As long as you were careful when you removed the battery, chances are that it will work. Since you've already ordered the battery, I wouldn't mess with anything else until you receive and install it.
I think it is a charging LED, though, so if that is the case obviously it won't light up without a battery to charge. It has been long enough that I don't remember if the power adapter LED stayed off or not in that case. It is a wonder it didn't burn his house down. Battery life varies by use and configuration. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 50. That one came to me because the battery had swelled to the point where the touch pad stopped working, requiring an emergency "battery-ectomy". Wireless web testing conducted by Apple in October 2011 using preproduction 2.8GHz dual-core Intel Core i7based 13-inch MacBook Pro units. Seems like it required an 85 watt adapter, and his was outputting less than that. The laptop would boot because the battery still had enough juice to boost it off, but the charger alone wasn't producing enough wattage to boot it standalone. Turns out on that one the power adapter also wasn't up to spec. I haven't worked on a lot of them (not an Apple person myself), but I did look at them on occasion and did have one that wouldn't boot without the battery installed no matter what we tried (and we spent hours trying everything). “We apologize to any customer who has experienced less than optimal performance on their new systems.Yeah, it is sometimes hard to get one running without the battery installed. “Following extensive performance testing under numerous workloads, we’ve identified that there is a missing digital key in the firmware that impacts the thermal management system and could drive clock speeds down” under heavy loads on the new laptops, an Apple spokesperson said. In a statement released today, the company says it’s discovered a bug that’s been slowing down processor speeds when the machine gets hot. There was just one issue, as some early buyers soon found out: In certain scenarios the machines were underperforming due to thermal throttling.Īpple now says it’s aware of the issue and is releasing a software fix to address it. Apple’s line of pro laptops is targeted toward creative professionals who do processor-intensive work on their PCs, and Apple was eager to appeal to them. When Apple revealed its newest MacBook Pro laptops in New York City two weeks ago, it naturally emphasized the computers’ performance capabilities.
