Re: Probook 450g3 bios
Hold down left + right arrow keys and power up, there may be a message then on screen about the flash descriptor being unlocked,then you can make a backup or flash the bios at post #3 with Flash Programming Tool.The flash descriptor will lock again at shutdown/reboot.If it doesn`t work use a bios programmer,desolder or use a sop8 clip .Last edited by SMDFlea; 09-13-2018, 05:28 AM.Comment

Re: Probook 450g3 bios
You can`t backup that part of the bios with universal bios toolkit ,because the flash descriptor part of the bios is locked. Try what i said at post #5 ,if that doesn`t work,try holding down the Win key and l + r buttons while powering up. If nothing works use a bios programmer ,flash the bios at post #3 or #6 .Last edited by SMDFlea; 09-13-2018, 08:52 AM.Comment

Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM -
Hello,ššš
I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.
š§ Model: HP ProBook 11 G2
š¦ Serial Number: 8CG72478MY
š UUID: 6F5ED686-5532-11E7-A2E2-911C6404E011
š BIOS Status: Locked with password
The laptop is no longer under warranty and HP refused to help me.
Iām looking for a custom SMC.bin file.
I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.
Thanks a lot for your help!ššš... -
Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM -
Update bios EFCN58WW to EFCN59WW for solving The Connected AC adapter has a lower wattage than the recommended AC adapter
I have a Lenovo Legion 5 15imh05a device that I bought used online. It came with a 20V 8.5A 170W charger.
The BIOS version is EFCN58WW.
When I turn on the device, it displays the message:
"The Connected AC adapter has a lower wattage than the recommended AC adapter..."
The device rarely charges the battery, and even when it does, it doesn't show that it's charging.

Hello... Where do I start. I have 2 questions/scenarios that might bring this laptop back to life, so here it goes!
I have this laptop (Asus UX52VS) where I was flashing the BIOS to it and it froze during the process. I didn't have a reliable BIOS chip programmer at the time (It was a CH341A USB Programmer from Amazon where it took hours just to get the clamp on the chip and then every time I read, it gave me different results/corruption, and never would pass the verify test as no 2 reads were the same data), so I brought it to a shop. They had it for almost 2 months, but during...
