I'm sorry to say that it sounds like either the AMD CPU has failed or some very early chip on the motherboard.
The opening of the DVD tray is dependent only on the non-rotation of the drive and one power supply voltage so is not an indicator of life of anything else.

How can i get my sylvania netbook to work when i turn it on and it wont do anything all it does is stay at a black screen? Need help with my sylvania computer problems


When you plug in the power cord do you see any lights either on the power cord's adapter or on the computer that indicates that the power cord is plugged in? If not, your power cord might be bad. You might have been running off your battery for the last time you used it and since the power cord was bad it was not charging your battery so it eventually drained all battery power.

When you turn it on do you hear any fans running, any hard drive running, cd drive clicks once and you see the light on the cd drawer come on for a second or two, lights anywhere on the computer? If so these are signs that the computer is trying to boot. If not you might have a motherboard issue.

Static Charge Buildup can also cause the computer not to boot. Remove the power cord and battery from the laptop. Press and hold the power button for 30 seconds then put the power cord back in (leave the battery out) and try to reboot. If it boots, you had a static charge buildup and can put the battery back in now.

Is the computer actually up and running but the screen is black? If so take a flashlight and shine it on the black screen. If you can bearly see the icons on the desktop that means your lcd inverter is bad and needs to be replaced.

If the computer is actually up and running but the screen is black, try hooking an external monitor to the laptop. You can use any type of monitor, even the big fat crt monitors as long as it has a vga cable to plug into the laptops vga port. You might have to press the FN (Function Key) and one of the F1 thru F12 function keys to get the image to display. Normally the correct F1 thru F12 key will have CRT/LCD written on it or it will have an icon of a display. Press and Hold the FN key then hit the correct F1 thru F12 Key to display the image on the external monitor. If it shows, that means your Video Card is ok.

If the computer is on and running but the screen is black, you don't see any icons on the desktop when you use a flashlight then your lcd screen will probably need to be replaced. It might be something as simple as the lCD Cable is loose or just needs reseated (pulled aloose then plugged back).

You'll have to take the screen apart to get to the lcd inverter and the lcd cables.

Most laptops have a "toggle":
* output video only to internal LCD screen,
* output video only to external HDMI port,
* output video to both internal & external.

Set the "toggle" to the best value.

My USB port power error message


This happens when anything draws over 500mA, of current, if it was working OK, before, and is working now but displays that message, or not working, well in any case it seems to have gone faulty, and somehow, is now drawing more current drain, the USB port can supply. It may have been spiked too.from all the plug/unplug especially if the safely remove hardware is not used.

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.

I have a toshiba satellite laptop the screen is black


Shutting the computer down could be done by holding the Power Switch down for 10 seconds, rather than unplug/no battery "solution". A blank screen is more often than not caused by the failure of the screen's backlight. Plugging an external monitor in the ext monitor port would verify the computer still works, and I am sure it does.

Screen not responding


can you hear any boot sounds?
(fan noise, harddisk rattling)
do the LEDs work (battery and charger , Hdd, CD/DVD-ROM-drive,WLAN)?
this would indicate it still boots up, but screen might be broke.

u lucky?
- remove battery pack! retry booting

if not, hook it up to another external monitor
(use vga-jack in the back of it)
reboot, wait for signal

- check if the the fan is jammed
(due to sand???)
this might cause overheat problem -
use compressed air to blow/clean the fan inlet

still no luck? it simply may be broke...

When the LCD is black and you can see a dim image on the screen then it is a black light problem. could be a faulty inverter but mosr likely a burnt out/worn out CCFL lamp. By connecting and external monitor to the video port, you can determine weather the video card is OK.
If you don't get an image on an external monitor then the video card is faulty and it is impossible to repair except by replacing the motherboard.

0701 usb over current on hc/port error


I had the same problem on a toshiba satellite u400.
Usb over current on port ... blabla..
Please press F1 to resume or F12 to install.
F1 just ended up in a screen asking to press F2 or F12 which did nothing.
F12 did nothing.

Rebooting the pc ended in a black screen with a flickering HD symbol.

To be able to boot again on the BIOS I had to remove the battery and disconnect the plug.
Once It restarted booting on the error USB over current.

Si I took a USB mouse and tried to boot with the mouse plugged in on port , then another ... at the third port the PC booted normally with no error :)

Don't have any idea why it became faulty but it's now solved for me.
