Most common fault on a Dead Laptop

[michaelforde]

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

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'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 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 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

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 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!

I'm am new to computer repair. Followed this video and it was excellent!! Everything had correct readings... light turns white but laptop not working without battery. Can charge battery fine only with laptop powered down(orange light on). Will not charge while powered up or with power supply and no battery. Light does come on white but can not use unless battery is charged up. Then dies, and charges again and so on and so forth.

This worked for my hp probook 650 G2.
Was ready to throw it away and wanted to try this repair as an last effort.
To open up the laptop and put everything back together is most of the work.
Measured voltage from power jack input, step by step, component by component, and the first mosfet seemed dead.
Made a bridge from small piece of electric cable across the mosfet, with use of solder iron... and guess what. Fixed!
Super thank you for this video!

Oh my gosh I finally found the best laptop repair website in the world! I was about to throw away my 2 dead hp laptops and about to buy 2 new ones but now it's working. I fixed them through your awesome tutorial. Thank you so much. I saved $600.00 today.

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

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.

My grandma’s tower was running slow after 10-15 minutes of it being one. It had blue screened on her. She called me up asking what it could be. Told her that it is usually related to hardware, drivers, or a virus. Ended up being that the heat sink was wearing an alpaca sweater and was over heating. I still ran a few checks on the ram, hard drive, and ran a virus check just to make sure.

I had an old laptop went totally dead on me. I studied it and checked as much as I could with voltmeter. I studied and noticed that some of those tiny little resistor blocks that are surface mounted little bricks with no wires have numbers of their value ( very tiny ). I noticed some near power input were marked with 0.0 which I guess meant no resistance or some kind of jumper. I found one that didn’t seem to be ‘ jumping ‘ like it should so I managed to solder a small wire across that part of the circuit and ‘ voila ‘ it’s alive again.

I am a surgeon. I use operating microscope to to anastomose small vessels and ducts. I am impressed by your use of microscope and peaceful demeanour in approaching the issue at hand. Any work that is done at peace is like a meditation. I recommend this video to anybody who wants to reduce haste from his life. Regards

We used MOSFETs and other "surge suppression devices. Usually, they are not needed unless you have AC power that has a lot of surges and or lightning. Most of the time, just putting a good surge arrestor at the input to your building is plenty of protection.

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!

[wefukthenwo]

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!

[KingLuseer]

I don't know how people can dislike Your videos.You passing Your knowledge to us in this short videos that You been learn thru years.That is just wonderfull.Thank You very much!
