I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.

Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

Couple of Windows 11 machines have come in this week with the same issue. After you login, the taskbar will not appear (or just be a black bar). No access to Start Menu. Task Manager (use CTL+SHIFT+ESC) works, however the Performance stats seem stuck with CPU on 100% for Task Manager itself. Trying to exit Task Manager result in it hanging as well. No issue if you boot into Safe Mode.

First machine, tried many things to no avail (System Restore from last Windows update, rebooting in Diag mode, trying to reinstall Windows Apps via Powershell). In the end, I did an in-place upgrade...

Hello guys,

i got this laptop from a friend to solve a problem.
The Laptop got a black screen. After turning it on, the keyboardlight is on and the fan working sometimes but nothing to see. The LCD is fine.
I did the LCD selfttest.
I think my friend tryed to update the Bios and failed.

I have a TL866 ll Plus and ordered a SOIC8 clamp. I want to flash the Bios on circuit.
I don't know which of the two chips are the bios.

Near the CMOS Battery: MXIC MX25L8006E
Near the CPU: AH1721 259(8)128CSIG E7A026 the 9 can be a 8.

Hi,
I got corrupted bios bin file, which way is correct to repair.
File puts errors on Me Analyzer and cannot open in FIT.

To open in FIT I made:
1. Extract MFS and EFS using MEAnalyzer from other bios file with the same parameters
2. put it in HxD to my file
3. MEAnalyzer shows 1 error after that
4. file opens in FIT

and:

A:
1. extract current dell bios on website
2. put System BIOS with BiosGuard v1.30.0.bin using FIT
3. MEAnalyzer OK no errors
(this version shows only logo at bootup - freezeing)...

I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.

I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.

Does anybody have any insights?

A customer called me up and said that half the screen was like a shadow - presumably the backlight has partially gone. I've never done a repair like this on a monitor, only circuit board based repair on Macbooks etc - is it something that's doable or generally not?

I had this Lenovo Flex 3 1580 worked fine. Suddenly it won't power up. After open it up, I found it can start with lid closed when I plug in the power adapter. (No need to press the power button) If the lid is open, it won't start after plug in the power. After it is powered up, the on-screen keyboard works. But the mouse pad and physical keyboard won't work. The power button won't do anything.

From the symptoms, it looks the keyboard control is not working. The logic of the signal from the lid sensor is reversed. If just one thing is broke, what is it?...

Hello everyone.
I'm troubleshooting a cisco switch, which seems to have an issue with the PSU.
The psu has the following power rails - +12v, -53.5V and +3.3V
When connected to power, the +12 and -53.5 seem to work fine, but the +3.3 starts at ~3v and then goes down to ~0 (I guess this is the cap discharging). This happens both when the cable is connected and not to the switch board.
Any ideas what might be causing this behavior?

My laptop started having a really strange problem....
When I turn it on the fans start working at a crazy rate and with random breaks...
They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.

Hey friends.

I bought a used Microsoft Surface Pro 6 . Good condition, only downside is that the xHCI complient USB Host Controller gives code 10.
I have tried everything that seemed immediately obvious to solve this, like driver updates, roll back OS versions, run all MS's diagnostics tools etc.

The kicker: It works in UEFI just fine.
It works in Grub2, too.
I can even boot off a USB recovery drive thumbstick. However, after it has loaded the image and starts the OSs drivers, it fails.

I bought 2 of these supplies off of Temu , it said they were original for Samsung phones and I bought them cheap so I thought I got a bargain. Looked inside and they are definitely not original. Could you provide any pointers about safety, other characteristics etc. I cannot identify components 5433q 349DJB (what is that?) and it seems it has normal resistor instead of fusible resistor. Is it a fire risk. Lots of questions. Thanks for any time spent on this..

Hey, everybody.I'm asking for your help. Brought this TV in to replace the backlight. After replacing the backlight there are such stripes (see photo).
The glass is not broken, decoders are intact, everything was done very carefully and in antistatic gloves. The experience of disassembling such diagonals is great. I do not understand what is the reason for such stripes that appear a couple seconds after turning on.
Loops rewired, wiped them with alcohol, the connectors are clean. Who by experience can tell me why this happened? Perhaps at the reception did not notice when shining the...

For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
What kind of PSU?
I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?

Currently have a 120/220V switchable SMPS I want to see if I...

I got paid to take this. It had the typical DPS STBY IC bad. Replace it and life was grand....or so I thought. I've never seen this one before; this TV will just magically turns itself on for no particular reason on earth. I did a hard reset on it (twice) clearing all data & settings out.....will still do this. Even removed the batteries from the remote....in the unlikely even there was a stuck key... Still doing it. I did not set up any of the 'smart' functions, I just fed it a source from a HTPC. It doesn't matter what input is selected.....still does it. No rhyme or reason as to frequency....

Today I got a 65" TV from Hass company. It was not showing any picture. I taped the 6 lines of the Tcon FFC cable on the faulty side of the shade and the picture came but the display on the side where I blocked the pins was not showing properly. I checked the volts on the VGH point and -3.5 volts was abnormal, there should be about 28 to 30 volts on this point! There were +30 volts on the VGH point on the Tcon. I put a jumper on the source PCB from the Tcon side and saw, the raster started appearing on the display. I also tried soldering the 6 blocked pins but the picture did not come properly....

Hi, have a HP workstation Z2 Mini 4G for repair with CPU vcore missing.

The resistance at the output of CPU vcore coils, is less than one ohm so I think CPU could be damaged, but no mosfet are damaged.
It mounts an i7 8th gen, and have only i5 7th gen for test, but I think it is not compatible.

Without CPU in the socket there is no short, but there is no vcore voltag, and it emits a beep like no detecting ram.

The controller chip for cpu vcore is a MP2949A, and has no enable voltage at pin 37.

I wonder which circuit generates this enable...

So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...

Hello all,

I have a Lenovo Think Station P700. I bought it second hand in order to use it as a server for home use for testing purposes.
It was running Windows 10 when purchased and I did an update and the BIOS stopped working. I took it to a repair shop and they couldn't find the BIOS for the P700 and told me they put the BIOS from the p500.
But at the moment the BIOS is missing Intel ME. It only shows Intel ME Firmware Version N/A. And current state is: it stuck at Lenovo logo.

HI,

I'm looking to replace the 27MHz crystal on this board as it isn't generating the signal. I thought it would be easy to identify a suitable replacement as there are clear markings on the crystal, but it appears I was wrong as Google gives nothing. Bad photo attached, but it has X27.0000 and 16AP1 on the casing. It appears to be a 3225 package, but looking through suppliers there are lots of different things like capacitance, tolerance, active or passive, etc. that need to be considered. Could anyone help identify a suitable replacement please?

Hello, maybe someone can help me.

The following problem with a Dell Latitude 7400 notebook.

ServiceTag: C5RBL13 Board number: LA-G871P Rev:1.0 (A00)

It doesn't start and when I read the voltage on the USB-C port, it fluctuates around 0.8 watts.

I measure it on the BIOS chip pin 8. It should be 3,3 volts.

There are 3,3 volts but I can only measure 0.2 volts. (+3.3V_SPI)

Is this the possibility that the PCH has a short circuit.
