It looks like a 3D printed laptop case. Good job Acer !

had this new computer and it would freeze in the bios. i thought it was the motherboard so i got a replacement motherboard. then it would still freeze in the bios. i had two sticks of ram and i just replaced one in the ram slot. it didnt freeze in the bios anymore but i couldnt use two ram slots. so i bought two new sticks of ram and everything worked fine. crazy how these computers do this.

Excellent master class, fast and straight to the problem, thanks for sharing, your South American student, greetings.

Hi @Electronics repair school. the simple laptops have problem recognizing the double row memory modules, always try with the single row ones as they are most likely compatible. Thank you for all the videos, helped me repair quite a few laptops and a tv. Mersi mult Sorin!

You are great!! Excellent tutorial. I think you may have solved the problem with my old Compaq CQ 56. Once I find where I put the Laptop I'll follow your instructions.

Thanks Sorin . Great to see you & thanks for the knowledge. : - )

No worries... im sure someone was stumped by this... like you said, i would expect some beeps or blank screen... not power cycling. Ill keep this in mind if i run across a similar issue. Great content... thx for the video

this is a patient lesson for me.....thanks again for the lesson

Another nice video Sorin, it was good to meet you Friday. Keep up the good work.

Love you man :) Have a good weekend.

Nice to get a simple repair. Thanks.

Thank you Sorin for a nice video

Your new find of no start up puter just saved me with mine. All my laptop would do was blink slow on the power button. looks like it was either one dead ram slot or bad ram. Thanks.

(The upload)Video was flickering today Sorin. Good content mate.

Thank You. You have good channel!👍😀

Thank you very much for this video, it has helped me a lot. I just have one question, what do you think damaged the RAM?

I do now it this problem . It is new for me. Normally the memory ram is never broken. You have long warranty on the ram memory because they normally never break. Sorin thank you for the great approach to finding the problem. It’s not a waste of time for us. BBQ 🍖 was great

Enjoy your video, love you great man.

Good to be back and I got some new stuff to watch iv been away for a while. so i got a lot of new material to catch up on. hope all is well. got lost in apex from one of your older vids. took nearly 400 hours of apex to get back. ha. i got you to thank for introduction to game. i never even knew about it. tuff game to play with a hotspot and a garbage gfx set. looking hot in london. hot up north to. who the heck takes a acer laptop in to get repair ? chuck in garbage and buy a good one. :)

Hi Sorin Enjoy your videos, very informative and down to earth. Just a quick question I have an dell inspiron 1525 board which does not come on and I have found a resistor that is getting really hot but I can’t find any information on what it’s value should be , From what I understand it normally has a three digit code on it but this just has 1.5 on it. I look forward to any help you can give me as I am a novice at this. Keep the videos coming .

Very suitable class ever.

Sorin I think you forgot to plug in the speaker cable you pulled off while removing the back cover. 😀

How did you know the voltage input/output of every semiconductors? Do you have the schematic diagram? Or the values are just written on the motherboard?

Love the videos but think you forgot to reconnect the speaker?

Don't be unhappy sorin, you reminded us not to trust the ram. Yes it's been a rather hot u.k lately, a change from rain all the time lol.

I have seen all kinds of weird issues from bad RAM, it is something I always suspect.

Can you do a video on inside laptop supply voltages e.g 1.5V or 3.3V or 5V or 19V and what sections of the laptop does they power up..

Thanks sir

did you reconnect the speaker wire?

Excelente vídeo.. Computer repairs its a hobby that I have bean doing for some time.. By charging some jibes it anables me to upgrade e by tools.. Just got a mothen laptop hp slim Silva I believe ddr4 with exactly the same problem.. I will nead to by a ram stick because I don't have any DDR 4 spars and I will by a new stik for testing.. Wish you well

So you did have to remove the back cover again to connect the speakers .

I had the exact same problem today with an HP!

thank you

Sorin, I have a Compaq Presario CQ61. The laptop only works on AC power if the battery is plugged in. If I remove the battery and plug only the AC acapter, the laptop does'nt turn on. Can you tell what is the problem? Thks.

I had the same problem the board does not support RAM memory because it is DDR3 and to the newer board should go DDRL 3 Sorin Plase lock that Ram memory what you tacke aut put it in another laptop should work.

I wanted to change the ram from an old computer to a new one but when i did the swap, and turned it on, only the fan started spinning fast and the screen would not load, so I put the old one back and now the laptop just starts the fan and doesn’t load the screen, what can I do?

please help.. i have lenovo 3000 G410.. issue is no picture on screen but the vga does just the backlight only.. i already replace the lcd flex and lcd but is still nothing i already reheat the the graphics but i think the graphics is fine what should i do

Ram is partially broken not a dead ram. When pc starts the graphic needs ram to show picture (because it is integrated gpu), but with faulty ram it can loop or in the midle of starting windows when it needs more ram the system will crash.

Nice one sorin, but I need you to work on any hp notebook or probook with blinking two different color of light isue....it's eng. Taiwo from naigeria

If the computer cant on, how to check whether its motherboard or only the keyboard? Because the on off switch on the keyboard

is that possible if my ram working on my asus laptop and he can boot to windows, but when i put it on my acer laptop, my acer show no picture, just black screen with the fan spinning, and everything looks normal except display?

Am acelasi model de laptop Acer Aspire, doar ca e argintiu. L-am cumparat defect (ecranul spart) de la cineva cu 40 de Euro, fara modulul de 4GB memorie si harddisk (altfel era 75 de euro) si desfacut complet in bucati de proprietarul dinainte care din cauza ca nu se pricepea a distrus niste conectori ZIF si niste cabluri plate. Am reusit sa schimb ecranul si sa-l fac doar touchpad-ul nu functioneaza inca, poate e defect sau cablul panglica e intrerupt din cauza excesului de forta a fostului proprietar. slava domnului ca nu a incercat sa-l monteze el la loc, era tipul de om care ar fi insurubat un surub lung pana iesea prin tastatura.
