The Dell laptop is not displaying properly after a Windows restart, showing a black screen.
I've set up a fresh desktop and attempted to restore my previous laptop, but encountered the "User Profile Cannot Be Loaded" error. The screen now displays black after powering on. It seems the PC is showing no visuals, only a black display. I've tried several steps—pressing F12/F2 at startup, disconnecting and reconnecting the battery, removing the CMOS connector, using the recovery USB, and even copying files—but nothing resolved the issue. After a restart, I still face the same message. The Dell logo doesn't appear during normal boot, and files from the new PC are copied to the desktop. I'm unsure what action I took next, but it might have been a reset or a power cycle. The system feels unresponsive, and the fan noise is loud. I'm considering BIOS troubleshooting but haven't tried flashing it yet.
Already attempted linking it to an external monitor via HDMI and USB-C to two different displays. Repeatedly pressed all function keys to verify, but no success—thanks for the effort!
This might seem like a humorous concern, but I need to ask. Can you notice the backlight on the screen? If not, try using a flashlight and see if you can detect anything very dim. It sounds like the inverter has failed or isn't starting properly. This is unlikely, but since you've followed the steps you did, it could be worth checking. (Updates won't cause this, but a damaged BIOS or loose ribbon connector might lead to the screen not lighting up, which could look like a black screen. I only bring it up because I've seen some inverters malfunction on Dell systems unexpectedly.)
I attempted to use a torch but didn’t see anything. When I press and hold the D key and power it up, the screen shows a full-color sequence across the entire display. The display cable appears properly seated, so it shouldn’t fail that issue. I’m uncertain if a Windows restore could damage the BIOS, though this seems to be the main clue here. Others have used BIOS programmers that clip onto the chip to fix it. My Dell 9550 should support a BIOS restore, but copying the BIOS file to USB hasn’t succeeded yet—pressing CTRL+ESC doesn’t work with the BIOS on USB, and it flashes three white and three amber/orange colors when another USB is connected. It’s possible I haven’t loaded the right file onto the USB stick yet. I’m not sure if local repair services are equipped to handle this kind of problem. I suspect it might not be a hardware failure, unless the BIOS was corrupted after a Windows restore and caused a profile error during startup.
