So while browsing a post on a tech forum for another issue, I clicked a link and my computer started beeping and an alert popped up on the web page. I couldn't close the webpage so I decided to restart- bad idea!
Now my computer shows the dell logo and then immediately (no POST) shows a blank blue screen. And a few minutes later, it shuts down.
My computer is a Dell XPS running Windows 10. I tried an ePSA troubleshooting diagnostic and all my internals seem fine.
If now it is not possible to boot even in BIOS menu, I would recommend you to disconnect the power cable and battery and hold the power button for 30 seconds. Reconnect power cable and try to boot again. Additionally, check the laptop’s manual for any guidance how to reset BIOS to its default settings. Usually this can be done by removing the CMOS battery for a few seconds, but when it comes to laptops the battery is usually out of reach. If the PC is under warranty, I would recommend you to contact the seller.
