Solved! Go to Solution.
You need to enable ptt (platform trust technology) in the bios under security if you want the tpm to work .
regarding the blinking led this might indicate a problem look in this manual expand troubleshooting => system diagnostic lights in what pattern is your led blinking ?
lastly if you want to check if the tpm is working windows key +r and type tpm.msc
