Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

Well it is most likely a issue with the Video driver as you are able to boot to the safe mode.I would suggest going back to the safe mode and deleting the present driver for the video from the device manager.before you restart the system just download the latest version from the support.dell.com so that you can reinstall it.Also check in the graphic properties which screen is set to be the defuat.Incase still not working i would suggest reinstalling the operating system before replacing any hardware.

SOURCE: Toshiba Satellite P200 doesn't boot

Try pressing FN/F5 keys simultaneously, or the key that toggles internal/external Display. Look for the double screen Icons on the keys.

Tap the Pause Key.

Restart and press and hold F8 key when Toshiba logo appears. When the boot Menu appears, select Last Known Good Configuration.

If all else fails ther should be a reset button on the side of the LT. Consult owners Manual for location

Do the following without the battery inserted.

Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...

Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.

These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.

hello

these links below have information (drivers, solutions) for your laptop, that will assist you.. review them , i am sure this will give you background causing BLACK display on your screen.

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.

SOURCE: HP G61 NOTEBOOK PC BIOS

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/

My windows XP OS won't recognize my SimpleTech SimpleDrive Pininfarina 300GB External USB 2.0 Hard Drive


I found that often, external hard drives just don't have any active partitions and thus don't show up in Windows. Go into the control panel, administrative tools, computer management and then the disk manager and see if it has a partition. If it's just unallocated space, right click and make one.

Is your laptop booting on switching it on, ie, it is showing hard disk activity and shows initial boot screen. If yes, while switching on press F8 button very frequently. You will get a screen showing the options for booting. Choose a safe mode option and restore your computer to an earlier date. This may solve your problem. On the other hand just switching on the computer shows monitor with yellow and black stripes, you may have to take it to a service center.

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 samsung r519 wont turn on. when i press the on button i here the fan going, yet the screen stay's black and only the power light comes on. what could the problem be?


Does the fan stay running? if it does! it is probably a motherboard issue, if the fan is working correctly it should wind down, and if the hard drive is working "hard drive light will flicker" hook a external monitor to the video output on the back of your laptop if you see windows boots up then it would indicate laptop screen problem, but if the fan and the power light are the only activity then the motherboard is the problem.

Black screen on booting my Compaq 610 notebook


If it seems like you're accessing the hard drive (drive light comes on, flickers intermittently, then goes off, it's a good chance your screen is bad.

First thing to do is plug in an external monitor and start up the laptop. If it comes up with windows, you know it's the screen.

To find out if it's the backlight, or the lcd, toggle the monitor function and shine a flashlight on a slight angle to the screen. If you can faintly see what was displayed on the external monitor, then the backlight inverter is probably bad.

If the external monitor didn't come up, you're probably looking at a motherboard.

The good thing is that all of those are covered for one year under Compaq's warranty, on a new machine.

If you are able to use the external monitor, back up your data, because HP/Compaq usually reformat the harddrive. Additionally, if you've added memory, pull the cards. They want it sent back the way it came from the factory.

If the problem is with the RAM or Hard drive then atleast you will get the access to the BIOS and this is not related to the hard drive or RAM as there is no display on the notebook.
If the Quick launch buttons are glowing then perform the following:
1. Remove the notebook battery and disconnect the AC adapter. 2. Press and hold the power button for a minute. 3. Reconnect the battery and AC adapter then try to turn on the notebook.
If the display still doesn't appear then, connect the notebook to external monitor and check the display on it. If there is any display on external monitor then the issue is with the LCD screen. If there is no display on external monitor then the notebook needs to be diagnosed by a technician at the service center.

Compaq e500 boot up problem


If it were my laptop here is what I would do: 1. Install a new hard drive. 2. Install the operating system. 3. After an anti-virus program was installed and updated, I would connect the old hard drive to the laptop using one of those external USB hard drive adapter cables. 4. If the old drive proves to be readable, copy documents/photos/bookmarks to the new hard drive. Hope this helps.
