[MOD POST] Having trouble with Secure Boot? Check here first

Upvotes

Hello,

The expiration of the 2011 Microsoft KEK CA and the 2011 Microsoft UEFI CA certificates at the end of June 2025 has caused problems with Secure Boot on computers for various folks who have not been able to apply a UEFI (BIOS) firmware update for various reasons.

Because the steps for updating firmware vary not just from manufacturer to manufacturer but between individual models as well, it can be difficult to provide specific assistance and guidance in updating your firmware unless the person helping you has the same hardware.

Below is a list of manufacturers, their Secure Boot certificate update guidance, and links to their support forum(s) or subreddit(s). You may wish to try asking in these places first for expert guidance in updating your firmware, as the people there are going to be a lot more familiar with your device.

NOTE: Please check back periodically for updates to this list.

If you have an update for a manufacturer, please reply with it and we will get it added to the list above.

What to do if no Secure Boot certificate update is available from your manuafacturer

If your manufacturer does not have an update, not all is lost: You can still manually install the 2023 Windows UEFI CA certificate update, by issuing the following two commands from an elevated PowerShell (filename: POWERSHELL.EXE) prompt:

REG.EXE ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Secureboot /v AvailableUpdates /t REG_DWORD /d 0x5944 /f Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"   

Then restart the computer and allow the update to be applied.

NOTE: Two (or more) reboots may be required for installation.

Once completed, you can verify the new certificate has been installed by issuing the following command at an elevated PowerShell prompt:

([System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match 'Windows UEFI CA 2023')

If the certificate has been installed installed, the response back will be "True". You can also use that same command to check if the certificate is already installed.

Regards,

Aryeh Goretsky

Urgent help: Samsung or ipad

Upvotes

Long story short, I wanted a tablet so I can write and study not for entertainment, something which was simple and practical. I went to best buy, and was conflicted with a Samsung or an iPAD. Later went to Apple store, and the store was packed everywhere, a lot of people bought the IPAD, and ultimately I too fell for the hype.

While using the Ipad, I didn't find it smooth at all, it felt like I'm constantly knocking on someone's door while writing, moreover it didn't feel smooth. So we got a screen protector and silicone nib, the writing improved, however the sound while writing is still there, it hasn't improved much, which I (PERSONALLY), don't find comfortable for the price I payed. I got one more week left to exchange the product and go for an Samsung tab FE. Also one drawback is notes app is very limited features, I downloaded a app called noteful, which is free app, so atleast I didn't give my money for good notes and noteability.

Can someone tell me if Samsung would be better for this case in terms of sound and writing while using the notes app. I already have a laptop and don't need anything fancy other than using a simple notes app.

Windows Downloading game gone wrong

Post image
Upvotes

My friend wanted me to download battlefield which needed secure boot so I went into bios. I clicked the reset button to reset everything to default and that then caused a red error about me not being able to use secure boot . It’s a ASUS computer the only way to leave that screen was to. Turn off secure boot but whenever I tried to boot my bios would change the settings back to original. The only troubleshoot I found was to take out the boot and boot absolutely nothing. And that kept my settings from getting sent back to secure boot. Then a few days later my friend wanted me to get on that game again. So I go into bios again. Read something about resetting my keys I go ahead and do that and boot up nothing after resetting my keys. Then immediately afterwards my monitor display does not work at all. (Never getting on mf battlefield bro) computer lights up and runs perfectly fine but no display. Intel i7-13700F. I removed did the screwdriver trick to reset the bios and that did not work so I thought to myself let’s find the battery and see where it is and take it out

Unresolved Laptop not turning on and turns off by itself like 5 minutes after being on

Upvotes

alright so basically my laptop started doing this thing where basically sometimes it won’t turn on and when it does turn on it turns off by itself about 5 minutes later. i took it to get checked out but the place said they couldn’t do anything to fix it because it was some sort of motherboard issue. i was wondering what the next best action would be and whether i should try to repair it or just get a new laptop.

(more in depth description below)

my pc started turning off by itself then coming back on like a month ago. it started with it only happening sometimes like every other day or so, then it started happening like once every few hours, then it just started happening every time i got on. it not being able to turn on also became more common once it started shutting on and off by itself frequently. usually the screen would flicker and afterwards it would send me to the login screen where i would login and it wouldn’t happen again when it first started. now, the screen will flicker like right after launching a game and then i‘m just not able to turn it on for like 10 minutes or it just doesn’t come on at all.

the computer i have is a OMEN HP gaming laptop 16-wd0013dx. it has an i5-13420H, an RTX 4050, 16GB DDR5-5200 RAM, and 512GB Gen4 SSD. im not really sure what the other components could be. i’ve used it for around 3 years. one of my friends said that it could be overheating, which might be the cause since i’ve never cleaned the fans.

if that is the issue, how should i go about fixing it? if it isn’t, what could it be? would it be worth keeping it and trying to repair it or should i just try to buy a new one? these are all the questions i can really come up with, but the main one i want answered is just like whether or not overheating is the issue and what else the issue could be. if you got any questions lmk ill try to answer them

Epson XP-4100 screen died mid-fix, stuck at the last hurdle after a hard week

Thumbnail
gallery
Upvotes

I'm a volunteer admin for a small community org. Spent this week fixing up an Epson XP-4100 that belongs to one of our directors, she used it in her old job before bringing it in for us, leaking cartridge, colour cast, alignment issue, all sorted. Recommended it to her and another director, they trusted me and bought new cartridges.

Then the LCD screen died. No display at all, but the printer's clearly still alive (motors move, it printed fine before). Problem is, cartridge setup needs an on-screen "Completed" confirmation to finish priming, so I'm stuck.

Not gonna lie, feeling a bit responsible tonight even though this isn't really my fault, especially since it's her own printer with some history to it, not just a random donation.

Tried so far: full power cycle, opening/closing the scanner unit, reseated both ribbon cables on the control board, and found the Epson Smart Panel app can actually see ink status without the screen. Tried a firmware update through the app and it's now stuck blinking green saying "printer is operating, wait and try again."

Has anyone gotten through cartridge setup with a dead screen? Any way to force it blind, or is the screen just mandatory for this step? Also open to hearing if a replacement control panel is realistic for a first-timer.

Appreciate any help tonight.

Windows PC Issue: The video card does not the detect audio from HDMI TV. HDMI won't output my PC audio to TV?

Upvotes

On Windows 10, I have 2 video cards. RX 580 and RX 480. I connect the PC to TV via HDMI, on RX 580 I can see both the TV screen & TV audio on playback device. On 480 I can only see the TV screen, when I go sound settings for the playback device the TV's sound does not show is simply not on the list even when "Show Disabled Devices" and "Show Disconnected Devices" are checked. Cannot find it in device manager either, it doesn't show under "Sound, video and game controllers". Drivers are up to date. I also restarted the PC and the TV.

The TV screen is working fine on both. Only the audio doesn't show on the RX 480. But it does show on thet RX 580.

Someone suggested check display settings select "extend these displays". Some home theaters or audio devices are recognized as a second display. Selecting "Show only X" will disable the audio device or show it as disconnected in the Sound panel (control panel > hardware and sound > Sound > playback tab). This did not fix it for me, still no TV sound on the playback list.

All other audio devices including other HDMI devices are recognized and work without issue. I tried reinstalling all my graphics drivers, including the AMD HDMI Audio Drivers, did not work.

Acabé de comprar una PC pre-armada, la verdad soy nuevo en esto de comprar computadoras y es la primera que compro por mi cuenta

Lo que sucede es que al escribir algún texto se omiten carácteres, se duplican o incluso a veces no escribe nada, ya he probado en Linux (Debian) pensando que podría ser un típico error de Windows 11 pero no fue así, me sucedía lo mismo incluso al momento de configurar cosas para la instalación de debian así que no se que podría ser.

Hablé con una IA para tratar de solucionar esto antes de estar seguro de llevar la pc a un profesional y tener que gastar aún mas dinero, pero no me ayudó a solucionar nada luego de mover varias cosas en la BIOS. Me hace mucha ilusión finalmente poder jugar algunos juegos en mi nueva computadora así que espero encontrar aquí a alguien que me pueda ayudar con este problema

My device audio is not consistently playing

Upvotes

I have a laptop called the Dere R16 Air (not a well-known brand). The OS Build is 26200.9278, and it's on Windows 11 Home now.

I started having trouble with the headphone jack or laptop; sound would suddenly stop playing through my earphones, and even my AirPods do not connect to my laptop. It had never happened before, so it was strange. At one point it started working again on its own but then cut out again, so I contacted Microsoft support.

That's when things went downhill. A technician remotely accessed my device to "fix" the issue but ended up installing a different version of Windows without asking, Windows Pro instead of Windows Home, which is what I actually wanted since they made sure choosing to update was not an option. After several failed attempts to correct this, I was escalated to a supervisor, who wiped my computer entirely. They assured me my data was backed up first, but even after the wipe, they still couldn't get Windows Home installed.

Following the reset, my mouse stopped working completely. Rather than fixing it right away, they just asked if I had another mouse I could use. It took two days to get the mouse working again and another two days after that to finally get the correct version of Windows installed all while this was my primary work laptop.

Once things were mostly back, a new problem appeared: my laptop stopped producing any sound, especially using my USB headset, plugged in or not. I contacted support repeatedly, and each time they claimed the issue was resolved—it never was; those were only temporary fixes. Eventually they told me the problem was related to the drivers, said there was nothing more they could do, and directed me to contact the manufacturer instead without explaining what was actually wrong or what I should look for.

Now, audio only works inconsistently: sometimes there's no sound on startup, sometimes it plays for a while and cuts out, and I've noticed it only reliably works while the sound control panel is open. I have to restart the laptop repeatedly just to get audio back temporarily.

Also, during this whole process they had me insert my USB stick into it for them to move data over before doing the reset. I think they did it twice.

I'm not very technical, and after weeks of being given the runaround, I'm hoping someone can help.

Need more info Bios Malfunction

Upvotes

On September 1st, UEFI and Secure Boot were enabled on my PC, and everything was working completely fine.

Yesterday, September 3rd, I turned off my internet connection and unplugged all the cables and peripherals so I could clean the PC. After cleaning, I reconnected everything and turned the PC back on. When Windows started, my administrator account suddenly asked me to create a new PIN. There was also another user account showing on the login screen, but that account was completely locked and I couldn't log into it.

I logged into my administrator account and checked the user settings. That's when I noticed that my BIOS settings had been reset automatically.

Since then, I'm facing a problem with Secure Boot. Whenever I try to enable Secure Boot in the BIOS, the PC boots to a completely black screen and stays there. The PC works normally again as soon as I disable Secure Boot.

The strange part is that Secure Boot/UEFI was working perfectly on September 1st, before the BIOS reset. I haven't intentionally changed any hardware configuration that should cause this issue.

What could have caused the BIOS to reset, and why would enabling Secure Boot now result in a permanent black screen when it was working fine previously?

Unresolved MSI Z370 gaming plus unable to access BIOS

Upvotes

Hey everyone, I have had a very annoying issue with my Z370 gaming plus motherboard. Yes, it is a few years old, so I understand that this might also be caused by some stale transistor or defective parts on the motherboard itself. The main problem is that my motherboard is in Legacy mode. I am trying to turn on both UEFI boot mode and secure boot. As required by some anti-cheat software nowadays.

MSI Z370 Gaming Plus won't let me into BIOS. POST completes so fast the keyboard isn't even initialized in time to catch a keypress. No DEL, no F11, nothing gets through. This is behaving like MSI Fast Boot is enabled, but it is fully disabled. Board has no dedicated physical BIOS-entry button. The integrated GPU on the CPU is not giving any video output for now. Could be because I have at some point it time fully disabled the integrated graphics. Pulling the discrete GPU to access the CMOS battery underneath it kills all video output entirely. And you can imaging how a CMOS reset would look like since the only way to confirm if it is actually reset, is by viewing the screen. Out with the graphics card, reset CMOS, then reinsert the graphics card etc etc etc. Not really a viable option.

  • DEL / F11 key-spamming at every possible timing, including holding the key down continuously from power-on, it just never catches. The USB controller does not start in time to catch the keystrokes. Absolutely a viscous circle, because this is most likely a setting inside BIOS, which I can't even access.
  • CMOS battery pull and JBAT1 jumper reset has absolutely no change to the behavior.
  • PS/2 adapter with a USB keyboard, ruled out early as unlikely to work (although not a true PS/2 signal), and no genuine PS/2-terminated keyboard was available to test properly.
  • Swapping to a second, simpler USB keyboard (no built-in hub), also no change.
  • MSI Fast Boot + GO2BIOS button. I have installed the MSI Fast Boot app for Windows 10 version (not officially listed for Windows 11, works fine to run anyway), tried the GO2BIOS button inside the app. Every time it just boots straight to Windows, flag apparently ignored by firmware or not being set at all.
  • Disabling Windows own Fast Startup with no changes
  • EZ Debug LEDs observed during boot: CPU LED probably to fast to catch, DRAM LED lit for an extended period, then VGA LED lights and stays lit continuously all the way through Windows loading and after login, never clears. Not even once is the BOOT LED lit up.

I am just hoping that anyone here on this forum got a different suggestion than buying a new PC...

Thanks MSI for locking me out of my own BIOS. This is a great design flaw.

I can play all the games except for those games that need access to the TPM chip.

Any suggestions will happily be accepted.
