Thank you so much!

Благодаря :) този който отворих беше малко по=различен от този който показваш на клипа , но разликите бяха минимални :)

[@LaptopDisassembly]

Радвам се, че съм помогнал.

Hello and thanks for the tutorial, I still have a question: to replace the speaker is it necessary to remove all the screws or is it enough to remove only the keyboard and disconnect the cables that connect to the motherboard?

[@LaptopDisassembly]

To replace the speaker, you need to lift the hole upper plastic. It is hold my all the screws on the bottom cover, so yes you need to remove all on the back, and 2-3 under the keyboard.

@@LaptopDisassembly Many thanks!

God bless you Acer Travelmate 5742G laptop. When I turn it on, sometimes a black screen appears after turning it on, and sometimes a blue screen says there is an error in the screen program, and sometimes it works for a quarter of an hour and turns off again. What do you think is the reason? You have subscribed.

[@LaptopDisassembly]

You can run a MemTest to test the memory. Also remove the memory, clean the contacts and plug it back again. And if you have 2 memory sticks, that to work only one for test. I think there is a problem with the memory.

Hey Yanko, thank you very much for making an Acer Aspire 5742G disassembly video. I already cleaned the fan and heatsink module, but it is still overheating when my laptop turns on and shuts off immediately. Should I replace the heatsink and fan? Thanks!

[@LaptopDisassembly]

Did you replace the thermal paste. Also is the fan spin freely. Any info about the laptop will be helpful. Any CPU update or...

[@JBALwastaken]

@@LaptopDisassembly I did replace the thermal paste and the fan spins fine. I also already cleaned the heatsink but still getting hot.

[@LaptopDisassembly]

Well can be a faulty cooler, or a faulty CPU.

[@JBALwastaken]

@@LaptopDisassembly Oh wait, I cleaned properly the heatsink and it works great. Thanks Yanko for the reply and the video.

[@th6368]

Thanks for the video - I'm stuck at around the 1 minute mark though. An ssd has been installed in this one and I can't get it out. Doesn't seem to slide or lift but I've removed the screws - any help much appreciated..

[@LaptopDisassembly]

Are you talking about the small board between the ram memory and the regular hard drive. If yes, that is the wifi module. Probably it have some type under it. When you remove the screws just lift it gently on both sides. It should come out.

[@ThinkForward0]

My fan seems not to work , so is it pointless for me to pick it apart and clean it? Or should I just go to a store and replace the fan?

[@LaptopDisassembly]

All depend on the situation. There can be a little piece of dust blocking it to spin, it may need a littlw machine oil to it can spin freely... You will find out when you disassemble it.

[@desouza6596]

İnstall SSD (i use CD slot) and change 2x2 gb to 2x4 gb ram,. clean fan and refresh thermal.

[@LaptopDisassembly]

SSD will perform better if you plug it on the place of the regular disk, and put the disk in caddy on the cd place.

I saw plastic sticker above graphic processor can i remove it. ? I want apply new thermal paste

[@LaptopDisassembly]

If is plastic is not supposed to have thermal paste i think.

[@GozzoGe]

Please can you help me to locate the speakers, of my 5742 G, which need to be replaced, one of the two is heard close to the cooling fan, but unfortunately even looking at your tutorial I cannot see them. Thank you Franco from Italy

[@LaptopDisassembly]

I disconnect the speaker around 5:10min. You cannot see it on the video, because the speaker is screwed on the top plastic, next to the power button.

[@GozzoGe]

@@LaptopDisassembly Thanks a lot

[@olaitanlabs5948]

I have damaged my screen hinges with forceful disassemble, not only that but my fans aren't working anymore 😢😢😢

[@LaptopDisassembly]

This model is notorious about hinge problem. They start to loose from the bottom cover and brake the plastic. If that is the problem you didn't brake them. They were already broken.

[@olaitanlabs5948]

@@LaptopDisassembly I think that is the case

[@LaptopDisassembly]

@@olaitanlabs5948 Use some hot glue or else ant try to glue it and put the screws between the upper and lower plastic. It should work fine. But first check is the power jack ok, coz sometimes he get broken also.

[@olaitanlabs5948]

Okay Thank you, I'd try that

[@GozzoGe]

hi Yanko, thanks to your advice I was able to replace the Speaker of my 5742G, I saw in your video that the models are very similar, so I contact you, unfortunately the lucky ones who want to change the CMOS battery just remove the cover that protects the hard Disc and RAM and would immediately find it there near the network card, while the unlucky ones like me do not even know which battery to buy as it is connected (maybe it is soldered to the motherboard? Or is it one of those that have cables and connector?) But especially where is this damn battery located? I wasn't even able to identify it from your video, can you help me please? I assume that in my case I will have to disassemble everything to get to replace it, I state I'm starting to use this PC assiduously now and since this is more than 10 years old, sooner or later the problem will arise, I replaced the Hard Disc with an SSD from 1TB while the RAM despite those purchased were compatible I returned them to Crucial because the PC was unable to load the Operating System, I wanted to go from 4Gb to 8Gb. however there is no big difference the SSD disk makes the laptop extremely faster, please help me to identify where the CMos battery is located and what type it is so that I can get the right one. Thanks in advance Greetings from Italy Franco

[@LaptopDisassembly]

The battery is on the left bottom side when you lift the cover. It si like this one. shopee.ph/amp/ACER-Aspire-5740-5741-5741G-5742-5742G-RTC-CMOS-Battery-i.158450637.6062647863 You can use a regular one, but you have to solder it to the board. Just buy one like the original.

[@GozzoGe]

@@LaptopDisassembly many thanks, but can you see on your video? can you give me the time of the frame?

hi idont now why when i start a game the Acer Aspire 5742 shut down

[@canozal35]

my 5742z is not working. Even without battery I pluged tothe adapter and there is still no light and nothing happening. Tried to unplugged battery and pushed the power button 30 seconds and then pluged it to the adapter whike pressing Fn +esc but still nothing happaned. What can it be??

[@LaptopDisassembly]

You probably have a short on the main 19v power rail. If you have a multimeter try to messure after the first and the second mosfet what is the resistance to ground.

[@ozanyaman-oznymn7242]

İ had this problem too i solved this by ramowing my ram and getting new one

[@thomasdunaway2573]

Will this work on a 5740

[@LaptopDisassembly]

It should work, they are pritty much rhe same about disassembly.

[@narxerinobyalex]

I got this error when i turn it on: error sending end of post message to me

@@LaptopDisassembly Yes, I looked for it on the Internet, apparently there is no solution but I do not understand why it happens, I have not broken anything ...

[@LaptopDisassembly]

If you can get in windows, try to upgrade it via Windows. If not, test memory with memtest.

[@euroboyvevo2327]

My acer aspire 5742 fan not working

[@LaptopDisassembly]

Disassemble it and check is it moving with hand. If yes probably there is something blocking the movement. If it moves easy, probably you have to replace it.

[@johnnybuoy9551]

the problem is not disassembly.. The real problem is the reassembly

[@bryndentully9235]

Exactly, i cleaned my laptop but now i just can't rebuild it. I shouldn't have got into this thing, i'm very bad with computers :(
