How to enter BIOS on Lenovo T400?
Solution 1
You cannot change BIOS setting while the machine is running. You need to shutdown or restart.
To get into the BIOS setup for the T400 you need to hit the ThinkVantage button, its the small blue bar button at the top of the keyboard. Doing this will interrupt the normal boot sequence and you will be given a menu of options. One of the options is to enter BIOS setup. I believe the key is F1.
Solution 2
During boot, repeatedly tap (spam) F1. However, some generations may change the key, so you could try going up the line if that fails, and onto DEL.
This must be done from being shut down/restarted.

Elitists are oppressive, anti-intellectual, ultra-conservative, and cancerous to the society, environment, and humanity. Please help make Stack Exchange a better place. Expose elite supremacy, elitist brutality, and moderation injustice to https://stackoverflow.com/contact (complicit community managers), in comments, to meta, outside Stack Exchange, and by legal actions. Push back and don't let them normalize their behaviors. Changes always happen from the bottom up. Thank you very much! Just a curious self learner. Almost always upvote replies. Thanks for enlightenment! Meanwhile, Corruption and abuses have been rampantly coming from elitists. Supportive comments have been removed and attacks are kept to control the direction of discourse. Outright vicious comments have been removed only to conceal atrocities. Systematic discrimination has been made into policies. Countless users have been harassed, persecuted, and suffocated. Q&A sites are for everyone to learn and grow, not for elitists to indulge abusive oppression, and cover up for each other. https://softwareengineering.stackexchange.com/posts/419086/revisions https://math.meta.stackexchange.com/q/32539/ (https://i.stack.imgur.com/4knYh.png) and https://math.meta.stackexchange.com/q/32548/ (https://i.stack.imgur.com/9gaZ2.png) https://meta.stackexchange.com/posts/353417/timeline (The moderators defended continuous harassment comments showing no reading and understanding of my post) https://cs.stackexchange.com/posts/125651/timeline (a PLT academic had trouble with the books I am reading and disparaged my self learning posts, and a moderator with long abusive history added more insults.) https://stackoverflow.com/posts/61679659/revisions (homework libels) Much more that have happened.
