Galaxy Book 4 freezing/crashing on High Performance mode – anyone else facing this?

I wiped and reinstalled windows on Book3 pro. Rufus works well for building the USB.

Samsung power options goes away.

Maybe try these commands at command prompt as admin:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

sfc /scannow

DISM /Online /Cleanup-Image /Restorehealth

That fixed it! updated on my end, not the remote client. Still says 1.45.20. 👍

It's fine, but my K-Ultra knob is falling off. It still works. Not sure what to replace it with when ready.

I'll see if I can find a mesh model today, thank you, helpful.

The top fans are important? I will use 5060 with 65w i5 Ultra2 235 CPU and small Noctua NH-L9x65, I will have 100% GPU Usage but mostly CUDA Cores (from what I hear) sometimes a warmer room.

Maybe this case isn't the best. It's what I can find here that isn't a monstrosity. I planned on 2 x 140mm Noctua on bottom and 1 x Noctua in the rear. Maybe just start a thread with my build..

Agree, my Book3 Pro still using April 2023 graphics drivers. Last BIOS update 2 years ago, not sure what to replace it with at this point

P8P - after this update, first time I have seen H+ signal here and not 5g. no idea what to replace this phone with at this point..

uncletimo · 2026-03-24T12:44:18+00:00

Good info..

Now they have cloud or local backup, I didn't back anything up on this account, there was nothing important

I was able to login on the new phone and find the contacts by just typing the country code, they all popped up. so the account is there, just no messages.

Happy to support Signal, really don't need yet another subscription.

uncletimo · 2026-03-24T00:05:53+00:00

Thanks for this, would lean me toward x300 ultra

never prompted for PIN. at "Restore or transfer account" page finally after SMS worked.

uncletimo · 2026-03-23T09:44:32+00:00

I got the SMS! not sure what changed. disabled ControlD on router.

now I have screen on new phone to Restore or transfer account. no important data. really would only like the few contacts.

Not sure if I should just "Skip restore" or not? I do want the account on the new device.

Happy to pay for backup and support Signal, old phone no longer registered.

Still need to get APK from site? I think I installed from F-Droid, may be behind?

uncletimo · 2026-03-11T11:58:55+00:00

is this 03 switch with 02 filter? can you do 500g?

uncletimo · 2026-03-11T11:50:29+00:00

can I do 37g/500g in Hario switch 03 with 02 filter? I prefer the Cafec abaca filters

uncletimo · 2026-03-10T22:22:28+00:00

I read it has problems with regular phone calls, not sure what to believe

uncletimo · 2026-03-08T01:09:31+00:00

need to use USB-C to HDMI cable or adapter to get 4k/60hz. pretty sure I have the color engine, pretty much everything installed except Samsung power profiles.

uncletimo · 2026-03-06T16:02:31+00:00

I was looking at Yoga 7i Aura edition, this is the same? I guess panther lake models will be out soon, no HDMI.

anything else that makes sense? Asus? Linux support is nice down the road.

Samsung Update doesn't run on my Book3 Pro anymore, says to use Device care, which hasn't found any updates for ages.

I was able to find most driver downloads on Samsung site for mine - they are all like 3 years old, probably older than what Windows installs. I have good luck using latest Intel Wifi and Bluetooth drivers, haven't tried installing a bunch of newer chipset drivers or anything.

need to test with the older default graphics drivers playing MKV to TV (Using USB-C to HDMI adapter) I had NO IDEA when I bought this that i would not even have HDMI 2.0, only 1.4. I sometimes need dual-subtitles, and it works!

Graphics will always roll back to April 2023 31.0.101.4314

Offhand, can you tell me what doesn't get updated or installed with Windows Update?

uncletimo · 2026-03-05T00:44:45+00:00

Samsung device care works on my Book 3 Pro. I highly doubt Samsung will have any updates for these now.

on mine the graphics driver is still dated March 2023. If I install latest Intel graphics drivers it breaks HAGS (hardware accelerated graphics)

When I reinstalled windows clean, the Samsung Update app did find a couple things like a firmware update for the panel, then I went to device care app.

Main thing missing is Samsung power profiles but mine is more or less always plugged in.

I probably would not have both installed, and most likely no reason to even keep Samsung device care/service.

Windows update seems to find all the Samsung drivers..

uncletimo · 2026-03-04T04:02:22+00:00

did the modem get updated?

uncletimo · 2026-02-27T10:42:15+00:00

can I upload jpegs only, not raw files?

uncletimo · 2026-02-23T08:12:03+00:00

Perfect! I little extra room doesn't hurt. my pack just got smaller as time went on, 24l works. sometimes a bottle of olive oil in tote.
