2019 MacBook Pro is not waking up from sleep

I have a 2019 MBP running Tahoe 26.2 with a 2.3 GHz 8-Core Intel Core i9 processor. I have started having issues waking the MBP from sleep. I open it, and the screen stays black. I have to fiddle with the keys, open and close it, or remove and insert the power cord to get it to wake. Any suggestions?

Thank you. I tried this, although my MBP didn't act as the directions indicated (it started up without my having to press the start key). I realize that I am hearing the "startup" sound while I am using the laptop, which is weird. I will see how it works now.

from the reference

Step 2: Reset the SMC (if issue persists)

3 Keep holding all three keys for 7 seconds, then press and hold the power

button as well. If your Mac is on, it will turn off as you hold the keys.

you continue holding all these keys down....when you press the power button as well

OK, I got it to work! I didn't realize that I have an Apple T2 security chip, but when I was able to get the directions specific to that,

the MBP is working normally. Thank you.

Good computing Fantine ! That is a great report, I appreciate your feedback .
