Hey, i got a lenovo p500 and the FN + SPACE key combination that's supposed to work... doesn't. It might just be the inverter that's out, but i want to be positive that it is that part bef

I just got it a couple of days ago. It was the display model... that's why I'm thinking that the inverter is out.

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :-

    Thanks, but it's my keyboard backlight that won't light up. My LCD backlight on my screen is fine.

How do I turn on the wireless switch?

The Lenovo IdeaPad Y450-534 PC Notebook is supposed to have a wifi switch at the front right side of the laptop. If this button isn't available, then ot wil be a combination of the fn button and one of the Function keys. There is supposed to be a blue wi fi icon on the Function key. On a Toshiba it would be F8.

Lenove ku-0989 fn key

  1. Numerous folks indicate that Windows doesn't register the Fn key as a keypress but using a tool that gives the ASCII value of a keypress I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table.

  2. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy.

Turn off the touchpad on the lenovo g530

You can simply press Fn+F8 key combination. If that doesn't work try to look for a button found on the upper rightmost corner of the laptop panel the press it. Or to make it simple, look for the power button, opposite side of it you will see 4 buttons, the right most button would be for the touchpad, Just press it. It should disable the touchpad and do the same to enable it back.

My lenovo s100 cant view my webcam..or it not dtected


If you're using Yahoo Messenger or Skype to access your webcam and it says No Camera Detected, the camera might be turned-off. Try the following:

1. Presss Fn+ESC (The Fn key is located at the left side of the space bar). that's the hotkey to turn your Webcam ON and OFF and try to check if your Webcam works.

2. Open Device Manager - press the Windows Key+R and type devmgmt.msc on the keyboard (the windows key looks like this ray_tosh_1.jpg ) and look for Imaging Devices


3. If you see your webcam there, try to right click on it and Uninstall and restart your computer and check if your webcam works now.

If that still doesn't work and the webcam light is not turning ON, that's already a sign that your webcam is failing and needs to be replaced. If you're still under warranty, you can Call Lenovo Support at 1-877-453-6686 to have it serviced.

Good luck.

How to switch on wlan ?


You can turn ON the WLAN in two ways. The most common way is by flipping the physical WLAN switch ON. The switch is usually located at the front side of the computer (look below the light indicators at the bottom of the touchpad or at the left / right / side of the computer. On some computers, they're above the keyboard.

If that won't work, you might wanna try a combination of function key (Fn+ wireless key).
For Toshiba laptops it's Fn+F8, and for Lenovo it's Fn+F5, Dell and HP usually uses Fn+F2 but every brand has a different combination so check the F1 up to F12 keys for the wireless symbol.

Maybe you've activated the number lock in the letter keys, try to push another time Fn+NumLock or (try) to tell us the model of the notebook; if that combination doesn't work check the color of "Fn"on the key and search for a block num symbol on the others keys, then push both together.

Screen on Aspire 3000 is very very dim

Backlight or inverter failure sorry to say. No telling which without substitution. Backlights are mostly built into the top of the screen and are tricky to replace. Inverters are generally sited at the bottom of the screen under the facia panel. Look around ebay for replacements
