Toshiba satellite p105-s6227 built in and external monitors not responding


Your Graphics Adapter may be bad. You didn't post the results of the screen testing in another laptop? Did the screen work? Has the laptop been overheating due to dust build up in the fan, vents, heatsink? Has the Thermal Paste degraded/overheating causing a failure of the Graphics Adapter? When you boot does the HDD blink? Sound? Fan spins? Just no monitor? Any damage? drop? Possible loose connection of the Graphics?

Acer is going straight to a black screen after the acer logo in startup....it just shows a tiny blinking line. It goes no farther. I need help fast


Apparently your Acer cannot find the operating system. As soon as the Acer logo comes up, there should appear in one of the bottom corners "F" & a number should appear. Immediately start pressing that F number (top row of keyboard). This should take you to a boot screen. Scroll down to boot sequence. Hit enter. Make sure boot-up sequence is CD or floppy drive first, second should be HDD, then escape. Restart computer. Should then boot off CD drive. I am assuming you have an operating system (XP, windows, etc.). Let me know if this doesn't work.

My laptop screen is black and caps lock and scroll key are flashing


That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443366&lc=en&dlc=en&cc=uk&lang=en&rule=26781&product=3816592
This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008. On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes. The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved. Battery power LED blinks The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition. Battery Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help. Caps Lock/Num Lock LED Component Tested Error Condition LEDs blink 1 time CPU CPU not functional LEDs blink 2 times BIOS BIOS corruption failure LEDs blink 3 times Memory Module error not functional LEDs blink 4 times Graphics Graphics controller not functional LEDs blink 5 times System board General system board failure LEDs blink 6 times BIOS BIOS authentication failure

Toshiba satellite a135 monitor goes black


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Vostro 1000 black screen an i can hear it running, but can see..


A blank screen with evidence that the motherboard is working (the Capital "A" green light is probably the CAPS LOCK on your computer's keyboard) initially points to an output or video problem. One quick way to see if that is the case is if you connect the computer to an alternate screen. Do so with the "sick" computer powered off at first. After being sure the connections are snug, be sure that the test monitor is powered on and then turn on your "sick" Dell. If the test monitor runs as your laptop's monitor ran when it was healthy then you know there is a cabling/backlight/inverter/screen problem. Some of these can be solved very easily, some more expensively as replacement may be required.

On some laptops pressing down firmly on the keyboard may seat a screen cable to motherboard connection. That often works on IBM Thinkpads with screens that fade in and out due to a poorly seated screen cable connection to the motherboard.

So let's see how the test to a known working screen goes.

Toshiba a75 s-206 problems helppppppppppppppp


Sounds like a bad hard drive to me. Take out the hard drive completely from the laptop and boot up with the windows xp cd and it should go past the blinking cursor. At that point you know you'll need another hard drive.

Toshiba laptop- error upon start up-


I'm sorry to say that it looks like the hard drive is going or has gone bad. You can try removing it, and checking to see if it could be loose, but in virtually every case that I've seen this, the drive was dying.

If you can connect the drive to another machine as a secondary (you may need an adapter if IDE, Sata would work directly) drive, you may be able to pull some or all of your files, if the drive has not completely gone bad, and assuming where it is going bad is not where your data is stored.

The good news is that if you buy a new drive, you will need to reinstall your OS and applications, but it is likely that the machine would then work fine.
