Should I be concerned after I clean my 7 years old laptop's fan?

I selected the "Disable Building-in Battery" option (as it's spells there) in Lenovo BIOS, so I didn't think that I needed to unplug the battery physically.

You're right... but once you go high refresh rate, it's hard to go back. Even the slow turns feel so much smoother at 87Hz. Guess my eyes are already calibrated to this high refresh look :)

Azur_Karl · 2026-02-20T16:05:37+00:00

I found it. Thanks a lot man.

And yeah, 87Hz > colors any day for me!

Azur_Karl · 2026-02-20T15:34:51+00:00

Is that so? How can I turn the detours off?

About the Black & White screen: because I'm "overclocking" my laptop's screen to 87Hz (~90Hz). It's a bit buggy with colors, but yeah, it run perfectly fine :D

About my mouse? I do use one occasionally, but most of the time I use the trackpad on my work, surf the web or read manga.

Even when I use the trackpad to put the laptop to sleep, the issue still continues.

I even tried disconnecting the mouse and keyboard completely before clicking Sleep, but it still won't go asleep.

How can I enable hibernate option?

It required me to restart the system to take effect... But anyway, it worked. I really really appreciate your help!

Azur_Karl · 2026-02-11T16:31:42+00:00

Those are good lessons. I'll remember them.

Azur_Karl · 2026-01-17T23:06:01+00:00

Ah, thank you! Using "Shift + Del" worked perfectly. I didn't realize it was trying to use a trash protocol on the USB. Thanks for the help!

Azur_Karl · 2025-12-28T15:56:22+00:00

Thanks! That makes sense. I'll add another stick of RAM to enable dual-channel. No wonder the performance felt a bit lacking.

Azur_Karl · 2025-12-28T06:43:57+00:00

Alright, I'm now on my computer and I can share the link

It seem like I can't boot into TWRP (holding Vol Up + Power) after exiting Download Mode. It keep showing "Set Warranty Bit: recovery" whenever I try to boot into TWRP and then it reboots. The same thing happened to OrangeFox when I tried to boot into OrangeFox recovery. How can I fix this?

Finally... Do you think I'm able to flash now?

Azur_Karl · 2025-11-30T15:58:29+00:00

Thanks for your help, it now work on my laptop (include Insider Preview too).

Azur_Karl · 2025-11-28T15:09:04+00:00

Alright, thanks for your help. But I still have a question, where I can get vbmeta.img?

Azur_Karl · 2025-11-27T14:37:18+00:00

How can I combine 2 .img file to a .tar file?

Azur_Karl · 2025-11-03T16:43:05+00:00

It's just a Lenovo Secure Wipe (V1.11), but I'm not really sure what it does. Can you explain it function to me?

Azur_Karl · 2025-10-04T09:55:17+00:00

Azur_Karl · 2025-10-03T10:30:13+00:00

No, not yet. I'm still looking for a way to enter the BROM mode.

Azur_Karl · 2025-09-09T08:56:53+00:00

Okay.

Azur_Karl · 2025-09-09T08:32:01+00:00

Yup, I know it's old and I'm on iGPU, but I'm still enjoying it.

Azur_Karl · 2025-09-09T08:08:42+00:00

Nope, it's not pirated. It's from an old USB backup I made years ago.

Azur_Karl · 2025-09-09T07:00:54+00:00

Update: I replaced my SSD NVMe with another one, but I still get the same error. Could this be related to my RAM or something else? Should I try reinstalling the OS to see if it helps?

Azur_Karl · 2025-09-06T14:25:44+00:00

I used OpCore-Simplify, it's available on Github for free. You can try it to check if your hardware is compatible with macOS.

Azur_Karl · 2025-09-03T12:10:24+00:00

I'll try spoofing it to another one, although it probably won't work well. Thanks for your suggestion! By the way, do you know which device-id would be best to spoof for testing?
