We have the laptop for several months and we began to have problem with it last week, LCD do't turn on, and the front light of the laptop flash 2 orange and 7 white ?
If I plug and exrernal monitor on the HDMI port it works. !
1- I did the test by pressing the D key when powering on the laptop and I see the colors
2- I ran the Diag from F12 and received error 2000-0415 validation 119822
3- I updated the bios
4- I updated the video driver
In the system information of the bios it says
Panel type = Unknown Panel
Native resolution = 0 by 0
What can I do, sometimes removing and putting back the battery will cure the problem for 1 boot, next time nothing !?

A technician just change the main board and now the LCD is working pretty well, BUT now the 2 USB port on the right of the laptop aren t working, the one on the left is working correctly.
Just talk to someone at dell and the BIOS and DRIVER are up to date, he told me that I have to reinstall Windows 10 PRO. it is not an OEM version its a retail version !
I'm sceptical that this will cure my problem about those 2 usb ports on the right sides that don't work at all !!!. As you surely know taking a backup and reinstalling all the software on a computer is a cumbersome task and it's really long !!!. We are an entreprise and have no time too loose !
If it's the only solution I'll do it but it MUST be the solution and not because the technician forgot to plug a cable !!!
Please advise !!
