Issue with Firmware P08ALX for Samsung Galaxy Book 4 Ultra

[AnshuK]

Overview
After updating to firmware PL08ALX on the Galaxy Book 4 Ultra, users have widely reported major issues on forums and third-party sites.

Reported Issues

1.Docking Station: Docks stop working after sleep.

2.GPU: Persistent throttling until reboot; BSODs when switching from Intel to Nvidia GPU after sleep/hibernation.

3.Bluetooth: Bluetooth often fails after sleep.

4.Sleep/Hibernation: Device may not wake or boot, especially if a Windows update is pending; sometimes only battery drain or disconnect helps.

5.BIOS Update: Some users can’t install the update without a factory reset.

Question to Samsung
Why have these PL08ALX firmware issues not been fixed? Users expect a new update, clear communication, and fair warranty support for such a high-end device.

My laptop gpu started throttling bad after I updated to this version. Also lost access to one of the USB ports. Samsung has ignored these for so long now. This should be a red flag for potential buyers. These issues should be fixed before they launch a newer model this year.

The same thing just happened to me when I updated the BIOS.  Did you find a fix for the port loss issue?

I've lost the ability to use my touchpad and and to see my battery % icon in the taskbar after the last Samsung BIOS update.

Samsung's failure to acknowledge these issues is beyond me. Majority of the laptops being sold by samsung are having BIOS related issue. Bios development team at Samsung is not doing a very good job at the moment.

After the update, my computer display has become completely unusable. There's a large orange stripe over a black background, and I can't even access the BIOS to try any fixes. The only way I can see anything is by using an external monitor through HDMI. Does anyone have the previous BIOS version available?

Same problem gpu throttling until crash and then BSOD Nvidia graphics card. How about a fix Samsung?

[AnshuK]

They have not even acknowledged the issues yet - which baffles me!
