You have a BIOS error but before adjusting anything, make sure there is no USB things connected or LAN cables plugged in and no cd in the player and re boot it.
If the choice screen of F2 or F12, press F2 and select default settings.
Re boot again. That should fix it.

Welcome to FixYa!
There are 2 process you could used when it come to cases like this:
1. If its the power settings causing this just follow this steps. Here are the steps:
  • Turn off your computer and unplugged all wires connected to it (including power).
  • Remove the battery from the bottom of the computer. There will be two tabs labeled 1 and 2.
  • Re-plug in the power wire. (the battery should not be in the computer) Turn the power on. The screen will work. Choose start windows normally. (if you get that screen).
  • Go to the start menu then click Control Panel -> (Mobile PC) -> Power Options -> Under Balanced choose change plan settings.
  • Choose Change advanced power settings.
  • Find Processor power management and change the minimum processor state from 5% to 100% for each On battery and Plugged in. Click Apply then OK.
  • Shut down the computer and removed the power cord.
  • Re-install the battery on the bottom of the laptop, plug in the power cord, and restart the computer.
2. If its the boot files being corrupted as the one causing this, you could used this as well.
First BACKED UP your files to an external hard drive using Puppy Linux. You could used this link: (http://www.puppylinux.org/)
Once you are done backing up your file then follow this:
  • Booted up the computer and pressed and held down F12 (boot)
  • Insert the Toshiba recovery disc (there should be a disc one and two).
  • Selected CD/DVD from boot menu
  • Go to Toshiba recovery wizard then go to the second option (format/delete everything off of hard drive)
  • Restart the computer
  • Re-load the disc
  • Select Toshiba recovery wizard and then select the first option.
  • Once the wizard began, wait until it asked you to insert disc two. Continue from there.
Hope this helps you. Have a nice day and thank you for using FixYa!

I have a Toshiba A505-S6960 laptop. Never have had a problem until today.......when I turn the laptop on it goes through the boot process but only makes it to the Toshiba logo screen with the F2 and F12...


It seems that your computer is not seeing your hard drive. This could either be because of bios settings or more likely because the hard drive has failed. If the unit is under warranty, call Toshiba support and describe the issue to them. If not, places like Best Buy can determine for sure the cause of the issue.

Laptop toshiba satellite p200 bw5 screen goes dark as if darkness/brightness was adjusted - but not Thanks


An LCD screen cannot produce enough light by itself. It needs a Backlight to help illuminate the screen.

Power for the Backlight is produced by an Inverter. An Inverter also provides power for the LCD screen.
It reduces voltage for the Backlight, and increases Voltage for the LCD screen, from the laptop's power.

Most of the time a dark LCD screen can be attributed directly to a bad Inverter. (Around 90 percent)

A Backlight is a CCFL.
Cold Cathode Fluorescent Light.
VERY similar to the fluorescent lights you see used in residential, and commercial applications.
(Homes, and businesses)
Only on a MUCH smaller scale in physical size, and needed power to operate.
When a Backlight goes bad, it just goes all at once. Not goes dark as you have stated.

(Your statement meant to me that you power on the laptop, the LCD screen shows well, then goes dark)

How to install an Inverter in a Toshiba Satellite P200 series laptop,

(You can click on each individual photo to enlarge. You are on Page 1. Page 2 is accessed at the bottom, by clicking on it. Page 1::Page 2::Find another model)

Just one of many places that offers an Inverter for your Satellite P200.

NOTE*
1) ALL power removed from the laptop before beginning.
AC adapter (Charger), and Battery.

2) The screws you will remove, may have screws that look alike, but are NOT.
Do Not mix them up.
For this reason it is suggested to use a multi-compartment container, and label the compartments for where the screws came out of.
You can use a clean egg container, and label the individual egg holders, in a pinch.

IMHO it isn't hard to perform this repair, and you can do it. Save yourself money.

Does Not Turn On


First thing you're gonna want to try is reseating the memory.

Second, see if you can get into the bios by pressing F2, F10, DEL key it depends see if you see something on the screen, sometimes pressing ESC does it. It all depends.

Try that first and let me know what happens.

Answer to your question


You will need to get into the bios, and set the CD drive to boot before the hard drive. Since your in this uncompromising loop, remove the hard drive, then start the machine. It should go to the initial Toshiba screen and you will see the prompt on what to press to get to the bios, or utility set up. Once your in the bios, find the boot order and set the CD drive over the hdd. Then put the hdd back in, the recovery or operating system disc in the CD drive, and start the machine. It should now boot from the disc. At this point you will want to do a system repair. If the repair doesn't take, then reformat the hdd, and install a new operating system. If the hdd will not format or you have any issues during or after the install, then the hdd has failed and will need replaced. If you need any futher aststance, just ask.
