DDR5 Laptop Motherboard Tester
Quickly detects CPU shorts, open lines, and DDR5 slot faults.
LED indicators show fault status—off for open line, extra bright for short.
Test points like BULK,ALERT,HSA,RESET, HSDA, HSCL،POWER GOOD can be measured online.
Pin reference guide on the back for easy troubleshooting.


DDR5 Laptop Motherboard Tester – Detects CPU Short or Open Circuit & Slot Status via Light Indicator
How It Works:
Open Line (No Connection): The LED remains off, indicating a possible fault in the DDR5 slot or the CPU—this may also suggest the CPU requires reballing.
Short Circuit Line : The LED will glow brighter than the others, signaling a short in the slot or CPU area.
Important Test Points:
For advanced diagnostics, you can remove the tester’s battery (cr2032) and power on the laptop to measure key signals directly from the test points, including:
  • BULK
  • HSDA
  • HSCL
  • HSA
  • RESET
  • ALERT
  • POWER GOOD
These points help in verifying the integrity of DDR5 Power lines and communication between the CPU and memory slot.
Easily Detect CPU Reset Signal:
The tester allows for quick and easy detection of the reset signal coming from the CPU, helping you verify whether the processor is initializing properly.
LED Indicator Pin Reference:
If any LED shows abnormal behavior, you can identify the corresponding pin number by checking the label on the back of the tester. This allows for easier troubleshooting of specific signal lines or faults.

Clear BIOS Asus Rog G531GU

Hello! Hi, I dumped my password protected BIOS. I flashed a new BIOS from this site (https://www.alexlaptoprepair.com/forums/threads/asus-rog-g531gu-g531gw-1-6-bios-dump.3918/), and everything works fine. I don't see the Mac address and PC serial number available on the BIOS screen. I have these details, but I don't know how to enter them into the new BIOS. I'm attaching the original dump and the clean BIOS from this site.

I kindly ask if it is possible to remove the password from the original BIOS or update the clean BIOS with the PC serial number and the Mac address.
thank you !!

MEC jTAG ADAPTER SUPPORT MULTI HEADER FOR DIFFERENT PROGRAMMER SUCCESSOR,SVOD,RT809XX,ETC

The MEC JTAG Adapter is designed to save you time by allowing easy and fast access to MEC KBC I/O. It supports multiple headers and is compatible with SUCCESSOR, SVOD,RT809XX and UNIVERSAL programmers.

MEC JTAG Adapter
The MEC JTAG Adapter is built to streamline your work with MEC KBC I/O like , providing quick and convenient access while saving valuable time. It supports multiple header types and is fully compatible with programmers such as SUCCESSOR, SVOD, RT809XX, and more.
This adapter includes all the essential JTAG pins—TMS, TDI, TCLK, RST, GND, and 3.3V—allowing you to power the latest MEC chips directly from your programmer, eliminating the need to connect an external power adapter to the motherboard.
It also features breakout points connected to some resistors places allow you to pull-up or pull-down for key signals like MSDATA, nFWP, and RESET, which are useful in scenarios where enabling or disabling write protection or other features is necessary. These breakouts make it easy to adapt the configuration depending on your specific use case.
The MEC JTAG Adapter comes complete with the required headers for soldering (based on your programmer), a connector, and JTAG wires.


USB-C Line Tracer and Tail Plug Detector – Laptop Dock Tester Tool



This compact USB‑C tester plugs directly into a port to probe every signal line, using the internal ESD protection diodes of connected TYPE-C ICs OR PD CONTROLLER. You can directly check the USB-C Port and all lines connecting to the Type-C chip directly or PD chip , and also know what protocol is activated on this input.
The tester can check all these pins

Power & Configuration
CC1, CC2 (A5, B5): Configuration Channel – determines plug orientation, establishes host/device role, negotiates power level, and signals alternate modes.
Data PINS
D+, D- (A6, A7, B6, B7): USB 2.0 differential pairs – always connected regardless of plug orientation.
TX/RX pairs (A2/A3/A10/A11 and B2/B3/B10/B11): SuperSpeed signals for:
USB 3.1 Gen 1/2
Thunderbolt 3/4
DisplayPort (via Alt Mode)
These lines are flipped depending on plug orientation.
Sideband / Auxiliary
SBU1, SBU2 (A8, B8):
DisplayPort Alt Mode (AUX channel)
Analog audio (e.g., headphone dongles)
USB Debug Accessory Mode (UART)


No HS, SBU, or CC → No CC negotiation; no PD connection .
HS detected, SBU absent → Likely USB‑3.x only.
HS & SBU detected → Indicates support for DP/Thunderbolt or USB‑3.x with SBU-based features.
SBU only → Debug or audio path present, but no USB‑3.x.

MPS PMBUS PASSWORD PROTECTION

MPS PMBUS PASSWORD PROTECTION
1000068222.jpg
Do processor circuit ICs (VRM) really have passwords?
Do you remember the video where I explained how to program modern processor circuit ICs using a PMBUS programmer? I mentioned at the time that in some cases, we would need the schematic, because even though there are many dump files available now, for some models it’s not possible to backup the file from another board because the ic is protected.

This is because some modern processor VRM ICs support a feature called PMBUS Protect. This feature allows the manufacturer to set a password to protect the IC. It provides three levels of protection:
  1. Protection from reading the registers
  2. Protection from writing to the registers
  3. Protection from both reading and writing to the registers
For the first and third types, it's not possible to take a backup from the IC—even if you have a working board with the same model. In this case, you’ll need the schematic to manually build a configuration that suits the processor circuit and its components.

As for the second type, you can still take a backup and write it to a new or used VRM IC later without any issues.

Are there any ways to break this protection? No.

Are there any workarounds to bypass it? No.

Asus Rog G513QR

hello i have an asus rog g513qr ryzen 7 series 5000 that initial not powering on the cpu was damaged , after changing the CPU, bios was corupted and i write another, after we have image on display and windows i attached picture ,bios is damaged with bad serial u have picture (the ic grafic is nvidia 3070) do you think the grafic card fault is from bios or i have to solder the ic or replace the GPU IC?

is there a place to find a parts list and values for a schematic?

Looking for a parts list of mainly capacitors and their values for the schematic ASUS MAXIMUS IX HERO REV.1.0.1A.FZ
