I purchased a used PC Lenovo M91p series S4DNVP1 No. Machine Type 0266 (integrated graphics Intel HD graphics 2000).
I formatted and delivered Windows 7 Pro 64 bit.
The problem is that when I ask to put it to sleep is not flashing light and impossible to get sleep, I have to press and hold the on / off button to turn off.
When I again, it says "Windows Resume".
Can you help me please?

Have you updated all the drivers to those on the Lenovo support page for your system? In particular, the Chipset driver and the Graphics driver. I would also update the BIOS to the latest version. You might also run Lenovo System Update to see what other drivers need updating. I have a M91p tower myself, and it has no issues going to and awaking from sleep with Win 7 Pro.

Chipset driver = 11/06/2010 v10.1.0.1008
graphics driver = 05/26/2015 v184.108.40.20629
BIOS = OK (9hjy58usa.exe)
Lenovo System Update = view screenshots (before and after = after installing some software offered):
Thank you for your help.

You can try a registry cleaner, like 'CCleaner', if that fails, then Tweaking.com, Windows repair tool.
