Recently, I manually shut down the computer while running SimCity 4 Deluxe. Upon booting, the computer froze up at "toshiba_acpi Toshiba Extras." I then added "acpi=off" into grub.cfg to allow me to boot into Linux Mint. Battery information like power and temperature were not shown on the battery meter. As the only option I could think of, I blacklisted the line "toshiba_acpi." After that, I noticed that whatever I inserted into the usb ports could not be detected in Mint or Bios. I completely dismantled the computer to replug the USB connection to the motherboard, but that didn't help. I now think that the manual shutdown resulted in a power surge, causing the usb ports to fail, which made booting freeze up at "toshiba_acpi." How can I fix it, I've tried everything?

If you need more information, just ask; I spent 7 hours working on this =(. I have a Toshiba Satellite L500D running Linux Mint 13. Motherboard, and all other hardware are FINE, I completely disassembled the computer to replug the connections...

(update: When I connect an optical mouse, the red laser appears; I'm skeptical it was a power surge.)

All help is appreciated, PLMA

I noticed this problem this morning when I was trying to run Ysflight with a usb joystick, mouse, and keyboard. –  Please let me ask Apr 21 '13 at 21:44
    
Try booting with the driver enabled but the USB port header disconnected. If it was a power surge this will confirm the problem is a hardware problem. –  Ramhound Apr 22 '13 at 11:25
    
That's a bit of good news, the rest of my hardware works PERFECTLY fine, actually better than before. I don't think a missing driver is the cause, then usb devices would show up in the BIOS at least. –  Please let me ask Apr 22 '13 at 21:23
    
USB port header, what is that? –  Please let me ask Apr 22 '13 at 22:28
    
The USB header is located on the motherboard. Its what makes the USB Ports work. I assumed you what it was since you already reconnected the cable. –  Ramhound Apr 23 '13 at 10:49

If the problem was caused by a power surge, it is possible that it caused damage to your hardware. If it is the case, these is not much you can do from the software side. Try to see if the OS detects all of your hardware, if some pieces fail to be recognized you could try to install it in another machine to make sure that it is damaged, and, it it is the case, substitute it with new ones.

Drivers are fine, PC was recently updated anyway. In the BIOS, no usb devices found. –  Please let me ask Apr 22 '13 at 21:24
    
I wasn't talking about drivers, if an electrical surge has occured, it may have caused physical damage to the hardware, not some malfunction by the software side. If the USB post was burnt, you would need to substitute it. –  Sekhemty Apr 22 '13 at 21:54
    
Sorry, that was a response Ramhound's comment. –  Please let me ask Apr 22 '13 at 22:24
    
Yes, the rest of the hardware is detected. –  Please let me ask Apr 22 '13 at 22:26
    
I believe the only option now is to repair the hardware since I highly doubt it's software issue; I'm just afraid that if I but new hardware it might not work. What do you suggest I do: send the computer to a technician, or save money by buying new USB ports? please reply ASAP, PLMA –  Please let me ask Apr 24 '13 at 11:32

Well, I was left to only one choice; I replaced the motherboard ($90). The usb ports, fan, and speakers work better now.
