How a faulty mosfet looks like - HP G60-214EM laptop repair

[@tinkmarshino]

I have been missing these video's Sorin.. I don't do social media or discord or crypto mining.. I am just a 70 year old fella trying to learn a bit about lap tops.. and YT is about all I use my system for these days.. and of course e-mail to keep in touch with the kids.. Thanks for all you teach my friend.. you are really a good teacher.

I like when you say "Let me get the alcohol"

[@electronicrepairservice2020]

As a senior tech, your fellow workers should respect you & your tools by keeping their hands off anything on your bench. Nothing worse than someone taking a tool and not putting it back where they found it. 🤬 Good to see you again. Look forward to every video.

[@tinkmarshino]

I agree with you.. I was a carpenter for most of my life.. And to touch another mans tools with out asking was just not done.. unless you were a complete jerk in which case a good fight would ensue.. But you are right.. respect.. you show your respect by not disturbing another persons area with out permission.. I am sure Sorin would give it but the point that you were making and I agree is you just don't.. Carry on..

[@asusladt7805]

Sorine,, te rog mai multe videouri. Nu urmăresc nici un serial la TV dar pe tine te urmăresc cap coada. Foarte captivant. Mulțumesc!

Sorin, we look forward to spending more time with you this way. With much respect

Hi Sorin i have also missed your videos ,i have been into electronics for over thirty years and still learn from you my freind.thank you so much.

welcome back sorin ..hope the family are fine .. great simple video regarding internal resistance explained well .. god bless to you all ....

nice to see you post again sorin , thanks for the entertainment , keep on fixing brother!

[@mariodistefano2973]

Hi sorin, pleased to see you again! I've seen a lot of your videos, but In this video, it seems to me that you want to say a bit more of what you actually say and do. Expecially in the moment you find the broken mosfet. Also in the voltage injection moment. You say "be careful" but you don't say to what.

[@knightwar3]

Mosfets issues never get boring thank you for your good work and teaching lessons

you have likely helped save hundreds of these from the worlds garbage pile, ( I have about 4 of these ) Thank you

Thanks Sorin, nicely step by step explained and hands on. Oh...yeah...I get crazy also if they (re)move my tools, that is very annoying.

Seriously hacks me off when I leave tools only to find they’ve been moved and I can’t find them. Puts me in a mood for the rest of the day. Especially because I buy all my own tools.

Yeah well I don't need other people to lose my tools; I can do that very well all by myself :-)

hello sorin and thank you for all your video's....why you can't test the mosfet if it is shorting or no out of board !!

Finally we are back

[@maxwarfield6699]

At 13:09 you appear to be placing the the test leads on pins #3 and #7 [source and drain, respectively] of the first mosfet. Then on the second mosfet, you place the test leads on pins#2 and #7 [source and drain, again] BUT at 15:15 you say to test a mosfet, you have to connect the gate to ground [I’m assuming that you mean: place the red test lead on the mosfet’s gate and the black test lead on a ground point, right?] so, which is it? I’m confused by what you are saying AND doing. Please clarify. Thank you kindly

[@fendularatsq2317]

people asked you some very good questions in this video, nice going guys!

[@maxwarfield6699]

Perhaps, you can explain what we saw in this video, to me: At +/- 8:50min , when the injected voltage [19.6V] falls to 3.72V, Sorin says that the internal resistance of the short [?!] is high, so the probability [of the issue] being a capacitor, is very low, “ …and the voltage is quite high” so, it’s probably a mosfet. I have a few questions: 1- When the injected voltage [19.6V] fell to 3.72V, how can the resistance be high? 2- When the injected voltage [19.6V] fell to 3.72V, he says the voltage is quite high [?!] so, it’s probably a mosfet [?!?] . PLEASE explain what he meant - I’m still a novice in electronics, but does ANYTHING in this video make sense, to anybody? PLEASE clarify. I truly want to learn. Thank you kindly

Good Day, I have find your videos very interesting. I am currently learning electronics. I have an HP DA0U93B6D2 REV:D motherboard that doesn't power on. When plugged in, the power indicator light is on. When I press the power button, the power indicator light goes off and then returns but the system doesn't boot. Can you advise how could approach my problem

[@danielsaturnino5715]

Nice. Thank you

[@mohamedtopic5536]

I love you so much and I learned a lot from you, but I hate the profession in shops. People suspect that we are thieves and want you to fix while standing in front of them. It's tough. I love this area, but inside the shops is a curse

[@maxwarfield6699]

I don’t understand why at 8:43 you say the issue is most likely a mosfet. A mosfet controls the current flow [in a circuit] depending on the voltage it gets/or is provided. So, why/how/what in this case, makes you say, it’s most likely a mosfet problem? Are you deducing this, from the fact that capacitors let current through and in this case +/- 2 amps are flowing in the circuit, without problem? Please explain, I want to learn. Thank you

[@daffyduk77]

True, basic maintenance sucks with this model & the similar HP ones which follow the same pattern

[@ohmware2020]

why u did not change the mosfets driver? piernov and dexas says always replace the mosfets driver if u replace any of the two mosfet- the high side or low side, except for dc in

[@belaircomputerguyllc4001]

I didn't know you could just swap in mosfets from other boards. I thought it had to be the same part number mosfet as there are so many architectures.

[@fisforfriendship6093]

I'm no expert but I have to assume he used his experience and took liberty believing the high side Moffett to be around the same power rating/heat etc to start the laptop. Probably he read the letters

How you always have hot bad part, I made 3-4 graphic cards with shorted mosfet and when injected voltage never getting hot. My power supply has protection but same as yours,voltage drops and amperage increase... Wbr

PLEASE explain what you mean - I know I’m still a novice in electronics but now I think I’m also going crazy trying to understand, your logic.

[@tomeczek88]

Sorin question, can it be ANY mosfet? I see you din't even check the specs of the mosfet you are replacing, how do you know it will work? I mean the model number on it has to mean something. I find it confusing that you can just choose random mosfet and it will work

Hi there , at 16:40 , what is meaning of high side mosfet ? thnx

[@mm0077]

High side connects between +V and the load Low side connects to ground, which means the load is between +V and the transistor
