Looking for a BIOS for HP 255 G8 (HPL51 LA-L021P).
The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
Before junking the board I would try the new BIOS if it does anything.
Thank you!...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

by madan1Hello 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?

by paparazzo79Hi guys.
I ordered used LG 34UM88 monitor which should come with 19V 5.76 A adapter from LG.
I payed for monitor but sadly I got scammed it came with 14V 58W Samsung adapter.
Luckly I did not even tried to turn on monitor, but I think they used the 14V adapter.
Is it possible to use 14V adapter and what already damage could happen?Today, 11:04 AM -
by trepachkaHello, I have the following laptop:
HP Pavilion Aero 13-be0003ca
ProdID: 2L7M8UA#ABL
S/N: 8CG150GPV6
Motherboard information is below:
HP Part# M52826-601

203016-1
It needs BIOS repaired.
I created a flash drive using HP firmware utility and then had it plugged into the computer. I did the standard WinLogo->B key->Power button press. A window appeared and immediately began flashing the bios using the flash drive.
But I don't think it finished all the way. So, now when I attempt...-

by ahoonidHey everyone,
I have a MacBook Air 2017 with a weird problem. The MacBook was totally dead at first and the culprit was the C7430 capacitor which was obvious upon initial inspection as it had a fracture on its surface.
The F7140 fuse was also blown so I changed them both. L7130 due to corrosion was also replaced. Now everything works again. Laptops turns on and everything seems reliable at this point.
The only issue that I'm afraid might bite me in the ass later is the magsafe light as it randomly changes light from orange to green while charging. Other times...04-10-2024, 04:06 PM -
by mikkele86Hello good people of badcaps.
im back with another question
Im trying adjust the current bias accordingly to the manual, but my meter is showing the same value no matter whatever position VR-804a/VR-804b is in.
DC bias is adjusted and is working as intended.
Is my settings on the multimeter wrong ? or should i look for a bad component
note: all transistor are new

by fedeRaiderHello everyone
My TV no longer shows signs of life, but if I unplug the motherboard, the backlight works.
I bought a CH341A USB Programmer, and this is my dump (BN41-02568B):
Could someone help me fix it?...Today, 06:05 AM -
by MDSIHello.
I have an Asus X705UV which no longer starts since the last Windows update. I suspect Windows Update of having tried to update the bios and having corrupted it, because currently, I have the charging indicator when I plug in the charger and I have the power indicator when I press the on/off button but nothing more, not even a fan running.
Could someone check this bios and if it is broken, repair it?
Sorry in advance, google translate is useful but not perfect. 😂
Thank you in advance ! 🙏...-

by orgamishoHello!
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.

by timonix20hello everyone I am looking for a solution for my tv, I think corruption of the eemc,
the TV starts, LG logo, then nothing (rear backlight)
no reaction to rear command or infrared
the usb procedure that I tried on the LG site is a procedure with the screen and the remote control so I can't.
I have a chance with a usb procedure or other if you have .bin
