Most common fault on a Dead Laptop

By carefully following this video, i have now repaired an ASUS laptop that has been dead for 12 months, thank you so much.

Im not repairing things for profit.. just super fascinated in how things work. I cant begin to tell you how much your videos mean! Sharing knowledge like this is such an honorable thing to do. Very grateful, always look forward to content like this.

I've been working with and on electronics for 45+ years, and what I love most about it is that I can ALWAYS learn something new, like I did just now! That was a very fine piece of troubleshooting, but the way you explained each step of your process was very educational. I came to this video because I also have a dead laptop, and I was pretty much out of ideas, but now I'm quite confident that if I follow along again with this video, I will be able to bring it back to life. Thanks for sharing!

im nearly 51 but but watching videos like this make me want to learn about electronics, id imagine there is a lot of satisfaction in fixing useful tools like this when they are broken

I have been watching your educating people on how to repair laptops etc and I must commend you on your patience dedication and generosity. My name is Ron and I am from Melbourne Australia and although I can repair a few things as a hobby, I have never repaired laptops ot Iphones. Your explanation and demonstration on repairs have inspired me to try to fix some things after I have watched more of your videos. Please ignore any negative comments from othrs and keep up the good works. There are plenty of us who appreciate you tireless efforts. Kind regards, Ron

I admire your courage in presenting your assessment on when to quit. Am retired electronic technician(mostly worked for corporations, never on my own business), so I understand your judgement. Nice video. Keep on trucking buddy.

Nice video! I only wish I'd come across it sooner. I like the guy's no nonsense approach. He quickly tracks down the issue, and solves it without fuss. I also like the way he's thinking about his customers, and his primary concern is to help them, rather than to make as much out of them as he can. I wish we had people like that where I live!

Sounds like the diode in the MOSFET died and kept the circuit from detecting the power supply. Yes, power has to pass through the diode built into the MOSFET before the circuit on the other side will turn the MOSFET on... Short the MOSFET for a moment and then the circuit will power the gate and try and turn it on. If the diode is dead then no initial power detection happens and no power on. It's a low resistance polarity protection circuit.

I love the simplicity of the way that the 8-pin IC Chip was removed and then (using calibrated fuse wire) bridging the Drain & Source in order to restore the 19vdc supply to the circuit.To say that the Motherboard is "complex" is an understatement! It is also extremely difficult for anyone to fully understand the full function of the 8 - pin IC Chip that you removed. Further to this, the pinout diagram would be needed - in order to ensure that you do - in fact bridge the Drain & Source. The IC device which was removed, handled the full current of the Laptop. There may have been the correct 'Gate' voltage present to turn the Mosfet on, but the device may have been faulty. I do appreciate everything that I have seen in this video, and I have been enlightened by your Tutorial. Thanks & regards from Sydney Australia.

Best laptop repair i've ever seen. Solid experience i may say. I learned a lot from you. Many thanks.

Toata stima !!! Tin sa multmesc pt toate informatiile pe care le-am acaparat din postariile dv!

4 years of studying electrical technology (technician) summarized only by 24 minutes video. Thank you it works for me

kudos.....thanks for the help!!!!! I love being able to get into the little fine spaces to diagnose and repair. Without your help on this issue i would have been running in circles!!!!!!! Thank you so much for the help!!!

Thanks for sharing your knowledge.

New to your channel, love the help I get from them! Thank you so much

Wow, that's really an amazing tech skills! I also have a dead laptop with built-in battery and trying to fix it. The video guides and gives some helpful hints what to do if someone has similar issue.

Just want to say thank you for all these great videos. I'm fixing an HP pavilion dv5_1235dx now for my wife and your saving my life over here!

I'm going to spend the whole day/evening watching all videos from the start. Need to reduce the pile of electronics building up (hoarder) and throw out the unrepairables, or keep them for parts salvage?! Grateful for the leg up he has given me. I just love this stuff!

directo to the point.....what a awesome technician you are sir....salute

What a Gem of a video from 5 years ago. I have a HP Envy with similar problem and this has given me the confidence to go and take a closer look at the Motherboard. All other things have failed, and it's got to replace the motherboard or scrap it. Very well explained bit of troubleshooting and fixing. This video proves even the simplest of videos can share some very hidden knowledge these days! Awesome!
