There is a small cable that leads from the power strip to the motherboard. If that came unplugged, the motherboard will not get the signal from the power button. Pull the keyboard and power strip back off and check for connection at the power strip and motherboard.

If you're positive you didn't unplug or rip anything while installing new USB ports, trying checking/updating or rolling back the drivers for the touch pad. Installing new USB ports could have mis-configured something and disabled or modified your drivers for the touch pad.
Directly above the touch pad is a button (sometimes has a light around it red off, blue on). This button turns the touch pad off and on. Once you press the button, give the laptop a second or two to recognize the device and then try it. If this does not work look under device manager, to see if there is anything next to your mouse devices. If there is an explation point or anything you probably need to reload the drivers. If there is a red X, this will normally indicate the touch pad has been disconnected physically. If you are somewhat hardware savy, remove the keyboard and check/reconnect the touch pad.
Hope this helps.
p.s. no I did not give instructions on how to take apart the computer or remove the keyboard. If you do not know how to do this, I would not recomend that you do.
You will have to clean the keyboard touch pads. its a pain full job because one has to remove at least 50 screws before one gets access to the key pads.
Remove the back cover and make a note of what screws goes ware.Then remove the screws that hold a long circuit board over the keyboard ( lots of small screws ) . Invert this board and clean the black carbon tracks as well as the rubber key pads with solutions like WD40. Install it back in the reverse order making sure you put all the right screws in the right place. Should work fine after that until dust again gets in between.
I had the same problem after my fat cat sat on my keyboard. This is how I fixed it. At the top of the keyboard there is a F9 key. If you look closely at this key, it also has two pictures of the mouse pad. This key is a toggle that turns the mouse pad on and off. Down near the lower left corner of the keyboard is a key marked FN. Hold down the FN key and press the F9 key. That will turn the mouse pad back on.
It's possible that this is a hardware problem, but it sounds more like a loose connection to me. Start by removing the keyboard and checking all visible connections. You should be able to see the touch pad, keyboard, and screen connections with the keyboard off, and, yes, I realize that you cannot check the keyboard connection with the keyboard off, but you can when putting it back on. For some reason I keep getting people that love to point out the obvious lately, so I'll throw that in there right off the bat. Also check the hard drive to see if it's seated properly. If the problem persists, you may need to take the cases apart and check all connections on the board.
You need the password to unlock it. If yo don't have it you are out of luck. Password is stored on a separate chip and needs special tools and knowledge how to replace it.
If your laptop's memory can be upgraded there is usually a small panel you remove under the laptop. Then you need to tell some one at the computer store where you buy memory chips the make and model so they can give you the right chip.
Most notebooks have touch sensitive pads or switches underneath the keyboard, unlike a normal keyboard which is less complicated.
You can try and remove keyboard and check underneath, but it may be that the circuitry that works certain banks of keys is damaged or shorting.
Not a job for faint hearted i would recommend a qualified repairer.
