First turn wifi on using functions keys (I think Fn+F11). A little icon will show at the bottom right task bar which will have a picture of a pc monitor with a red X symbol. Right click on this and select View available wireless neworks. Once you have that, you will see what you can connect to and simply connect. Please remember that you will always have to turn wireless on using the function key everytime you start your laptop again because for power saving it switches it off everytime you turn your laptop off
Hi, First of all you have to determine if the problem is the GPU (graphics processing unit) or a possible bad connection on the inverter.
To check this you will need to plug an external monitor to the laptop and use the keyboard toggle to switch screens, usually its hold down Fn and press F6 or the F key with a monitor icon on it.
If the external monitor comes on then the problem maybe the inverter.
To check this remove the screen bezel (plastic screen surround). At the bottom of the screen you will see an
elongated piece of circuit board with wires coming from either end
covered by frosted plastic. That is the inverter, check the connections on the inverter (both sides) and power the laptop up to check the display, to remove it
gently pull the plugs from each end and remove the screw from the
middle and pull the board away. Look on the back of the inverter itself for a copper coil, if you
re-solder the solder points around the coil you may find it works again
as components that suffer from extreme heat the solder joints dry
causing bad connections, re-floating the solder solves the problem in
90% of cases.
You could be expierencing a problem with your monitor screen. try this.... connect another monitor screen to the VGA port of your laptop. Now try booting up. Look for and push Fn + the key that turns on a secondary display. if the monitor screen comes on. you need
another laptop monitor. At least you can use your laptop with the second monitor for now.
If you go into control panel and check out your power options. Make sure that your system is set to never shut off the monitor. This will of course waste battery power (if you run off battery) so you will have to decide which is best for you.
If the power settings are not to blame then maybe you do have a hardware issue. Some laptops have a hotkey combination that if coincidentally you are typing and you press the right key combination you send it into hibernation. You can check this via the power settings.
Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.
I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.
I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.
