Hi there,
You can enable your wireless lan via quick launch button on the strip , when tapped it will show you blue light when disabled it will show you with orange light, if you see that light is still blue but you are unable to find any wireless network in network and sharing center
simply open network and sharing center > go to change adapter settings
right click on wireless network connection and select enable ,
now your wireless should work,
Feel free to contact us if you require more assistance,
Regards,
Bilal

go to the search icon under start. search brightness. it will tell you step by step what to do.
Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.
flashing battery light is normal when the battery is empty ,and the orange led should become steady when you insert charger then it should turn to blue and after the battery is fully charged the led is turned off, i think the problem is that no charging happens check your adapter and the DC input
