Inspiron 7520 doesn't boot to external monitor after bios upgrade

Hi

After updating my Bios From A5 0 to A9 I can no longer restart my laptop without opening the lid & pushing the power switch twice. It worked perfectly before the Bios update. Please Help!!

Thank You

Hi Trav135,

Do you normally shut down the system or put it to hibernate/sleep? Also update chipset and video driver using the link below.

http://dell.to/Yefr3p     Chipset driver

http://dell.to/12LqSI5   Intel video driver

http://dell.to/Z0iYX1     AMD video driver

Please update the driver in the exact order and restart the computer after each update.

Let us know about the progress.

Thanks and regards,

Hi Senthil - thank you for the quick response

I usually put the system to "sleep" and wake it up with a external USB keyboard - this still works fine. The problem is if I need to restart the system (ie after software installation) then the system stops and I have to open the lid on the laptop push the power button once to close down the system then once to start - as soon as I reach the windows startup screen I can shut the laptop & all is fine

I will try the updates you suggested - all was fine though until I updated the bios

I will let you know how I go :-)

Regards

Trav

Hi

I've updated the drivers as per your instructions - still the same - cannot reboot with external monitor connected & lid closed

Re: Inspiron 7520 doesn't boot to external monitor after bios upgrade

Hi,

I've got the same laptop and I'm running into so many problems. I installed BIOS update A09 a week and a half ago. Shall I update the above drivers using the links provided?

I'm in the UK (not sure if that makes any difference).

Hi Trav135,

I am sorry for the delayed response, Please check if the power option settings are similar to the image which is mentioned below.

Let us know the mode of connection which you are using for the monitor like VGA or HDMI?

Also let us know what kind of light activity you notice on the system when you re-start.

Re: Inspiron 7520 doesn't boot to external monitor after bios upgrade

Hi Senthil,

I have updated my laptop with the drivers mentioned, and although they helped to an extent (takes 10 minutes with variation of 2-7 beeps instead of 20 minutes and repeated 5-7 beeps.

I still get error codes 1a and 3b, which flash up. I honestly think it's a faulty motherboard. I'm worried that one day, I'll wake up, switch the laptop on, and it won't boot at all.
