That's a lucky case, I got from my mate gaming more advanced laptop 2500 pounds worth and there same burned first MOSFET + burned all round cells inside motherboard and burned so far and deep, there's no way to return to life that motherboard. Thank You for video - top man 👍
I think that charging a fixed price for repairs is a good idea (you mentioned this yesterday). It wouldn't be fair to charge 4 hours for yesterday's repair and then today's customer pays 0.5 hours for the same fault.
In the past these sorts of jobs are used to cover the price on jobs you lose money on due to excessive hours you can't charge for.This is obviously at the discretion of the repairer.
its not often that simple!!...it depends on many reason how to fee a repair job! in some cases u find the problem fast and the parts are cheap, so u can fix it for a good price for both sides! but if u are not able to find the issue in the first 30min and the parts are relative expensive, so u cant charge a fair price for all! there are many many Shops that never repair cheap 300$ Laptops from Intel 4th Generation! the reason is simple, you can buy it used for less than a repair would cost u. Sorin is one of not many Repair Shops, that try to repair most devices!
Perhaps not. However, consider that as ones skills get better, faster, more efficient, you charge 'more' for that service. Unlike technology, where prices tend to come down as manufacturing processes become more stable and efficient. So, technically, one could charge 'more' for a job that took less time - even though it now appears to be a simpler repair. Food for thought.
i dont like random shutdown cases, it can be various things not just shorted mosfet besides shorted 5v power rail, faulty Super IO or faulty southbridge...etc.. sometimes it opens and shutsdown after 3 seconds and this faulty you can also check every mosfet with oscilloscope if there is leakage one of them or not.
If you are already familiar with common acer failures, please include this manufacturer in your list of laptops that you are happy to receive for repair. Of course, use surrogate part numbers for those Mosfets from a reputable (trustworthy for quality) manufacturer. Finally, don't forget to buy a British lottery ticket. All the best.
I now have the same problem on my replacement laptop (after 4 years) but only with videos with a higher resolution, the CPU goes up to 80% and then it just shut down. 😞
Yesterday's fault was a warranty return, which started with a shorted capacitor, yes? Is that capacitor still the issue of why these mosfets are blowing? Or do we just replace the mosfet? Thanks!
I suppose maybe the first mosfet is a much higher rated voltage device and maybe the second is lower voltage breakdown so it can be smaller. The on resistance of these modern mosfet is incredible low.
I have an Acer VX15 very almost identical to the "Nitro" but with the ac plug on the side. Sometimes I have it unplugged working only with the battery and even when still having a big percentage of power all of the sudden the PC shuts down by itself. And when I try to restart it by pressing the "On" button it doesn't turn on. So I have to plug the charger/adapter and then it turns on and boots back up. I assume it must have a very similar problem with the mosfet. My problem is not severe since I can keep using my PC but eventually I might need to check it. One thing this Acer VX15/Nitro has is that the keyboards have problems by not able to type certain letters. I already got a new keyboard and will install it soon.
So what is causing those mosfets to burn out? Is the voltage of the charger being too low or fluctuating or is it gaming with high ambient temperature?
Luck is on some people's side. I consider myself last in line when they handed out luck certificates. They say you can buy your own luck. Says the lucky ones.
so i just had this problem with my laptop today were when i woke up and started it up it was all fine then it just shut off completely and ive tried to start it back up but nothing has worked any ideas on how to fix ?
you can see its same setup that two laptops same place power jack same place mosfets ... etc... they just changed name and its maybe amd vs intel or something like that i asume :)
Hi. I have been repairing laptop for a while now. But my problem is, I can't avoid breaking some plastic clips during disassembly process, no matter how careful I am. Is it normal? Well I normally could attach them back, but I need to put extra hours to fully repair the laptop. Any tips?
@@David-Zita well, some manual have limitation. For example, when opening cover for screen, there's no various way. It's the same method. Older laptops tend to have fragile plastic clip due to the age. It's just very tiny parts that being broken. That's why I want to know if it's normal for technician? Sometime that situation cannot be avoided?
@Ratata JK: You must have the right tools for disassembly. I was skeptical to use plastic tools (screwdriver, spudger, plastic opener pick), the cheap ones to open cell phones (of course I prefer metal) but there are excellent ones (quality) for use on laptops and TVs. Of course we damage plastic hooks on the covers especially when one is a novice, that is, the first time you face each manufacturer. I don't know much about the plastic injection process (the chemical and mechanical engineers are responsible for manufacturing and molding) but the quality of some manufacturers leaves much to be desired. Another way of saying it, how is it possible that large screen TVs (50 inches or larger) DO NOT leave plastic ventilation slots on the back cover, mainly where the LED strips are installed. Look for polymers for electrical appliances. You will find that its main enemy is the internal heat generated by the components... of course the environmental conditions of the region where you are also influence. In my case, the summer temperature is above 40 degrees Celsius every day and leaving plastic exposed to the sun will deform it in less than one hour. Breakage of plastic cover due to hinges on laptops? It is another topic. Finally, superbonder 480 black, original loctite glue (an industry standard) can successfully solve that problem of broken plastic hooks. All the best.
since i have a ocd on scratching plastic surfaces on deviices mines or not often i dont have much problem regarding this but my issue is im weak and not too much pratice in soldering haha
Sorin, killing the laptop during software installation? Don't you have enough work than having to fix a broken windows installation? You should wait till the installation is finished OR cancel it. But NOT kill it during a running setup. Hell no...
It's great that you got the same fault the next day. I bet you won't see it again for ages, forget about it and change the power chip again 🤣🤣🤣 Only joking.

that's where experience come from repeating lol . lesson learned , looking for the next one, thanks for sharing as always.
It's like waiting for a bus, then two come together 🤣🤣👍
you make up for your labour today sorin im glad for you ...
Nice, learning from mistakes and re-applying the knowledge on the next job what was learnt. Life lessons :)
Quick JOB. The wisdom of experience. TY Sorin
No Sorin it's the bios...😅
thanks for the video. I laughed as I remembered the past repair, how can go wrong way for some reasons.

Acer should recall and replace! Obviously, there is a high probability more of the same models are affected.
Yes they should use thermal pads on it
thanks for the lesson Sorin, keep it up
Yes Boss, experience is the best teacher
experience is the greatest teacher
Tricky because why check first 2 mosfets if 19v power rail is present. Good to know now!
That's why is important to learn from mistakes 😅😊👍
Esti un om norocos 😃😃😃

The waste of time from yesterday compared with this one ☝️ better check the mosfet 😂 thank you for sharing

I’ve got in an acer laptop at present with short, so will see if the same

Merci beaucoup maïtre votre travail ils nous aides enormément bonne courage merci
He's trying to say the 2nd MOSFET is a lower power "rated" part, ie, smaller/weaker.
You should buy a lottery ticket.
The treasure of experience
Makes me wonder about the acer power bricks. Maybe sending dirty power to the laptop if this is a common fault.
I do wish I could understand this thing. So interesting
Good job mate 👍
Wonderful...well done
So what is causing those mosfets to burn out? Is the voltage of the charger being too low or fluctuating or is it gaming with high ambient temperature?
I recognize a glitch in the Matrix when i see one
AMAZING
Acer gaming laptops have a lot of problems with caps and mosfets
Yes, I am not buying another acer no matter what.
Simply we can fixed all things
Probably get more now lol well done Sorin
Is it possible that the ac adapter can be causing the same problem on many of those similar acer models?
Was it just me or did both of those laptops original soldering on the two MOSFETS look terrible to start with. Is that the common makers fault.
Somebody has seen the first video and has brought you the second laptop...
Luck is on some people's side. I consider myself last in line when they handed out luck certificates. They say you can buy your own luck. Says the lucky ones.
That was an easy £100, will pay for the time you wasted on yesterdays one 😂 Nice one, well done!
u were hit by the mystery of quantum mechanics... i do have these a lot in my bussiness, within 2 days people come with the exact same problem..
Sorin, how is it posible that you only have 19 volts and in those mosfets gate you have 26 volts?
If it's the same owner, ask if they have an ionizer in the house. ;)
Hmm... Maybe ACER used a faulty mosfet batch?
What year-make was the previous job vs this job?
Wouldn't be the first time that company has used cheaper parts. Their power supplies and related parts seem to fail pretty often.
Yes sir, the job is done.
Time to stock up on those mofets!
Well done sir
Which software are you using to stretch the CPU
cpu z
What happen if you just remove the mosfet and just jumper it?
this is a known issue with Acer
so i just had this problem with my laptop today were when i woke up and started it up it was all fine then it just shut off completely and ive tried to start it back up but nothing has worked any ideas on how to fix ?
Replace the 2 first mosfets 😃
This fault found easily is good karma ! hahaha
you can see its same setup that two laptops same place power jack same place mosfets ... etc... they just changed name and its maybe amd vs intel or something like that i asume :)

try to find service manuals that should help you how to disassemble the laptop carefully without breaking some plastic. good luck

What are the odds?
wow amagin
Karma for the unpaid warranty repair you did yesterday!

en la física térmica, si querés disipar la temperatura de una superficie mas rápidamente, podes aplica el thermo pad en un area mas grande de la placa
Like a deja_vu 😅
This laptop looks a little bit sus.
wow fantastic sorin ez job hehehe
Hi Sorin, what do you think is causing these mosfets to be shorted?
The heat
@@electronicsrepairschool or maybe buying parts from weak suppliers
Learning by repeating. Haha, what a coincidence. 😀If every day was so easy now... 😍Unfortunately not 😞☺☺
🌹
to many gaming laptop repair :)
Electronic university?
Amogus
Lol!
Cool..."Where are my Mosfets.."
It's great that you got the same fault the next day. I bet you won't see it again for ages, forget about it and change the power chip again 🤣🤣🤣 Only joking.
Acer must be sued.
Don't buy Acer.
Sussy
Looool!!!!!
