Processor power consumption in S1 standby may be greater than power consumption in idle S0 state. This is due to the C1E feature in the newer 0F41 Intel processors. It reduces the power consumption when in S0 state but does not affect S1 state.

Any of the following ThinkCentre systems running Microsoft Windows XP or Windows 2000 as the operating system and configured with a Pentium 4 processor supporting C1E mode:

• ThinkCentre A51 (type 8122, 8123, 8124, 8129, 8131, 8132, 8133, 8134, 8135, 8136, 8137, 8138, 9212)
• ThinkCentre A52 (type 8153, 8154, 8155, 8156, 8157, 8158, 8159, 8160, 8161, 8162, 8163, 8164, 8165, 8166, 8167, 8168, 8169, 8170)
• ThinkCentre M52 (type 8099, 8110, 8111, 8112, 8113, 8114, 8115, 8116, 8211, 8212, 8213, 8214, 8215, 9210, 9211)
