    You have a defective battery. If it’s under warranty, get it replaced. If not, buy a new one. My battery lasts 3.5 to 4 hours, so there’s definitely something wrong with yours and I don’t think it’s software.

    This patch doesn’t fix “dead keys”. It fixes a problem where the keyboard would become unresponsive. “Dead keys” is most likely a hardware problem and cannot be fixed with a patch. Either the keyboard gets replaced under warranty or if out of warranty, the user has to pay to get it replaced.

  3. I was having the dead keyboard problem on my new Macbook. It started about a week after delivery and stopped after about 6 days of it happening on occassion. The mouse still did work. Hasn’t happened in about 2 weeks.

    MacMan, if your battery has less than “300” cycles, Apple will swap it out. Another older Macbook I have had only 45 cycles and the machine would just shut down at about 40%. No warning, just blam, black screen. Took it in to the Apple Store and they swapped it no problem almost 4 months after warranty expiration.
