ASUS ROG MAXIMUS Z690 HERO - Component identification
Hi Folks
I got an ASUS ROG MAXIMUS Z690 HERO mainboard with missing components on the backside near the HDMI output.
Unfortunately there is no documentation available nowhere for that board, I did also not find any similar ASUS board design. Even Russians nor Chines have anything available here (nor BV, nor schematics), so only way to discover the parts is from a real physical board.
On the picture left the area where the missing componets are is shown.
On the right picture the detaileed view is shown.
It seems that a double mosfet is missing, probably...Last edited by DynaxSC; Today, 04:49 PM.

Gigabyte R9 390X
Good Day to All,
I hope there is someone that can assist me with my GPU. Is does not startup at. Zero fan spin. GPU not heating up at all. I have checked all fuses and voltages that I can find. The one problem (if it is even a problem) is a reading that I am getting off a mosfet. Between Pin 1 of L1014 & Pin 4 of Q4026 ( PS_VDDC_UG5_R) gives me a reading of around 645-650 ohms. Between Pin 1 of L1012, 1013, 1015 and corresponding Pin 4 on Q4020, 4023, 4029 all give a reading of 7.73kohms...

INSPIRON 5570 bios maddeningly slow
hi guys, i have dell inspiron 5570 with a maddeningly slow bios.
specs are: service tag 6MSTDP2 CAL50/DAL10 LA-F115P REV: 1.0(A00) CORE I5 with radeon graphics
When I turn on the computer it takes approximately 5 to 10 minutes to boot Windows, sometimes up to 15 minutes.
That slowness is visible even within the bios menu. It seems as if the clock frequency has been reduced drastically
I already tried some dumps that are in this magnificent forum, I also followed the tutorial by mr [B][URL="https://www.badcaps.net/member/237374-smdflea"]SMDFlea[/URL][/B] to...

T495s Bios chip location
Hi,
I'm trying to locate the Bios chip on my T495s 20QJ to recover the Bios.
The computer shut down during the bios update, now it's just singing. I want to try to reprogram it. I've read the BIOS guide but I'm still missing some information. I hope I'm asking in the right place.
Do you now which one of those chips is the BIOS ? And, are those compatible with the CH341A ?
Thanks a lot !2 Photos

I have replaced the psu on this Toshiba 42HL196 twice. I have no HDMI or tuner. The component and composite inputs work though. I had a spare seine but it just gives me 3 red blinks so it's either a faulty seine or needs programming. It would seem it's the seine board. Ideas?

Please Help. Hp 8460P Motherboard not turning on.
Hi All,
I have been struggling to repair a HP 8460P laptop. Motherboard does not turn on. I have traced the problem to what seems to be a missing signal KBC_PWR_ON causing Trip2 on IC 5006 (TPS51123) to be activated.
The following components have been replaced but the problem remains.
C5191
C5192
U50006
Listed below are voltages appearing on U5006 when the Motherboard is supplied with power from a bench power supply for the first 15 seconds or so.
Pin 1 (Trip1) = 0.65
Pin 6 (Trip2) = 0.65
Pin 8 (Vreg3) = 3.31

Lenovo Legion 5 15IAH7 NM-E241
Hello guys,
Got my hands on this laptop and started troubleshooting. The only thing I know is it turned off and never came on. No lights and not coming on.
Started doing some checks and found the main rail present everywhere. Something weird though as the gate of the first input mosfet is 3.7V and the output is 20.3V.
Tried to trace the gate and it looks like it's connected to pin 61 on the io. Is the IO supposed to monitor the gate voltage?
5V and 3.3V are missing from the coils. Found by lifting PL6202(on the 5V rail) the clicking fet sound goes...2 Photos

Fortinet 50E Slowing down internet throughput
Hello. Coming to you from the laptop forum. Have a client with the Fortinet 50E that has 320 Mbps as internet input speed but only 20 Mbps output on each and every downstream port (using FAST.COM to benchmark).
Reseller is stating the Fortinet is 'worn out' which does not sound logical at all unless the flash memory is 'worn out'. They, of course, want to sell another + onsite installation fees.
Can anyone share feedback on this unit? What can cause this sluggish behavior. From our knowledge, this device is snooping on the traffic to halt viruses / hack attacks, etc....

Troubleshooting Asus Tuf Gaming A15 FA506QM 33v & 5v rails
Hello!
I am still learning on laptop repairs and I am currently working on the above mentioned device.
Currently the laptop is dead (no power on). The device takes 2-3 mA when 20v are injected onto the charging plug.
Main power rail is present (20v), but no other power rail is present, including the 3v and 5v. I noticed that when no power is connected the 3v and 5v coils have large (normal) resistence to ground, but when I plug the power, both are being shorted to ground.
I wonder is that an expected behavior or there is an outer protection activated.
