Hi everybody I need some help. I have two sticks of ddr5 and one of them spd got corrupted. The stick of ram only works if installed as second will never boot alone. By checking it by thaiphoon burner it says CRC error detected but motherboard's spd reader can reead it's info. I tried to reflash spd from second working stick by using OC Tool but it says: some blocks are write protected and will not flash it.
Please help me find a tool to flash the spd back to it.
Thanks!

Intel NUC 7i7 - attaching m.2 drive causes no picture output
Hello,
I am getting a bit desperate with this one and would appreciate any help.
I came across a NUC 7i7 that initially had a short on the USB header "rail" (one of the decoupling capacitors). But, besides that, it displays a weird behaviour - if I don't attach anything to the m.2 slot it works great (boots into windows, etc.). However once I plug in an m.2 drive the computer won't display anything on the screen.
There's no picture, but the computer is still working (I can turn on/off numlock, etc.). This behaviour remains the same even if I disable...

A2289 won't power on
Hi,
I bought a faulty A2289 for myself.
The USB-C meter was stuck on 5V.
After remove the board the U3100 was corroded and also around but quite light.
So I clean the U3100 and see R2834 in bad condition and its value was not good.
I replace it and not the USB-C meter shows 20V, the fan is spinning, CPU is hot but nothing else no picture.
The USB-C meters shows a very low current with all connected. It starts at 20v few mA and then stays at 20v 100mA.
How mush current the board is supposed to take without nothing...

Attempting Data Recovery WD20EARS series HDD Reads as 0 byte drive.
I was wondering if there is a knowledge base on troubleshooting HDD failures and when it might be viable to try certain repair/recovery techniques.
I recently got a WD20EARS 2TB Drive from a customer in hopes of retrieving data. The drive reads as zero size, I can't hear any head activity but it does appear the platter is spinning I can feel some gyroscopic action picking up the drive.
As a shot it the dark I bought a donor board and swapped the rom chip. Same issue zero byte drive.
I'm assuming that the armature is no longer functional internally so no data can...

Chinese windows tablet bios lock removal
Long story short: bought a 8” generic windows tablet (based on Atom x5-z8350, bios chip model is Gigadevice 25LQ64CVIG, uefi vendor is AMI Aptio) for some experiments, and it came with bios lock! I dont have any decent 1.8v programmers at hand nor do i have knowledge in modding uefi firmware, so decided to play safe: dumped the bios with AFU utility, which i attach here. I am hoping to get it unlocked. Also included hwinfo screenshots with general information, the board itself looks generic without any markings.

A1706 short PP3V3_S5
Hi friends,
I have a macbook pro A1706 820-00923-A that won't start no signs of life, no liquid, checking the voltages I found PP3V3_S5 was shorted, I removed all the processor coils, but when I 'injects a voltage it is the processor which reacts, can you confirm to me that this is definitely coming from there please?
I have 20V on the usb-c connector, and 13v stable on ppbus_g3h.
I saw that a track had burned out on PPVIN_2V7NAND_LB after resistor R9350
I injected voltage on L7660 pin 1 in short but only the processor reacts

Bios that supports Title letters in password on disk
Hi everyone. I used Acer Travelmate 6292 with BIOS v.13112, Santa Rosa 1436 (VGA Bios version). This BIOS supported title letters for creating password on HDD.
A week ago an element on textolite burnt and I cant turn on laptop.
I thought that title letters support different types of BIOS.
I tried my new laptop lenovo and my friends old Acer and to regret nor mine nor his laptop doesnt support title letters in
Standart HDD 2,5 inches.
How can this problem be resolved?
Lots of BIOS versions of different types of laptops support title letters in password?...

Would need some help with this mini PC, the issue is - after turning on, PC starts, but there is no picture on the screen, no reaction on LED in external keyboard. Tested with another known good RAM. All voltages are present. Looks like BIOS issue to me, right?

Need help finding what IC this is!
I'm working on a board that is used to control the charging for a lithium battery. I've tracked the source of the fault to this IC, I believe it's the charging controller but I can't find a datasheet to confirm that. Does anyone know what IC this is?
The text reads:
OAS
TI 24I
AV7V
I struggled to tell if the 'I''s are 1's or just 'I''s. See image attached. Any help would be greatly appreciated!

How do I flash bios to an Alienware M16 R1 AMD edition?
I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...

Studio Electronics ATC-1 disturbing signal around 8Khz
Hi,
I have this synthesizer Studio electronics ATC-1 form 1996. It works well but there is some disturbing kind of sine (i guess) sound at around 8 Khz. For now I filter it out with an eq and can perfectly use the synthesizer. But I wonder what this could be. Any idea on what to verify (I only have a multimeter) or what to look at or possibly replace to understand where this disturbing sound is coming from an how to maybe fix it? The photos added are the synth inside and two print screens (synth switch on and synth switched off) of a software spectrum analyzer showing the two loudest...5 Photos

Centronics ZAT502HD ATSC Set Top Box
I watch some basic TV using an ATSC tuner set top box which outputs HDMI to my LCD TV. The brand is Centronics, which seems like a fairly low cost (ie cheaply made) product. The UI is a bit crude looking compared to what I've seen on TVs that have the ATSC tuner built in (but it works!). Anyway, the set top box has always had an odd behaviour, which is that turning the device on using the remote would sometimes not "stick", that is, it would turn on momentarily and then immediately turn off. It didn't do this all the time, but it did this randomly since I've had it, which is 2009. Recently...

MBP 2019 16" (A2141) LCD went out.
Hey Friends,
I have an MBP 2019 16" (A2141), i9/64Gb/1Tb, and recently the LCD went out. Not flexgate or Dustgate. Backlight is on and works, the board still works and posts to an external monitor. Not a software issue, absolutely nothing shows up onscreen except for backlight glow. opened the bottom cover and resistor L8504, a 120 ohm resistor (I believe) is fried, and fell off the mobo with a gentle touch. after it fell off, same problem with zero change observed which is why I think it is the issue. That resistor, acc to the 820-01700 motherboard schematic, goes straight to pin 46...
