Lenovo Clear CMOS

Working on old Lenovo desktop I had to clear the CMOS. Here is the strange method:

M7408

1. Turn off the computer and any attached devices, such as printers, monitors, and external drives.
2. Unplug all power cords from electrical outlets, and remove the cover.
3. Locate the Clear CMOS/Recovery jumper on the system board.
4. If necessary, remove any adapters that impede access to the Clear CMOS/Recovery jumper.
5. Move the jumper from the standard position (pins 1 and 2) to pins 2 and 3.
6. Replace any adapters that were removed.
7. Replace the cover.
8. Reconnect the power cords for the computer and monitor to electrical outlets.
9. Restart the computer, leave it on for approximately 10 seconds.
10. Turn off the computer by holding the power switch for approximately 5 seconds.
11. Unplug the power cords from electrical outlets.
12. Remove the cover.
13. If necessary, remove any adapters that impede access to the Clear CMOS/Recovery jumper.
14. Return the Clear CMOS/Recovery jumper to its original position.
15. Replace any adapters that were removed.
16. Replace the cover and reconnect any cables that were disconnected.
17. Turn on the computer. The computer should sound 2 beeps. The time and date should need to be set. If not, the procedure did not work.
18. After resetting the date, time, and saving the settings, exit the System Configuration Utility.

If you need to boot from usb just hit enter on boot to get to the boot selector.

The USB mouse/keyboard takes forever to get recognized but it eventually works.

I like these small Lenovo/Dell units for offices but they can be a problem.
1. There is no room for a second HD for backup. I guess a USB works but not as reliable.
2. If the onboard video goes a dedicated low profile card can be used. Be sure the heat sink is shallow enough to fit.
3. The physically small power supplies can be hard to find and expensive.
