I think my x201 has BIOS firmware but your X201i may well be UEFI. In which case there are software tools you can use, which we refer to in the Restart Wiki - see https://therestartproject.org/wiki/UEFI_and_GPT
If it's BIOS there should be some way of resetting it - most likely a pair of solder pads on the motherboard that you have to short together. On some laptops I recovered a while back it was a bit tricky but worked in the end. Hopefully, MrGoogle will be able to help you if you pester him hard enough, if not yandex.ru or baidu.cn tend to have less scruples about sharing manufacturers' data.
