How do i fix a split screen of my Toshiba c600d-t36b laptop


The quickest way to change the display output settings is to use the
display hot key (Fn + F5):
1 Press Fn and F5 simultaneously.
2 While holding down Fn, press F5 repeatedly until the setting
you want takes effect. Briefly pause each time you press the F5
key to allow time for the display to change.
This hot key cycles through the settings in the following order
(the last two options are available if an external monitor is
connected):
? Built-in display only
? Built-in display and external monitor (simultaneously)
? External monitor only
? Built-in display and TV (or other external video device)
? TV (or other external video device)
? External monitor and TV
? Built-in display and external monitor (extended mode)
? Built-in display and TV (extended mode)
? External monitor and TV (extended mode)
? Swap-Switch primary display between internal display
and external monitor when using extended desktop

All the lights come on when I switch on my HP Pavillion dv9600 but the screen is blank.


DO THIS FIRST - Perform a hard reset If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.
  1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
  3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Actions to take after performing hard reset If no error message is displayed:

If a text error message is displayed, see Troubleshooting Error Messages on a Black Screen During Startup or Boot c02076104.jpg

Black Screen with No Error Messages Connect an external monitor c02076105.gif If there is a problem with the LCD display's back light or a corrupted graphics driver, the display may appear blank but the notebook may be displaying information. Attach an external monitor to test the display. If the image displays on the external monitor, there may be a graphics driver conflict. To resolve this, turn on the computer and press f8 key, then select Enable low-resolution video . If the image displays on the LCD display in low resolution, you can download and install the latest drivers for your specific graphics driver. If there is an image on the external monitor but the notebook display remains black, contact HP for technical assistance. Disconnect all peripherals and repeat the hard reset Even though users are instructed to disconnect all peripheral devices from the notebook when doing a hard reset , some devices are often overlooked. c02069237.gif Double-check that all devices are disconnected including: external keyboard and mouse (wired or wireless), USB connected external drives and devices, thumb drives and flash drives, network storage devices, PC card, SD memory cards, express card, eSata connections, firewire or similar devices, printer, scanner, camera, port replicator, or docking station, any CD/DVD from the optical disc drive, and any media from the multi-card reader.B

My screen went black while i was working on it and shut down. went 2 power up an no video. any known problems with this model gateway.


Firstly, I would suggest you to try it on another another/External Monitor through Vga port or Hdmi port if available (I can't make it specific since you didn't mention whether your system is Laptop or Desktop). If the video/display shows up on the external monitor, then the problem is with the Lcd of your computer. In most cases, it can be repaired. It'll only need to replaced some parts, maybe capacitors or inverter or backlight led. While the machine is On, look at the display very carefully, and check if you can see the display even if it's dark or not. If you can see the display without light, the problem is with the Backlight, replacing the backlight tube will fix it. But to do this, you'll need to know how to disassemble the monitor/display and how to fit it. All electrician's materials like soldering iron, soldering paste, soldering wire, screwdrivers should be ready. I would suggest you to call and bring a technician or visit a service center.


If the video/display is not showing on the other monitor/external monitor, then the problem is with the system inside the box/case. To start troubleshooting this, first turn off the machine, remove hard disk, Cd/Dvd drive, Ram/s and boot again. Can you see anything on the display, if so, the problem is with one of the removed units, first install the Ram and reboot the system, and then followed by Hard disk and Cd rom. Most problem with no/dark display is related to ram, in rare cases (if unfortunate it with the Bios chip on the motherboard). Sometimes display/video card. If Ram isn't the problem, then your best option replace the motherboard. Some service also repair laptop/desktop motherboard. You can contact Gateway for more details using this form (click here).


If you follow the above instructions correctly, you'll be able to find out the source of the problem.

I wish you good luck.

Thanks for using FixYa.

My hp notebook dv2201ca power on by itself, but lc...


Hi, to isolate the issue perform the following.

Step 1: Hard Reset
To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.


Step 2 :External Monitor
1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook.

Aspire Notebook 5735-4774 won't display on external CRT monitor


If the video chip on the Aspire motherboard is OK then the image on the external monitor would be OK. If not then the video/motherboard is faulty.
To gain access to data on the hard disk, remove the hard disk and connect it to an USB hard drive adapter and plug it into a working computer's USB port. The computer will see this as an external hard drive.
Alternately -
You can put the hard drive in an USB hard drive adapter case and use it as an external USB hard drive.

Have you tried cycling all the way through the options with the F4? Most laptops toggle in a manner similar to: 1) Laptop only, 2) External display only, 3) Both displays, 4) Back to Laptop only (cycle repeats).
