Re: Caps and how to find one to replace
Also in my schematic i have different capacitators which i want to buy, but im not really sure what to buy.
0.22U_0402_25V6K
0.22U_0402_16V7K
1U_0201_6.3V6M
0.1U_0402_25V6
I can read up to voltage rating, but what are those K and M at the end? Or regarding the last one, there is no letter.
Can anyone explain me? -
Re: Caps and how to find one to replace
Yes without schematics im able to find what to buy.
But lets say i have a couple of dead mobo, and i want to take some capacitators and put them on another mobo im fixing.
Is it possible to recognize them without schematics?Leave a comment:

Acer predator 300 LA-F952P DH5VF
Hello everyone. I have bought this laptop which was broken. I dont know what happens, but when i got it i saw much oxidation and maybe some water, but im not sure.
I cleaned it all, and what i achieved is that now it turns on, for like 1-2 seconds, then it goes off, and try restart once.
Sometimes when i leave it without power, i turn it on and it keeps like that for 10-20 secs, but no display at all, then when i try again to turn it on, again it goes for 1-2 secs and thats it.
I saw there is 19v on first 2 mosfets and also the current sensor, i also...Last edited by Vesko356; 06-10-2023, 01:15 PM. Reason: Attached schematic removed and replaced with link. -

Re: Stepdown ASUS s530FN
Hello Mon2, thank u a lot for the answer! I already ordered it.
But regarding the mosfet in the link. How did you find it was QM3092M6?
Id like to learn. Because the label was m3092m. What does this label mean, and what does qm3092m6 means?
How did u find it?
To explain, i would not have buy it because its a different label.
Thanks a lotLeave a comment:

Re: Stepdown ASUS s530FN
Thanks you a lot Mon2.
I also noticed that a mosfet is gone. on schematics i have PQH8701
On the mosfet itself i have m3092m 84687e.
I found something only looking for the mosfet's label.
Can you address me to what to buy regarding it?
Thank youLeave a comment:

Stepdown ASUS s530FN
Hello everyone. My laptop is dead, and i found out that the Stepdown is gone.
Im trying to buying a new one.
This is what i get from the scheme:
RT8249CGQW
And what i see on the IC itself is
2n=5j
J05
I see many stepdowns online to buy if i type RT8249CGQW but noone has 2n=5j
Most of them are 2n = 2j or other stuff.
Can i buy them?
Also, can anyone explain me what 2n = #J means? -

Android ONEPLUS 6 CPU Reballing
Hello everyone.
My oneplus 6 just died without no reason. I was using it and suddenly it shutted down and cant turn on.
Checking around i tried to reball with hot air station (no BGA station).
Im stucked. Since im a newbie i was just trying and im afraid i used the hot air station too much.
The CPU was a mess, so i tried to scratch it to see again the pins.
This is what i have now.
Is there anything i can do to try to solve this ugly thing, or its just impossible and i have to throw the phone?

Re: Asus sf530f and Inductor 2r2
I attached the multimeter manual and his ranges. As i told u its an auto ranging.
Also the measurement picture. its 01.1 ohm between gate and source.
drain is the 4 pins which are connected all together below the mosftet right?
In that case i confirm that i tested gate and source (pin 1 and 4)...Leave a comment:

Re: Asus sf530f and Inductor 2r2
I just removed the mosfet. On pads there is no resistance.
The mosfet itself gives open line when i measure resistance after being removed.
Now im confused.
Btw the first mosfet on the main power line has right input but no output.
So i inject current, and thats how i found the mosfet we were discussing in the previous replies.Leave a comment:
