does not go thru’ the board so you just de-solder around the switch. This leaves you with four solder points on the Motherboard, the two in the middle are actually connected and are the common.
6. I then soldered three short pieces of wire on to the the motherboard where the orginal switch was placed. I had stripped the wire by using a old pair of plyers.
7. I then soldered the three pieces to my 1P2T switch. The central wire going to the centre leg of the submicro switch the other two wires going to either end of the new switch.
(Note if I did it again I would have soldered the wire to the switch first rather than the motherboard)
8. I then put my netbook back together, having of course checked and rechecked everything was connected correctly and firmly.
9. I then plugged in the power supply. No big bang!!!!!
10. if you just flick the switch on your Sammy will just try to start and the cut off. What I discovered is that you have to flick the switch on then after a second off. This replicates the springing back motion of the original switch on the motherboard.
11. You then decide what you want to do with your external switch. I have it hanging out of my case because i just want to use it at home. If you care about beauty and design you may decide to fix it to the case somehow.
My N130 is now working. if you can borrow the soldering/de-soldering equipment. You could actuall do this for less that £5 if you used only one colour of wire. You actually only need about 20 cm or 9 Inchs or wire, so if you could get an off cut somewhere, you may need only pay for the switch.
Anyway it took me about 30-45 mins to complete the whole project. PLEASE NOTE THAT THE SCREW ARE POZIDRIV SCREWS NOT STARHEADS. IF YOU USE A STARHEAD SCREWDRIVER YOU MIGHT TAKE THEM OUT BUT YOU MIGHT JUST RUIN THE SCREW HEAD AND HAVE THE SCREW STUCK IN FOR EVER.
btw I studied electronics at college 22 years ago and worked as a computer technical for a number of years, therefore I had some experience of soldering/de-soldering etc. Please note I am only telling my story if you follow it, you do so at your own risk. I do not want your widow suing me in court.
Please note that I have learn’t over the years to investigate and plan. Have a good clear work surface, have containers handy for storing screws and other things that have been removed. Be observant and note what you take out and where it needs to return to.
good luck and be careful out there
I finally decide after months to de-solder the switch from the motherboard, soldered on three wires, soldered the three wires to an external switch and got my netbook working fine. I tried to explain in detail how I did it if anyone is interested say so
Ok my N130 was sitting there for months a useless lump of plastic and wires. I had investigated getting the replace switch “SWITCH-SLIDE;4V DC,0.3A,1P2T” part from Samsung but they quoted me £49.99 plus VAT. I hadn’t got this cash so I left it for a while. However it came to a point that I needed the Netbook again.
I had once seen an ad on e-bay for a company in England that would remove the switch from the motherboard and replace it with an external switch on the case but again they were asking for £50 plus postage charges.
So therefore I decided to do the job myself. I went to Maplins bought a very very basic soldering iron kit for £20, three different coloured wires for £2.04 for a metre total £6,12, the wire was 2mm multicore, I suggest 2mm single core would have been better and finally a Submicro 1P2T sliding switch for £1.49.
I had investigated sliding switches at http://www.globalspec.com/LearnMore/Electrical_Electronic_Components/Switches/Slide_Switches
So I could understand what I wanted.
I then took the Netbook apart, I had not done this before so I use the following link as a guide, it is in Italian and for the N150. I used the photo’s to indicate what order I should do things in.

I removed the HDD, RAM and the FAN. then I disconnected all the various cables and wires. I haven’t a clue what each one did but just noticed were they came from so I knew where to put them back. I then only had to remove one single screw on the left of the motherboard as the other screws holding the motherboard to the case were also holding the HDD and Fan so they had already been removed.The original switch is PCB mounted so that it’s pins do not go through the motherboard they just lay on top. So I de-soldered the pins from the motherboard and removed the switch, it came away very easy with a bit of assistance from a small screw driver.
I then soldered three pieces of wire to the motherboard, you may wish to solder the wire to the new switch first as doing this later was the hardest part. The centre wire goes from where the central pin of original switch was on the motherboard to the central pin of the new switch, then the other two I just connect to the other two legs of the new switch. I left the new switch hanging free, not fixing it away as yet.
Job done I rebuilt the motherboard, connecting wires cables and components etc. I was careful to check that all things where connected.
I crossed my fingers and plugged in the power. No big bang so that was lucky. I then switched the new switch, the Sammy attempted to start then it cut off. After a little head scratching figured out that you have to switch the switch on then after a second off again. So far so good my N130 seems to be working OK and I have shutdown and started it a number of times. It is now currently updating my anti-virus.
I have not yet decide what to do with the switch, whether to fix it to the case or leave it hang out the front. You can decide what to do for yourself. I don’t care about the handing switch as I am generally a slob anyway.So my Sammy N130 is now working and it took me about 30mins in total to repair. Please note I was willing to risk it and I have a little electronics experience from years ago, so if you want to do it then it is up to you.
