Laptop repair tools 12. Disassembly tips for beginners New replacement batteries available here. Just follow instructions in steps 6-11. New replacement keyboards available here. Is this correct and what can be done to repair the motherboard chipset or bypass with a video card? I believe that the power jack is bad do you have instruction on how to replace. Thanks Frank In order to access and disconnect the power jack harness you’ll have to remove the motherboard. Take a look at this guide for Acer Aspire 5741 laptop. I think this will be similar to Acer Aspire 5733. At the end of the guide I explain how to remove the motherboard. There is a chance it will not be 100 the same for your laptop but you’ll get the idea. Good luck. They confirmed there was no screws holding the keyboard in place. I had to disassemble it to clean the cooling fan. After reassembling it the microphone doesn’t work. Everything else is working fine except for the microphone. Although,when I open the recording device it has a green tick beside it showing that the microphone is recognized. What do you think the problem might be? Thanks. I believe that the problem is a faulty DC Adapter. My question is in order to change the DC Adapter will I have to remove the motherboard or it’s less complicated. I would greatly appreciate any help. Maybe you have a guide on that. Kind regards Eduard. I’ve got another question with my Acer Aspire 5742G. The battery indicator just continously blink. Could it be my faulty settings.Please advice. Thanks. Where does this get placed and where does it connect. I was having issues getting the bluetooth to work, only to find out my computer never came with the module only the software, which obviously was pointless. Help please. I know some about desktops. I have Compaq CQ42 laptop and developed a problem. It works well with a compatible battery replaced recently.

But when using audio or internet or any other application within few minutes, every task start hanging (system becomes very slow), audio distorted, MB gets over heated, fan sound is audible. But surprisingly if I connects power cord to charge, at this moment almost every application resumes to normal speed, except audio distortion. Or motherboard has developed any problem, Any hint please. Great tutorial. I have a question, the internal speaker failed, I opened it up, unplug and plug back in speaker cable but still the same, is it likely to have speaker failure or it is Mainboard fault. Thanks a lot! This is so usefull and helpfull. One question before I start disassemble the Notebook: Do you remember if the Notebook have a MXM B Interface wich make it possible to change the GPU. Kind regards from Germany My computer has been overheating lately (to the point of shutting down) and have had some success in this situation with other laptops just by vacuuming out all the dust, etc. Do you know of any known issues like this with this model, or can you recommend any addition action to take. Thanks so much! If your computer is still Overheating after cleaning out the dust with a Vacuum or Compressed Air you may need to Remove the Fan from the Processor. After the fan is removed from the Processor you’ll need to apply Rubbing Alcohol to the Lint Free Cleaning Cloth. Next you will need to Clean off the Old Thermal Paste from the Processor and Heatsink that touches the Processor (The Heatsink should be on the under side of the Fan). Once the old Thermal Paste is removed wait for the Alcohol to dry. Once Dry apply a Pea sized drop of Thermal Paste to the Processor Core (right in the center). Follow steps for Disassemble in reverse to put your computer back together.In this case just forget about it and use two port on the right side. If you are talking about USB ports on the right side, they are located on a USB board (it’s a separate module, not a part of the motherboard).

In this case you’ll have to replace the USB board. Have I missed it, or is there instructions elsewhere to accomplish this? Thanks. After that you will have to take apart the display panel and remove the screen. Take a look at this guide for the screen removal instructions. When the top cover and screen removed, you should be able to replace the display cable. I had opened before (6 months ago), and i clean everything. Does this will keep happening? Also, I would test RAM. A faulty RAM module also can cause shutdowns. The heat sink located under the motherboard. If you want to replace thermal grease on the CPU, you’ll have to remove the motherboard. Just the keyboard and top cover? Thanks! There is no shortcut. Much appreciated. That’s okay though, I usually have an external keyboard connected anyway. Now I’m too afraid to disconnect the other 3 cables as depicted in step 13 because I don’t really understand how they work. I’m just trying to get to the fan because I’m sure it’s clogged with dust and cat hair. A simple YouTube video is enough to make it overheat and shut off however if I put a fan on my desk point it at the laptop it won’t overheat. Needless to say it takes up too much space on my desk and is too loud and is just not a good solution. Thanks for the tut it’s getting a good clean tomorrow. I followed all the steps to clean the fan. But on assembling again my laptop does not start anymore. Can you plz help out with this problem. Both the lights near the power button does not glow. My laptop now has a new keyboard fitted and much fluff has been removed from the cooling fan. Thank you. It is getting very hot. Am I supposed to clean out the fan from dust. How do I go about this. THANKS! Lois I have on alphabet character. I closed the lid to return to work from the bottom. I may attempt a repair with epoxy if I ever have to go back into it.

I had to remove the fan, to remove the power port from the case, and remove the motherboard as the power cable plugs into the underside of the motherboard. After removing the power cable, I checked it for continuity with my multi-meter, all wires “good”, plugged into power supply, all contacts had correct voltage. I took pictures, but don’t know how to upload. I have tried Ali Express twice and both times they sent me the wrong part. The add was for a jack for a 5742 with a picture, but what they send is a piece of plastic with no jack at all. I have got 50 refunds. Anyway the problem is finding a place to buy the jack for the motherboard. Help needed. Meaning that, basically put, you’ll have to go through all of the dis-assembly points shown. The 5742s are prone to getting very hot. And replacing the heatsink will result in having to get access to the motherboard. Why are modern laptops so difficult to repair. No motherboard access required. I fix my desktop PCs but never a laptop, but the step by step walk through made it straight forward.Cate o data activez inainte de a intra w7, alta data nu sau uneori intra automat in wireless. Cand functia nu este activa nu gasesc adaptorul in Device manager, iar in activitate o gasesc. Care este problema si cum o pot remedia. Once I activate before entering w7, another time it doesn’t or sometimes it automatically goes into wireless. When the function is not active I do not find the adapter in Device manager, and in activity I find it. What is the problem and how can I remedy it. Thank you. nonu.
