Hello, TL;DR: any kernel parameter to stop the closing the LID detection? (because of a hardware problem). Or, is this only controled by hardware? (it even happens before Linux booting up). We have a 1 month old X260 here (currently we are on an Antarctic expedition, so we don't have access to shops). When moving the screen it flickers and goes black: I think that it detects that the LID has been closed even if it hasn't. It happens even before Linux boots. I'll try to disable ACPI on the BIOS but obviously it's some type of falty hardware. We've tried echo LID > /proc/acpi/wakeup as I think it was suggested in some message some time ago without any luck. I've also tried killing acpid. Besides disabling ACPI on the BIOS if possible (and I think that might not work) any other idea of what could be done? (we are now from Cape Town to Hobart, but we only have 2 days there and we would like to not have to buy/replace the laptop). I'm thinking of some Kernel parameter to stop this happening, for example.

This maybe still leaves the firmware option: Is this machine running the latest available BIOS from Lenovo? If upgrading to the latest BIOS is not feasible, i'd rather suggest to replace the machine with another proven good one. -- The linux-thinkpad mailing list home page is at: http://mailman.linux-thinkpad.org/mailman/listinfo/linux-thinkpad |

With the internet that we have here it will be difficult to verify but I'll try to have a look, thanks for the idea. > If upgrading to the latest BIOS is not feasible, i'd rather suggest to > replace the machine with another proven good one. We would also like to do it!
