Testimonial: "I meant left hand corner at the top. Hi I'd Sharma, thanks for responding, okay but I don't have n VGA cable plugged in to the laptop when doing this. Do you mean that when I switch my laptop on I should have the VGA cable connected? Then it should start up normal?"

SOURCE: black screen, blinking cursor in top left hand corner

Could be a number of issues, incl unseated processor or a faulty hard drive. First off I would remove mains & battery, remove covers from underneath and reseat any memory or processors you can find - by reseat I mean just take out and put back.If this fails, I would look to price up a new hard drive before condemning the machine.

Hello.

Either you have an operating system problem.or memory issue.

First, try Safe Mode again (press F8 repeatedly when powering on). Go to System Restore and choose a date when your system worked OK. Note: with System Restore, all your updates will roll back to that date. Follow the process.

If still a problem, disconnect all cables. Be certain to dispel static electricity by touching metal. Flip the laptop and remove the battery. Remove the memory cover. Try reseating (removing and reinserting) your memory (try one module at a time to test).

It's also possible that your Master Boot Record is corrupted. To fix:

1. When prompted, boot from the CD drive by pressing any key. If Windows loads automatically, you will first have to enter the BIOS setup and change the order of the boot devices to start with the CD drive.
2. Once the setup loads, you will see the option to press R to repair a Windows installation.
3. Once the Recovery Console loads up, you will have to type in a number that corresponds to your Windows installation. This is normally just 1. Press Enter and then type in the Administrator password (no password, just hit Enter, unless you changed the password).
4. Now at the prompt, type in fixmbr. Your damaged MBR will now be replaced with a new master boot record and your computer should now be able to boot properly. Also run the fixboot command to repair the boot sector with a new one.

If still a problem, the last choices are Factory Restore and reinstall. Accessing Factory Restore (restores to the factory settings and will wipe out anything that you have installed or saved on your PC), is dependent on your hardware manufacturer. Boot your system and press F10, F11, Alt+F10, or Ctrl+F11 to access Factory Restore. Follow the prompts.

If still not resolved, you'll probably need to reinstall your operating system.

Hope this helps.

Hard resetting


The trick is sliding the display lock switch at the exact right moment, otherwise it will not engage. Here are the steps that have worked for my self and several other Xoom FE owners:
1. Power off the unit - if not already
2. Hold down the "Down" volume button at the same time you hold down the power button for 3-5 seconds.
3. While still holding down the "Down" volume button, release the power button and toggle the display lock slide a couple of times (located next to the volume controls).
4. The display should now show "Booting Recovery Kernel Image" and then the Android Robot will be displayed when the unit is in the rebooting phase.
5. Since the device is being Reset (erased and re-imaged), it is normal to see "Please wait for pre-load data" and this process takes about 6-8 minutes. The Xoom FE is now being Factory Restored to the original image.

HP laptop screen is black


A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector. Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken. If the monitor doesn't work, the motherboard or video card might need to be replaced. Hope this helps

I just opened my tablet iconiatab a500snid12914106415 and the home button does not seem to work


there is no physical home button for the iconia. it has power to left. you have to hold to activate. hdmi to lower left. volume is on top. next to volume is rotation lock.. to the right is power and bottom right is usb ports. on screen will be back button, home button. and options button. since these are onscreen you could turn off rotational lock and press onscreen button on a different side.

Hold the power button for 5 seconds or more - does it turn off properly? If so, can you turn it back on afterwards?

Take out the battery and unplug the power adaptor. Let it sit for a few minutes. Now try the power adaptor alone. If this works, try shutting down and running on battery again.

The screen just went black and i can't turn it off the power button and blue maintenance button just stay on


When the Thinkpad locks up and you can't shutdown the normal way, just press the power button and hold it down until it switches off. If that doesn't work just remove the battery.

There is a concealed switch situated just to the right of the right hinge, which is activated by a cam on the screen bezel and acts as a sensor for lid open or closed, it also turns off the backlight, so if it sticks in a closed position, the backlight will not turn on, either free the switch, or disconnect it, it connects to the small power board (under the cover with the power button and 5 funtion buttons) i hope this solves your problem. ..... ****
