After hours of research on the Internet, I came across a solution for another Toshiba model which called for updating the BIOS. My BIOS was fairly old (1.4) and the newest version was 5.3 so I figured I had nothing to lose. The BIOS flash came in two versions - CD-ROM DOS and Windows. I typically like to flash BIOS’s in DOS, so I created the DOS boot disk and started the flash with the original battery installed. The flash would not complete because the program detected that my battery was less than 20% charged - kind of ironic since that was the problem I was trying to solve! Undeterred, I decided to try to flash in Windows, hoping that it did not need to detect the battery level. Success - the BIOS was successfully flashed! Once the flash process ended, I swapped in the second replacement battery and started up the laptop - it started and booted to Windows! Once booted, Windows said that the battery was 50% full and it was charging! I shut down the laptop and I am allowing the battery to charge...

I have the same system (Macbook Pro early 2011) and I replaced the original HD with the EVO 860 SSD 500GB. I did replace the cable (heard all of the stories before) and I had no problems making the switch. However, I recently checked the system information and it says that while the SATA port is 6.0 Gb/s, but the negotiated speed is 1.5Gb/s! Since the port and the SSD are rated for 6.0 Gb/s, should I assume that the cable is faulty? I did purchase the newer 2012 cable but not from iFixit. Also, I did not know about putting the tape on the inside of the case until I found this post. Assuming the cable is my issue, I'll do that when I replace it. Is there another possibility for the negotiated speed being lower?
