Hi minimemini,
Yes, you can download the drivers and BIOS on the USB flash drive and install them on your system. Before this, I recommend that you check if the device drivers are installed or not. Share the screenshot of the 'Device Manager' with the 'Network Adapters' and 'Other Devices' expanded. Here are the steps:
- Press the key combination 'Windows Logo' key + 'R' key to open 'Run' dialog box.
- Type in 'devmgmt.msc' and click 'OK'.
- The 'Device Manager' windows will appear.
- Click on the sign next to 'Network Adapters' and 'Other Devices' to expand it.
Also, share the 'Hardware Ids' of the device which has a bang in the Device Manager, this will assist me to identify device and its drivers. Here are the steps:
- Open Device Manager.
- Select your device and right click on it.
- Click 'Properties' from the drop down list.
- Click 'Details' and then click 'Device description button' to select 'Hardware Ids'.
- Share the 'Hardware Ids' mentioned under 'Value'.
Note: Before updating BIOS make sure the ac adapter is connected and the battery is charged 10% or above. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.
Please reply if you have any questions.
