Question about Dell Computers & Internet
If your laptop won't turn on, you could have any number of problems. The problem might be a genuine power issue derived from either battery failure or simply a loose AC adapter. Conversely, it may only appear to be a power failure, and the problem may lie with another component. Errors in brightness settings and LCD display malfunctions can both make a laptop appear to be powered off, and all these problems will need to be corrected. Look at the battery indicator light on your computer. Is it on? If so, check your brightness settings. If your laptop appears that it is not on, it may in actuality have lowered brightness settings. If the brightness setting is at its lowest setting, the laptop screen will be completely dark, and the laptop will appear to be powered off, even though it is not. Try cranking up the brightness settings. Check your AC power adapter. Is it snugly plugged into the wall or surge protector? Make sure the connection is made and it is not loose. Also, try connecting the power adapter into a different wall outlet. Check the status of your laptop battery by considering how long you have had the same battery. Most modern batteries are only good for about 1,000 full charges. After that point, the battery can and eventually will greatly deteriorate. Replace your battery if necessary. Replace your battery by powering off your laptop and then flipping it over and locating the battery cover outline, which will be near the bottom back of your laptop. Remove any screws with a Phillips screwdriver and pop off the battery cover. Slide out the old battery. Put in the new battery by sliding it in until it clicks, and then replace the cover. Consider replacing your laptop monitor. Your laptop may power on, but if the monitor display does not work, it will appear to be off and you will not be able to operate the machine. Check to see if your current LCD display works by plugging your laptop up to an external monitor using a VGA cable. If the external monitor displays your computer contents, your computer motherboard and underlying systems are still working, but your display will need to be replaced. Replace an LCD display by removing the screws around the bezel of your current display with a Phillips screwdriver. Pop off the bezel carefully and remove it. Then, locate the screws on the two metal brackets beneath the bezel and on either side of the display, and remove these too. Disconnect the inverter cable, which is plugged into the inverter. The inverter is located just beneath the display, at the bottom-center of the laptop. Then, pull back and slide out the old display, and replace it with the new. Put the metal bracket screws back in place, reconnect the inverter cable, and then pop the bezel in place. Replace the bezel screws. Hope this helps.
