I reached the point when I am unable to work with windows 8.1 on this computer: USB ports fail, computer freeze, very slow stand-up. However, it is impossible to install Windows 7 as a fresh install. It hangs with the Starting Windows screen, although I downgraded all the drivers to windows 7, and upgraded the BIOS. Toshiba does not respond to my help request, even though the laptop is registered on their support page.
I purchased a highly customized version of the Toshiba P70 laptop in Oct 2013. One of the options I included was the Intel Dual Band AC-7260 wi-fi card. During the two months I have had the computer, I have experienced constant wi fi drops. It happens at home, at work, at restaurants and just about everywhere I have used it. In trouble shooting the problem, I went to the Intel web site and discovered that the Intel Dual Band AC-7260 wi-fi adapter is not compatible with Windows 8. This quote is from the Intel web site:The data reordering issue causes intermittent WiFi connection loss and application hangs on Windows 8* platforms. I called Intel and they indicated that they have a partial fix, but it only works about half of the time. Intel strongly recommend that I replace the wi fi card...but Toshiba is refusing to help. They will only replace the card with another identical card, which will still be incompatible. I have already wasted 5 hours on the phone trying to resolve this issue with no luck. So, Toshiba sold me a computer with a wireless card that is incompatible with the operating system....and they will not give me my money back or fix the problem. The computer is useless as a business tool. Buyer beware.
