i coudn't find the installation instruction for running A04 in DOS-Mode
Dell Technician doesn't include any webcam driver or information information for this model Dell inspiron15r SE 7520, u can check the link
no webcam driver or creative webcam central exist
My service tag dosen't include any bios upgrade , without service tag i see all download drivers and bios , but there is no webcam driver or last version of creative webcam central in input category . Dell diagnostic when i press f10 i cannot see any webcam test . so i guess the problem with the bios update i made
How can i reset to the default bios factory , revert or downgrade to the bios that support all drivers i have in my laptop
I am sorry about the situation; Dell does not recommend in downgrading the BIOS. Please provide me the snap shot of the device manager expanding the imaging device. However, you can install the webcam central software using the link below.
In case the issue persists, use the link below to run the Dell PC diagnostics on webcam, click on symptom, select webcam and run the diagnostics.
Let me know about the progress.
i know that downgrading bios not recommended but the new bios A10 did not detect the webcam built installed in my laptop
there is no imagine device at all , here is the image link for my device manage
the webcam central link you provide older than the version already installed in the laptop
here is the image link for my diagnostic screen
the online diagnostic not working at all it stopped in the updating dell system detect point
i wait for more than 2 hours but noting happen
i also tried to unplug the webcam and plug it again but didn't detect at all
