by StephenCustomer computer came in, did a DFU revive, no luck, gives error, swapped out battery with two known working batteries still no luck. Board gets 20Volts, raises up to 1Amp then restarts, track pad clicks etc. Tried DFU restore, informed the customer that data recovery is most likely not possible since it didn't give us a revive and DFU restore was the next method to save the board, however it looks like not even DFU Restore is working as well. What could be causing this? I am assuming this is the infamous A2141 flaw that has the flawed Data lines that fail? Any suggestions would be great...Today, 10:21 AM

by clearchrisThis crossover was bought new about 12 years ago, and has probably been powered on for at least 3/4 of that time. It also has a recently developed horrible sound on the second channel, sometimes it's a wub-wub-wub, sometimes it's just a hum that comes and goes. It's not noticable if something is playing (it may be gone), but it's quite noticable if there is silence.
Because of age and problems it's due for a recap. I'm also strongly considering putting in sockets to potentially replace the 12 ST TL072 opamps. For such a small device, it's still going to be over 30 screws to take...-

by copeHi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off...Today, 09:40 AM -
by mrralvaroaGood Morning, can someone please help me to fix this bios file?
What happened was the bios got updated and it failed, after it just turns on a black screen and never loads, or if someone has a backup for this bios file that can share with me, that would be awesome, Thanks in advance.

by NagyeszHey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?...Today, 03:05 AM -

by edugimenoHi everyone!
I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
I respected the polarity, positive to cathode of protecting diode
So provided all...04-18-2024, 01:15 PM
