High End Razer Blade RZ09 Laptop Repair. Another Shop Refused to Fix.

[@staples4335]

Was yelling at my screen saying the other ones are cracked! Lol. Also looks like alot of heat has discoloured the board around that area.

[@ejeckk]

I was looking and was like, "Alex, there's a giant crack in that chip."

[@richgame2331]

i'll be honest, there is little chance that CPU isn't blown with how much damage the mosfets took, but you never know ! Good luck with the fix, will definitly look out for the follow-up !

[@Slippydidipp]

The outro is better than factory 😅. Thanks for your videos and the offtopic tips and tricks. Calm voice and you are on point, i appreciate it. 🎉

[@swoopulater]

it's sad a company won't deal with you just because of your name, i always liked dealing with digikey but now i'm not so sure i want to knowing this. Like others have said there are other vendors that won't discriminate over something so trivial. Am curious to see how this one turns out. Nice job alex

The next question, did something overload those MOSFETs? Perhaps a massive short after the MOSFET? I look forward to the final chapter of this repair. Thanks Alex.

[@filips7158]

They deliver 60A peak, that is essentially short-circuit current for a 1.8V rail. Their normal operation is short-circuit 😅 no wonder they fail.

[@bblod4896]

@@filips7158 But, at least two failed so bad the IC cracked like the San Andreas fault. Was it a short after the MOSFETs or poor engineering? Hopefully, we will find out in a few weeks.

[@l0x4gpt]

​@@filips7158the 60A rating is often way more than enough for the CPU; the rating is that high to withstand the heat produced by high current demand; the power circuit being multi phase means the thermal capacity of the MOSFETs are even bigger, thus you hardly can overload those MOSFETs at all; mostly i suspect they are killed by transient spikes - the immediate death

[@l0x4gpt]

​​@@bblod4896correct me if im wrong but you cannot destroy the drivers like that by just applying a short circuit. something even worse probably killed them

[@bblod4896]

[@Suresh_Pillai]

Excellent work Alex. Board might have already gone through high thermal state. Depending on four or six layered layout, there may be strain on other underlying layers to brittle.

[@Nobbie248]

Thats probably why it was a no fix from the last tech

[@marisbarkans9251]

Yeah i also thinl how did they crack, seems like the board moved or heat expansion or something but the board underneath shoupd be the same cracked no? Or maybe since its a 60 amp chip mayne by itself in expanded from heat.

[@holyhelga]

I wonder did the last repair shop see the broken chips and didn’t want to replace them

[@billykulim5202]

the clue is the repair local shop did not find the cause, so the shop is not true repair shop with skill and equipment like northridgefix......maybe simple troubleshoting shop

[@holyhelga]

@@billykulim5202 yea true you do need knowledge and equipment to actually do board level repair

[@BigEightiesNewWave]

Funny fuse has big X. Skull/Crossbones would be good too.

[@Ink_and_Motion_Studio]

Is there a particular reason why so many "repair shops" seem to deam many small circuit repairs like this as "unrepairable" (even the very own manufacturers) , yet you manage to figure it out relatively quickly in most cases and then just proceed to order the needed parts or use in stock donor parts. It seems so ilogical to refuse a repair unless it really is a case of a completely dead item with no true possible way of repairing it. If it was possible, geographically, to work/study under you, I'd love the chance to. You seem to be vastly more equipped intellectually than so many other "pros".

[@blackrifle6736]

*Um. How about laziness, ineptitude, lack of proper diagnostic equipment and processes, etc. The list could be quite long. Cheers!*

[@instahawk8422]

Inexperience is a big factor and if they do attempt it they would mostly likely do more damage making the repair a longer process for a professional

[@treeoflifeenterprises]

Not everyone has the skills and experience of Alex, and his time is worth money. the econonics and risk and time of component replacement means there are not many places that will do component level repairs, so if module level is not economic, the repair shop will say so, and charge a basic fee for looking at it.

[@Oheng75]

Bc often it's not economically. The bulk of broken hardware is valued at only 100-200 euro. NRF gets sent high vaule repairs from even outside California.

[@Machistmo]

It’s a Razer.

[@DrivenDIYer]

Love your videos. I don't know how to set up Multimeter for those measures, ca you do a video hot to measure caps, diodes, mosfets, resistances with Multimeter. Tanks!

[@mrBDeye]

There are plenty of KZbin channels that already explain the multimeter and how to measure components. You should take a basic electronic course at your local college.

[@saydmarschany8321]

What happened with DigiKey?

[@picasso821]

Let us know if replacing those faulty Dr Mosfets fixed the problem???? I got Asus F15 with exactly same shorted model of Dr Mosfet, just ordered it and hoping after replacing shorted mos it will not turn out to bed dead CPU. Thanks for the quality content. Cheers. EDIT: Dr fet replaced and my laptop is alive :)

[@marisbarkans9251]

Oucan do voltage injection also with just feeling the board right? And am i right to conclude that you would inject voltage at the location of the short or woupd it change from time to time?

[@laserspike]

LOL, was wondering when you were gonna comment on the dirty great cracks in those chips 😀

[@cyberkiller83]

i saw those cracks from the beginning jajajajaja. Nice diagnose.

[@AndrewFremantle]

It's a shame there's no way to see if the CPU was fried before spending the time/effort sourcing and replacing the power delivery ICs. Do CPU power rails ever go short-circuit when they get zapped?

[@Neo_AIO]

Depends on the generation, recent ones have so low resistance that you can't even figure if it is shorted. Some old generation had up to 18ohms of resistance and measuring something lower than 5 ohm usually meant dead cpu . You have to know your generation specs to figure out if the chip is still good 😅

[@FrozenHaxor]

It's only possible to see sometimes, and ideally when you have 2 exactly same boards to cross-measure. Usually it lowers the resistance just a little bit, haven't really seen them go full blown zero ohms. It's a crap shoot and I reject repairs that have had B+ gone straight to CPU through shorted MOSFETs. Haven't had one case in which the CPU survived. Those power supplies in gaming laptops deliver upwards of 12A at 19.5V, CPUs are going to lose the battle each time. Some technicians get lucky just to have a comeback because the CPU will die later on even if it survived the initial zap.

[@supergeekjay]

@@FrozenHaxor I hate modern laptops. If CPU's were still socketed we wouldn't have so many issues with rejected repairs. BGA is a nightmare. Everything soldered to one board to save a few MM on the machine thickness.

Can you inject voltage into CPU itself and see it is is a short before ordering new chips ?

[@CompaGoon]

Alex how do you measure voltage drop?? are you still in diode mode? very new to this. keep up the good work

[@TechProFury]

Yes, best to use red probe on ground when using diode mode, unless testing a diode directly.

[@loudeal8668]

Genius Alex your the best

[@TechNinjaHS]

What would cause a chip to crack in half like that?

[@Steffen_]

to much heat

[@swoopulater]

if one shorts internally it will heat up and cause the chip to expand and crack at the point of the short. makes me wonder if the person was doing some OC'ing or just some heavy gaming. Some of these games do tax hardware quite a bit.

[@l0x4gpt]

​​@@swoopulater those are 60A drivers, and the whole power circuit is multi phase (60A x # phases) so i dont think heavy overclocking would cause such an issue like that; more likely its some very bad transient spikes that immediately blown the drivers when they happened

[@bobby9568]

[@Healcraft]

naw CPU and GPU have very high amp requirements these days, if you think of the voltage around 1.XX and they run at , well for this laptop total probably 100-200 watt then yeah. RTXD 4090 is around 1.05 volts, and runs at 350-400 watts under full load, so yeah you will be needing quite a few drmos outputting alot of amps. and as he said the 60A drmos probably only continuously are used for 10-20A otherwise they would be too hot especially in a laptop, but then again they did crack. Remember Volt X AMP = Watts

Today I had to order EC IC for HP laptop because it is nowhere else available than china. For those curious why - customer came in with HP 15s laptop, it's 2yrs old. It powers on - blank screen. By measurments etc, board is completely fine and so should be APU. First I tried few bios dumps to see if behavior will change - no change. I prepared bios with forced prog factory mode and it displays picture, flashes internal bios blocks and EC chip, then after reboot it goes dark again. I told customer that last thing I can do is replace EC chip and if that still doesn't make it post then most likely APU is damaged and so far I see no chips to buy, and no spare boards sooo nothing good for customer. I'll do followup comment in few weeks if this thing worked or not.
