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.

HP Envy x360: Screen not turning on after replacement

Mon, 04 May 2026 13:06:48 -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?

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!

HP Pavilion x360 14-ek0033dk: My laptop not power on. Only ON light is glowing coming

Sun, 03 May 2026 12:37:04 -0700

My laptop when i switch On. Only ON light is coming. Very rarely Windows stats and can work. If I keep the lid open and use that time the laptop works. But I shut down the laptop it will not work.

If the lid closed when rarely open windows , it was seated as "sleep" we can use after any time. But if I switches OFF. Then after switching ON it will not work / loading the window.

When i switches ON only monitor lights up . And no caps key lights. Switches on light also lights.

help me how to clear the issue.

Acer Aspire V Nitro VN7-591G Disassembly: ACER Aspire Vn7-591G - where is the SSD?

Sun, 03 May 2026 11:39:12 -0700

My sister has an Acer VN7-591G laptop that won't boot (black screen, no output to HDMI)

She wants me to get the photos off her hard drive.

No problem I thought. I've popped out the HDD, but it is empty other than an old "iMovie Backup" directory.

Looking at the specs, it is supposed to be a dual HDD/SDD, so I assumed that the Windows installation and all her photos are on the SDD

However, there is no SSD in the machine! According to this guide:

https://www.myfixguide.com/manual/acer-a...

there should be an M.2 SSD on the bottom left of the motherboard. But that slot is EMPTY!!

How, if there is nothing but a few random files on the HDD was this machine ever booting? Is there somewhere else that Acer hide the SDD? I certainly can'y see anything...

It is so strange - it looks like it had an SSD (As the hard drive is empty), but its not there! What am I missing?!?

TIA
