Bypassing the internal LCD to erase the SSD -- possible?
I have an 840 G5 with a cracked 4K LCD (not cheap to fix!) which will need to sit on the backlog for a bit until I can get a raw 4K screen, used assembly or a locked donor. However, I was able to get it with the SSD (in this market, YAY!) … But I also got their user data since it was very obvious it booted into Windows :-(.
Since the LCD is cracked, I cannot see the BIOS to erase, or check the laptop for evidence of an old OS. Since I'm not 100% sure, I have to worry about “cold storing” someone's data unwittingly. Not exactly fun, but also not the first time.
Is it possible to bypass the internal LCD so I can go into Windows to make sure, and into the BIOS so I can erase the laptop? If not, I will need to remove the SSD, use my fixit contest laptop (this G5 has a SanDisk drive, and I installed a TEAMGROUP SSD in the fixit challenge laptop), boot parted magic and erase it in a NVMe enclosure, and move it back to the laptop.

Hi @nick ,
With an external monitor connected to the laptop, try either starting the laptop with the lid closed (lid switch needs to be operated) or maybe disconnecting the laptop screen from the motherboard and check if that works.
It may depend on what the BIOS is set up to do, if anything regarding the video output
Had the 1st option work on a laptop once, can't remember if Lenovo or not but it didn't on a old Samsung. Heard about the 2nd but it never worked for me
Cheers

@jayeff I tried to plug it into my TV and switch the display to an external but no luck on either the residual OS, or BIOS.
I need to fiddle with it more later, but I want to make it 4K again so I don't want to pinch the cables either.

Did you try disconnecting the LCD from the motherboard and then after booting up toggling the appropriate F keys to external?

@jayeff Not yet. I need to find a way to isolate things as the G5/G6 has very little in the way of tolerances.
Might have to lay it on the side and tuck the cables away... Might be the best way to avoid buying a enclosure as NVMe ones still cost around $20. Not a lot sure but that's a bit much for a thing that's been mature for years.
