Enabling RC6 support in the i915 driver saves about 3 W, while the pm-utils changes currently being tested shave off another 1 W. * This has improved during precise development. Now in the 7 W range so long as RC6 is enabled. * Display artifacts are seen from time to time. * Has improved during precise development, I'm no longer noticing these. * Wireless cannot use DFS frequencies in 5 GHz band * Workaround: Set regulatory domain manually == MacBook Pro 8,2, ATI graphics (CID 201112-10200) == === Hardware Configuration === * '''CPU''': Intel Core i7-2675QM (SandyBridge) @ 2.20GHz, 4 cores x 2 threads * '''Memory''': 4 GB * '''Storage''': Hitachi HTS54505 500 GB HDD * '''Optical''': MATSHITA DVD-R UJ-8A8 * '''Graphics''': ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] [1002:6741] * '''Audio''': Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] * '''LAN''': Broadcom Corporation NeXtreme BCM57765 Gigabit Ethernet PCIe [1434:16b4] * '''WLAN''': Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] * '''SD Host Controller''': Broadcom Corporation NeXtreme BCM57765 Memory Card Reader [14e4:16bc] * '''Firewire''': Agere Systems FW643 PCI Express1394b Controller [11c1:5901] === Known Issues === * Sometimes hangs trying to suspend (s3). This is being caused by the radeon driver. * Now fixed in precise. * Screen flickers after LVDS panel is turned off and back on. Being tracked on https://bugs.freedesktop.org/show_bug.cgi?id=44955. * Now fixed in precise. * When machine is resumed from S3 without AC power applied, the wireless becomes unable to associate with any networks. Reloading b43 fixes the issue. * 802.11n is not yet supported with this wireless chipset (b43 lacking 802.11n support with HT phy). * Power draw is excessive when using the radeon driver, ~30 W on an idle desktop. Drops to ~15 W with fglrx. According to upstream devs the power management support in radeon just isn't on par with fglrx at this point. * Cannot adjust display brightness. Support is available using various versions of gmux support available online. * Gain on internal microphone is extremely low, even when set to max volume using sound settings. == MacBook Pro 8,2, Intel graphics (CID 201112-10199) == === Hardware Configuration === * '''CPU''': Intel Core i7-2675QM (SandyBridge) @ 2.20GHz, 4 cores x 2 threads * '''Memory''': 4 GB * '''Storage''': TOSHIBA MK7559GS 750 GB HDD * '''Optical''': MATSHITA DVD-R UJ-8A8 * '''Graphics''': Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) * '''Audio''': Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] * '''LAN''': Broadcom Corporation NeXtreme BCM57765 Gigabit Ethernet PCIe [1434:16b4] * '''WLAN''': Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] * '''SD Host Controller''': Broadcom Corporation NeXtreme BCM57765 Memory Card Reader [14e4:16bc] * '''Firewire''': Agere Systems FW643 PCI Express1394b Controller [11c1:5901] === Known Issues === * Wireless does not work well.
