Hi guys! We need a bios dump.
Model Legion 9000 PRO 8 (2023)
s/n PF4T63Y1
I downloaded the bios on the official Lenovo website
It is not possible to fill it with a programmer on a flash drive
In the original flash drive, the file weight is 2 MB.
Please help me)Yesterday, 06:36 PM -
Hi, please help me out..
my laptop turn on 3secs then off. No post, fan no spin.
i have checked:
5valw OK
3valw OK
but not 1.8v
signal EN from EC to IC PU1801 is missing (0v).
PR1807 ok. Pin 20 EC = 0V.
Really hope someone can guide me further...
thanks...04-10-2024, 12:42 AM -
I have a card that does post at all, the owner said it does go into windows but it gets stuck on the logo with artifacts, I have no idea if he is lying or not... I tried the card on my pc and it does not post at, no beeps, no bios nothing just all fans turning and nothing else. I tried plugging DVI or hdmi but nothing, I tried unplugging the 8 pin plug from the power supply and it's the same thing.
I just want it to post and get into the bios at least.
Forgive me if I am wrong, but I tested the 3 PCIe 12v power pins on the left(550ohm) and the 4th one from the right 3.3v (400ohm),...Today, 02:42 AM -
I usually tried to find datasheet which contains Maximum ESR value like KME datasheet.
[URL]https://www.westfloridacomponents.com/mm5/graphics/S06/KME250VB10RM10X20LL.pdf[/URL]
As far as I know,Maximum ESR means boundary ESR value for bad capacitor.
But,In many case,there is no ESR value in datasheet like below links.

hi to all
i have this logic board with no back light, image is present.
unknow istory.
on q7707 pin 5 EDP_BKLT_EN found 3.3 v, pin 1 gnd damage, pin 2 BKLT_PLT_RST_L only 0.08v (but is 3.3 on r2088 pin 2)
remove q7707 and find this
any suggestions?

Hello.
Have this Asus RTX2060S dual EVO that dont release core EN because THERM_OVERT* from core is put to low. Anybody knows what triggered this event?

Hello,
So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess
Its a ASUS P5VDZ-MX board.
I would really appreciate some assistance on what the best replacement caps would be for these:

Hello Friends,
Greetings!
I have taken this active subwoofer from Wharfedale for restoration. This is already in a bad shape as far as the connections goes. It has already been worked by local technicians. The most important part that I am looking forward is the schematic diagram, as there is jumper placed and a track has been cut, as if to bypass the actual connection. I am not sure if this is by design or someone has tried something to achieve.
Another thing is the TDA7294 was badly treated with its legs cut and it had a crack too, so I have replaced it...Today, 01:17 AM -
Hy guys, i have this lenovo TB-X605F with charging problem, the tablet is fake charging, i have replaced the charging connector twice, it only draws 0.40 Amps when pluging the cable for the first time then it stops drawing any Amps but the tablet keeps showing the charging image at 0% as long as i keep it connected. I have no voltage at the battery connector with the cable pluged, but i have 5 volts after usb connector on some testing points on the board.04-03-2024, 03:14 AM

Hello,
We have this set here in our shop that is not ginving sign of life besides red light that is blinking one time after pressing the button and nothing more... After detaching the mainboard from the PSU (this set has separate board thank god?! or not...) the backlight comes on. After reattaching nothing besides red light.... Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.

Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...04-13-2024, 10:05 PM
