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.

Why wont my zeepad turn on


Check the battery is charged - it may be duff and nee replaced if it is not charging or your power adaptor may not be charging it - check it with a multimeter - the power socket on laptops andf tablets are very susceptible to damage - if that fails then plug it into a pc using the usb port - it will charge very slowly as usb only has a very low charge current but be patient and if it charges up after 12 hours using the usb method you will know one way or another whether its the battery or the power socket or charger.

Camileo P10 charging problem


I had the same problem with the P10 not charging via USB, I purchased mine second hand so it came with no charger. I assumed it would charge by the USB cable but it did not, the red light flashes but doesn't charge. Luckily I have an external battery charger for a different camera i got some years ago that takes a similar battery , the P10 battery didn't fit properly so I had to place it at a 45 degree angle into the charger making sure the outer contacts were lined up properly and taped it into place. After an hour it was fully charged and the camera is working fine. The charger is a 4.2 volt charger. New external chargers can be picked up on ebay cheaply

My Dell Latitude D820 has many problems.... The biggest one is that I came home from work to turn it on, and the screen is black... When it turns on, it is completely white. I am so upset! I just got this...


Screen issue:
It sounds like either the lcd screen or video card inside the computer is bad. To isolate the problem try connecting an external monitor to the laptop. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the external monitor displays ok that proves your video card is ok and your lcd screen is the problem. If the external monitor displays the black or white screen like your lcd screen then your video card inside the computer is bad. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Laptop hot:

Some laptops and the ac adapter get very hot. If the laptop is not shutting down, then it is not overheating, so don't worry about it. You can buy a laptop cooling pad that has fans on it and it plugs into one of the usb ports on the laptop. The laptop sits on it to keep cooler.

Your battery is probably dead so that is why you can only power it up using the ac adapter power cord. Once the power cord is removed, the laptop will turn off. Batteries only have a useful life, and after that, they have to be replaced.

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.

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.

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.

Audiovox SMT 5600 will not charge


If your battery goes COMPLETELY dead, which it will do if phone is not turned OFF and not used for a long period of time, you will need to JUMP START it using you OEM SMT-5600 AC charger. Other AC chargers will not work for this purpose and neither will a USB port.

You can JUMP START the battery using a USB port by cutting off a USB cable to expost the red and black power USB PORT power pins 1 and 4. Remove your SMT-5600 battery and while the modified USB cable is plugged into your USB PORT, hold the BLACK wire to the negative (-) terminal and the RED wire to the positive (+) terminal for about a minute. Replace the battery in the phone and connect the phone to a USB PORT using a standard USB cable. The SMT-5600 charging light may not register for a while, but will eventually light amber to show it is charging, assuming your phone is recoginzed by your computer.

Note some mini USB cables DONOT carry the USB power leads through to the phone, only data. If you have a very thin USB cable, be suspicious the power leads are not being carried in the cable.

Since the USB PORT power is limited to 100ma it cannot hurt the battery, but will insert enough current into a totally flat batter to cause the battery to register a voltage large enough to alllow USB PORT charging, typically 3.7VDC.
