Yes, @imranromi is correct. Has faced this on a couple of HP's. You dont need to do anything. Just flash bios and let the pc restart a total of 31 times and after that . the red line will go away and it will boot normally. You need to add dmi info only after that.Comment

Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
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).

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.

HP EliteDesk 800 G2 MINI/DM (1L PC)
I have 40 of these units. All of which i tried to update bios with HP's utility got bricked. All of them were bios password locked, i used the jumper thing to reset it. Couple updated bios, one of which worked fine for _ONE_ boot. Second is now mixed with rest, i don't know which it is specifically so have not retested it.
All had some MESpilock failed errors on (my) first boot of the unit.
