Power up your ‘Book until the desktop appears on the external display and then close the lid. REPLACING A BATTERY MACBOOK PRO EARLY 2011 13 BLUETOOTHTo used closed lid mode, your ‘Book must be plugged into the AC adapter and connected to an external display and a USB or Bluetooth mouse and keyboard (you might also want to consider external speakers). REPLACING A BATTERY MACBOOK PRO EARLY 2011 13 FULLUnlike early MacBooks, where every USB port could provide 500 mA of power, only one USB port provides full power – the port closer to the front.īattery life is claimed to be 7 hours of wireless productivity.Ĭlosed Lid Mode: All Intel ‘Books support “lid closed” (or clamshell) mode, which leaves the built-in display off and dedicates all video RAM to an external display. Note that the built-in display is only capable of 18-bit color, not the full 24-bit color you might expect. At this time we do not know if they apply to the new Unibody model. If you are replacing your hard drive with another hard drive or an SSD, it might be wise to replace the cable proactively.Įditor’s note: The next two paragraphs are from the profile of the previous version of the MacBook Pro. 128, 256, and 512 GB SSDs are extra cost options.Ĭaution: There is an issue with all 20 pre-Retina 13″ MacBook Pros – the hard drive cables are subject to failure due to the way they are routed. 4 GB of RAM is standard, and it can be upgraded to 16 GB. The new model comes in 2.3 GHz i5 and 2.7 GHz i7 versions. REPLACING A BATTERY MACBOOK PRO EARLY 2011 13 PROThe black keys look sharp with the aluminum enclosure, and the 13″ MacBook Pro only comes with a glossy screen. The 13″ MBP uses the same keyboard as before, complete with backlighting. The entire trackpad functions as the mouse button. It supports 1-, 2-, 3-, and 4-finger gestures. The glass trackpad is the same one found in the previous generation of MacBook Pro models. In testing, the Early 2011 models generally match or outperform the 2010 models. The new models are rated at only 7 hours of battery power, down from 10 for last year’s models, due to changes in the way Apple measures battery life. The 13″ MacBook Pro also takes some steps backward: The Nvidia GeForce 320M graphics give way to integrated Intel HD 3000 graphics, which uses 384 MB of system memory (up from 256 MB in last year’s model). Thunderbolt can be used for video, hard drives, and networking, and adapters let you connect FireWire and USB devices.Īpple has improved AirPort performance by building three WiFi antennas into the Early 2011 MacBook Pros, allowing three channels with 150 Mbps bandwidth for a maximum bandwidth of 450 Mbps. Thunderbolt is 12 times as fast as FireWire 800, over 20 times as fast as USB 2.0, and twice as fast as USB 3.0, which Apple seems in no hurry to adopt. The hot new technology for this generation is Thunderbolt, a 10 Gbps data connection that uses the Mac’s Mini DisplayPort. These dual-core mobile CPUs have a 3-4 MB Level 3 cache shared by both cores and, thanks to Turbo Boost architecture, should be significantly more powerful than the Core 2 Duo processors they replace despite a tiny change in rated CPU speed. The Early 2011 model migrates from the dated Intel Core 2 Duo to Intel’s newer Core i5 and i7 CPUs. a student in classroom environment) Such situations are the reason why we have battery powered MBPs, but if you discharge a battery totally every day, it will need to be replaced well within three years of service.Apple took some big steps forward with the refreshed 13.3″ MacBook Pro. I may not achieve the number of cycles that Apple advertises, but I am confident that I will get at least 5+ years service from them.Ĭertainly there may be situations where an AC connection is not readily available and the cycle count will accumulate quickly and the battery life will be shortened as a consequence. The newer MBP has the original battery and in 19 months of usage is at 96% health. I have a replaceable battery in my old MBP that is about 4 years old and is and is a 91% health. Chronological maximum battery life will be achieved by minimal to moderate battery usage. If you have had the MBP connected to the AC outlet for 4-6 weeks, then do disconnect it and run it with battery power to a 30% - 40% discharge level and the proceed with a charge back up to 100%.Īll batteries deteriorate and discharge over the course of time regardless of whether they are being used or not. If conditions permit, use the AC connection, if not use it under battery power. My intent was not to suggest the the MBP should be connected to the AC outlet 100% of the time.
