내 레노버 노트북 ThinkBook 16 G4+ ARA의 바이오스 칩이 죽어서 바이오스 칩을 새로 주문하고 배송받았어. 이제 바이오스 파일을 구해서 ch341a로 플래시해야되는거로 일고있는데 내 모델의 바이오스 파일을 레노버 공식 사이트에서 찾아서 압축풀고 .fd파일를 구했는데 내 바이오스 용량보다 크고 시작이 MZ..으로 시작해 UEFITOOL로도 열어봤는데 다른 노트북 바이오스들은 잘 되는데 내 바이오스 파일만 올바르지 않은 구조라고 떠.

HP Envy x360: Screen not turning on after replacement

Mon, 04 May 2026 18:13:50 -0700

So, my hinge broke off of the back cover on my HP envy x360 15ey0002nc about two months ago, I tried to open the laptop up and in the process broke the screen, which already had the glass broken from closing the laptop with the broken hinge.

After waiting for all the parts to be shipped I finally got to replacing the back cover and the screen, I transferred all the cables and components to the new back cover, but when I connected the screen and power the laptop back on the new screen wouldn’t turn on. When I tried putting the old screen back just to see if it lights up it also didn’t work.

An important thing to note is that during the replacement of the screen this small (same size as the one in the screen bezel) magnet just appeared out of nowhere and I don’t know where it came from. Anyway I trued restarting the laptop, resetting the BIOS, even updating the graphics drivers and nothing seems to help. I also wanna mention that with an external monitor the laptop works fine and everything else is working.

i came across a post on Reddit talking about the hall sensor cutoff switch for the screen, that’s normally used to detect when the laptop is closed to turn of the screen, and that it might be stuck in the off position and that’s why the screen isn’t working. However I haven’t been able to locate the hall sensor, even though I know where the magnet in the screen bezel is. Would anytime be able to help me fix this issue?

Lenovo Legion: Lenovo Legion Pro5 16IRX9, no power after ECreplacement, PU6201 damage

Mon, 04 May 2026 17:43:13 -0700

Hello,

I hope you are doing well. I found a previous answer saying PU6201 is an RT6585CGQW Richtek voltage regulator, and it was one of the clearest references I found online. I am dealing with a similar Lenovo Legion motherboard issue and would appreciate any advice.

My laptop is a Lenovo Legion Pro 5 16IRX9, Type 83DF.

The laptop originally stopped working and had no power. During the repair process, the EC / Super I/O chip was identified as faulty.

EC chip: ITE IT5570E

I replaced the EC chip, but after that, another issue appeared. The chip at location PU6201 now seems damaged. Here is the image

From what I found online, PU6201 might be:

RT6585CGQW
Richtek voltage regulator

I wanted to ask if this is the correct replacement part for PU6201 on my board, or if this Lenovo Legion Pro 5 motherboard uses a different version.

I would also appreciate advice on what checks I should do before replacing PU6201. I do not have much experience with motherboard repairs, so any guidance would help a lot.

Thank you very much for your time.

My HP ProBook got wet with water and now it won’t turn on. At one point, after cleaning it and letting it dry, it turned on, but the fan wasn’t spinning. Then I checked it again, and after that it stopped turning on completely. Now there are no indicator lights at all, except the one near the charging port

ASUS TUF Dash F15: Display won't turn on, battery indicator flashes white.

Sun, 03 May 2026 13:42:36 -0700

Context:
I left my laptop on overnight, and it shut itself down from low battery by the time I woke up. Perfectly normal, I've done that multiple times. Laptop worked perfectly fine before this problem occured.
-------------------------
To my dismay, when I plugged the charger in and turned the laptop back on, I was greeted with a black screen, followed by the battery indicator light blinking white 3 times, in approx 5second intervals.
I thought it had been the battery not charging, but when I turned the laptop off, the battery indicator glowed orange, indicating that it was in fact charging like normal.

I've disconnected the battery by opening the laptop up, held the power button for 30 seconds, thinking the problem was static in the components, but that too did nothing.
I did notice a bit later however, that all the fans and internal components sounded like they were running.
Finally, I tried hooking the laptop up to an external display. As I suspected, it worked.
No signs of the original laptop display being detected, though. I was wondering if I could get the original laptop display working again.

I'd appreciate if anybody could diagnose the problem, and help me with a fix, if any. Cheers!
