I want an exact number of how many laptops have turned into waste because of directly soldered CPUs. A socket is a bit more bulky, but present ones can be improved to get slimmer, and then you have a reasonable option to get the laptop fixed.

You won't have enough pressure from the cooler to keep a cpu in an LGA laptop socket unless you use a proper retention arm mechanism which is huge. LGA by design has a 10cm by 10cm ish area around the socket where you are not permitted to place any components. pins like old ryzen and such are too thick and long. This is why you only see socketed CPUs and mxm GPUs in very large laptops from say, Alienware.

Good job mate 👍

I had the some issues after having the thermal paste replaced and not powering on. What I found out is that sometimes you need to reset the battery by inserting a metal rod in the small button that is located in the bottom of the laptop. Although in this case it can be a permanent CPU damage situation

I have the same Predator 300 17inch 2070 super model as well for about 3 years now. I have in the past few months began experiencing issues with the CPU. I believe it’s a overheating issue. Haven’t figured out completely why or how to fix. While playing games my laptop blue screens and has to be manually reset. Laptop works if I have a fan on it and it’s elevated off the table. Very unfortunate that CPU failing seems to be a common issue with this model

Hi Alex, as i have told you for another type of laptop, but i don't know if the question can apply also in schematics with DR Mos, when a power transistor especially in the cpu supply fails, one can ask himself if it is working in couple or more with other transistors / dr mos, if after a test the short comes back on one of them or more, then one can consider changing all the couple or all the dr mos feeding the CPU... this is resulted to be resolutive in many cases... i have never repaired a dr mos pc, nor i'm a professional, i would like to know your point of view.... bye from Italy... i respect and follow you...

Hi Alex check under scope left mosfet solder pads, they seem darker

Have a question for you Alex....The Asus laptops that you fix with the Mos-fet issues, do they hold up? Are there any returns? I´m not underestimating your work in any way but still wonder if they are coming back. I`m thinking if there is some basic faults in the structure of the motherboards?

Hello, you repaired so many laptops, could you please guide me: what is your opinion about best gaming laptop motherboard? which brand is the most durable components and good design for their motherboards? If you want to mention a gaming laptop brand, which brand and model would be your personal recommendation? All gaming laptops stop working as soon as they receive very little amount of static electricity on the motherboard and short circuits happen almost all the time. which brand you think has the best components and design on the motherboard that can survive shorts?

I’m interested to know when a mosfet dies what the knock-on damage is likely to be ... I’m guessing some manufacturers design in protection and others don’t. I noted the fuse hadn’t blown. One thing about the ‘work smart’ quote ... my old boss used to say “work smarter, not just harder” ... that one extra word makes a big difference.

Mosfet can kill cpu. Which is most likely what happened here.

You may not get a conclusive result. You can get 2ohm and CPU is dead, and you can have 2ohm on a working CPU. Unless it is 0ohm you can't be sure the CPU is dead.

I don't know about acer but I had a familiar problem with the fans on a hp laptop. After I took out the battery and pushed the power button for like 10 seconds, it resetet the bios and after that started normally at least.

Very good job 👏 👍 👌

if i would be working on a device that is my device i would be taking shortcuts.. if it was for someone else i would take the utmost care and not take any shortcuts, striving for perfection.

Changed a different mosfet to the one that was diagnosed as shorted.

Hi After replacing the Acer Predator Helios 300 Laptop LCD Panel, the Charging Light does not come on at all. There is no power to the laptop. At first the blue light came on and then unfortunately it went off. Many people on the Acer Forums experienced this problem after replacing the screen. Most of those who experienced this problem changed the LCD screen without removing the battery. Could this situation have caused a short circuit on the motherboard?

Hi I have a laptop the same and the customer has replaced the screen so they didn't take the battery out after that laptop did not turn on I checked it has no 5 or 3 volts and replaced the charging BQ7480 but it is still the same any I idea please let me know

There is a 50% chance of repair if a VRM died. The package has 2 mosfets. one to ground and one to 12 V. They switch alternating to get an average of 1.4 or whatever volts. If the mosfet to ground fails first voltage goes to 0 and no harm is done. If the mosfet to 12 V fails then the CPU gets 12 V and dies and the other mosfet in the package will die too. When you get it for repair, both are gone so you can't tell which one died first. Depending on which mosfet died first the laptop is either fixable or a no-fix. The odds are 50%. If you are lucky only a capacitor shorted, then the odds are very good because they connect to ground.

There should be the Predator splash screen and sound when turning on

Whatever you find on that predators laptop, send it to the police.

You should try again a couple times before giving up. Could be BIOS or Windows "re establishing" itself? Sometimes requires several boot attempts, depending upon the last state it was in when it failed.

Nah, things like bios reset or memory training would auto-restart when they're done, and anything to do with windows would still show a post screen first. If it turns off without posting, it's a critical hardware error (CPU, GPU, RAM) because the SMC and power delivery is working (charging light, keyboard light, power on sequence). It's very likely that the drMOS failure fried the CPU, so there's no point to troubleshoot more. I'm sure he tried to power it on a few times with the same result.

Here we have a NOT Asus laptop

This one is very interresting for me because I have the same laptop as the customer, The only difference is that my laptop is a newer version of this one. My laptop whas send 8 months ago back to acer with a problem also on the CPU. they replaced the whole motherboard under warranty, but the poblem whas something with the CPU sensors.
