Question about Toshiba Satellite A135-S4527 Notebook
I turn on the computer, it boots up windows, I can barely see the desktop or the mouse movements.
First check your brightness settings and restart the computer and charge it fully and turn it off overnight and all that good jazz. I'm guessing that this is more complicated though.
Laptops are lighted with small fluorescent bulbs, like the 4ft. bulbs in overhead lighting in office buildings but much smaller. My guess is that this bulb failed or (maybe more likely) the part of the computer that creates the charge for this bulb failed (the inverter board). Fluorescent bulbs require a high voltage to get started (around 600v) and this inverter board turns the 5v charge on the motherboard into the 600v required to start up the bulb.
The good news is that most computers have an inverter board that can be replaced.
You should check ebay and google for specifics on the inverter for the A135, HERE'S ONE on eBay that would not be too difficult to replace if you don't feel squeamish about opening up the LCD case of the laptop. You could also try contacting someone on Craigslist or at your local computer repair shop and have them do it.
Whoever does this should first check to make sure the light bulb is not burned out and that the inverter board is getting the proper incoming voltage.

Troubleshooting a mouse that scrolls up and down uncontrollably depends on various factors. Possibilities extend from the class of surface to hardware problems or configurations.
A variety of laptop mice exist.
A mechanical mouse uses a hard rubber ball that rolls with any movement of the mouse.
An optical mouse uses an LED sensor to detect movement.
An infrared, cordless mouse requires and relays a signal to the mouse port found on the laptop.
The base of the trackball mouse remains stationary, while the trackball sitting on top of this mouse reflects all movement.
A mouse depicts a device that controls the movement of the cursor or pointer on a monitor or display.
Several reasons exist for a cursor to uncontrollably scroll up and down on a display.
Static electricity often initiates wild cursor reactions.
To solve this, use pre-moistened computer cleaning wipes to help control static electricity and clean electronic surfaces.
Bad batteries can trigger impromptu cursor movements in a wireless mouse.
Electrical interferences can also produce the scrolling effect. Radio, wireless or electrical objects may require removal from close proximity.
The mouse needs to stay in range of the receiver, meaning near the Laptop
I have found that the best way to adjust your mouse settings is to create a control panel in your bottom toolbar scroll to the bottom of your screen right click you will see an array of options select the toolbar option then select desktop
then you will see the desktop in the bottom toolbar select the 2 >>arrow heads then all control panel items then select mouse this is in WINDOWS 7
in XP you will have to select the new toolbar option once you have that a browse option select my computer then control panel then a control panel option will be in the bottom toolbar
click start right click on my computer select properties device manager control scroll to mice and pointing devices you might see a yellow question mark? right update driver
click on >> control panel all control panel items mouse you should see 4 tabs buttons pointers pointer options and hardware under hardware you have options to troubleshoot also you can select properties under driver you will have the options update driver rollback driver or uninstall in xp
in windows 7 click start control panel hardware and sound mouse you will see the same tabs and options as with xp
hope this helps
