This is a quick step by step guide for anybody needing help to install a laptop motherboard, please read the disclaimer before using.
As with any PC hardware, always ensure you take anti static precautions, this is generally taken by wearing an ESD armband.
PLEASE NOTE: this information is not an industry accepted method; these are my own personal fixes that i have determined through many years of handling IT equipment. With the exception of any readers who have bought from my ebay shop Priceattackstorerun by the247enigma, bear in mind these hints may invalidate any warranties you may hold, but if they should I would recommend attaining a refund from your seller and shop elsewhere!
This is a general guide, there are brand variations of laptop meaning that there are different ways of dismantling laptops but this should give you a good idea of how to proceed in most cases.
I personally recommend you to do this in one sitting, so that cable placement and such is fresh in your mind, before you start try to give yourself an hour or so to dismantle and reassemble the laptop, this should give you plenty of time should you find yourself confronted by a particularly difficult problem to resolve it and not feel rushed, these are not PC’s, they need time and patience due to their fragility.
IMPORTANT! Remember your anti static precautions from this point onwards until the final step, and DO NOT place any components on the carpet, if possible use a piece of card or a wooden table to lay any parts you remove.
First off, remove the HDD, battery, whichever removable covers are present and if possible the Rom drive.
Next, if possible, remove the small panel above the keyboard under the screen, screws for this can be underneath and sometimes at the rear of the laptop.
Now turn the laptop upside down and remove all the screws you can see, sometimes a screw will be hidden underneath a label, you will have to try and feel these out when you come to removing the case.
Now turn the laptop the right way up and remove the keyboard, depending on your laptop brand this will either come off now, or there may be some small ‘sliding’ clips either at the bottom or top of the keyboard (but will nonetheless be part of the keyboard), once the keyboard is loose be careful as you remove the cable that you do not damage the wire.
Now the keyboard and upper panel are off you should be able to remove your screen to prevent any scratches or damage during disassembly, there should be one large cable (sometimes 2 smaller ones) that is connected to the monitor plus 2 single strand wires. Try to unplug the cables from the motherboard, now unscrew the hinges, sometimes a screw is at the rear of the laptop or underneath (but you‘ve done that already right?) now this should lift vertically from the laptop, lay it down beside and feed any cables that are connected through the motherboard chassis and out.
Ok, now before you carry on you should have the screen, keyboard and cosmetic cover panels removed, make sure this is so before you continue, otherwise damage may result.
Now begin from one corner and slowly but steadily ease the plastics apart from each other. Do NOT pull the plastics wide apart, only separate them and bear in mind you may have missed a screw or 2, go slow and feel for a pressure point, if you find one you HAVE almost certainly missed a screw, don’t force it just look maybe even try it from another direction if it’s not obvious. On some brands of laptop the outer edge works as a kind of lock, you will need to insert a flat headed screw driver and twist slowly to separate the 2 edges, this is not common so if it seems to come apart reasonably easy please ignore this.
Once the 2 sides are separated, look for cables and unclip as necessary, slowly pull the top from the bottom once you think you have got all the cables, after it’s away place to one side and remove the motherboard.
Once the motherboard is out, compare your new board and move any components from your old board to the new one that may not be included.
Once done return the board to the chassis and connect the cables, leave the screen off and unconnected and do not screw the case together.
Now if possible connect the base to your PC computer monitor using the external graphics port, apply power and test, if it all goes well unplug the power and continue reassembly, check it again and once done get someone to give you a pat on the back, if however you have tested it and find you have problems see below.
Question: ‘My motherboard is completely dead’
Answer: If the motherboard is completely unresponsive there is a variety of possible causes for this, the list below is what I consider the most likely to the least and I suggest following it step by step.
1) Power supply has been switched off at the mains.
2) Inefficiently applied coolant paste or insecure/unbalanced heatsink, take another look at your cooler, make sure it is level and that the CPU fan cable is connected to the CPU fan terminal on the board, if the CPU fan is not connected the board may not power up as it is detecting what would be a critical fault. If the CPU cooler is not level or paste is not correctly applied the PC may have realized this and prevented booting so damage cannot occur.
3) There is a cable unconnected somewhere, double check that all sockets and ribbon wires are the right way up and connected firmly.
4) A hardware conflict or a faulty piece of hardware, unplug everything except your CPU cooler and PSU, this includes memory, if the laptop powers up and gives an error code switch off and place 1 stick of memory in the laptop if it doesn’t switch on again unplug the memory and see if the beep returns, if it does your memory is likely to be at fault.
5) If none of the above work the chances are the motherboard or CPU is faulty and you should contact your seller for advice on how they want to proceed.
Question: ‘My motherboard is powering up but there is no display?
Answer: If the motherboard is doing this there is a variety of possible causes for this, the list below is what I consider the most likely to the least and I suggest following it step by step.
1) The monitor cable is not connected properly, if this doesn’t work try using an external monitor and don’t forget to use the function button on your keyboard to change the output.
2) Inefficiently applied coolant paste or insecure/unbalanced heatsink, take another look at your cooler, make sure it is level and that the CPU fan cable is connected to the CPU fan terminal on the board (not for example the system fan connector, if the CPU cooler is not level or paste is not correctly applied the PC cannot boot.
3) A hardware conflict or a faulty piece of hardware, unplug everything except your CPU cooler and PSU, this includes memory, if the laptop powers up and gives an error code switch off and place 1 stick of memory in the laptop, if it doesn’t switch on again unplug the memory and see if the beep returns, if it does your memory is likely to be at fault.
4) Coolant paste has gone underneath the CPU, causing an issue. Try cleaning it if this has occurred.
5) If for some reason this is a fresh build, check your PSU has a high enough ampage, if it doesn’t it may not be strong enough to power the screen.
6) If none of the above work the chances are the motherboard or CPU is faulty and you should contact your seller for advice on how they want to proceed.
Question: ‘My HDD is not being detected’
Answer: This is a rare fault, check that the drive is setup correctly (see my guide on installing Rom/HDD drives) then if the fault persists its likely to be down to the motherboard, you will need to return it to the seller.
Question: ‘My sound card and/or network port, built into the motherboard, are not detected’
Answer: If you enter bios normally under either ‘Peripheral devices’ or ‘Onboard Devices’ there are settings to enable or disable the sound card and ancillary features, simply set as you require.
Well I think that’s all the troubleshooting, If the problem cannot be resolved above I would send it back to your seller, or if this is not possible have it repaired professionally or you may send it to ourselves for safe and proper disposal.
