|If you have dropped the netbook, or have spilled liquid on it, those things are the most common reasons a laptop or netbook gets damaged such that major parts need to be replaced. |
Most more recent laptops (and netbooks) will not boot or will not fully boot if only the AC adapter is connected to it. The main battery must be installed when the AC adapter is connected, and the battery must be capable of being charged to at least a minimal level, and must be charged to at least that level.
If you get video before Windows is supposed to load, the computer is okay but you have a problem with the hard drive or just in Windows.
If you get no video at all,
- if the hard disk led seems to be flashing as it normally does while booting, your problem may be that something regarding your built in display has failed. (If you normally need to Login to Windows, the hard drive led will stop flashing shortly after that point)
- if the hard drive led does not flash, your problem may be related to a problem with the main battery or the AC adapter or the jack in the netbook the AC adapter plugs into.
Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.
See response 1:
DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.
Some laptops will display on an external monitor without you having to do anything.
If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / sometimes both / built in display video only - see the Owner's or User's manual for the model.
If there is nothing wrong with your AC adapter or it's connection and the jack in the laptop.......
Laptop main batteries usually work as they should for a year or so, then they begin to rapidly deteriorate. From what I've seen, by two years they cannot be charged to anywhere near their full capacity, and it gets worse after that.
They often develop internal shorts when they are older. If the battery gets HOT rather than just warm after you have attempted to charge it for at least a half hour, or after you have been using the laptop for a while with the AC adapter plugged in, it's definitely internally shorted and you must replace it. Internally shorted batteries getting too hot have been known to cause the laptop to catch on fire.
