dell vostro 1015
NO OS stated, at all. by OP or Hyjackers.
the dell site has xp vista and w7 driver only for this old PC
if the device manager shows, keyboard drivers missing then try the one below marked,
Mouse, Keyboard & Input Devices 07 Jul 2012

below covers both types of personal computers.

oops dell lost the users manual after 9 long years, sadly
see the 2 keys below, blue, sun Icons
you push Fn blue key left side of keyboard
then push SUN key down. lower red arrow below.
if this fails to lower the backlamps
that means the drivers are missing. xp,.vista,w7 are all dell supports. (NO OS stated by OP nor hyjackers. as is par here)
Fn+down-arrow : key. if dead driver is wrong.!!!

You can download your product's instruction manual here.

are you pressing the Function key first? the brightness buttons do not work without pressing that first. usually it is in blue close to the ALT.
& Win key
You can also change your brightness from the control panel, click on display then color setting, and you can see the contrast and brightness, as well as gama that does make it brighter or darker as well. Remember to write down the default settings.
these will not affect playing movies, the brightness adjustment for that are different controls, they can be access by the right click on the mouse during playback

Adjust your monitor's brightness and contrast

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.)

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor.

Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.

Brightness and contrast symbols

On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.

Laptop display. Laptop displays don't have brightness or contrast buttons on the front.

For a majority of laptops, there isn't a control for setting the contrast.

However, you can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness ( ) or increase brightness ( ).

http://windows.microsoft.com/en-US/windows7/Calibrate-your-display#

When using Display Color Calibration on a laptop, set the display to the maximum brightness setting.

Adjusting brightness automatically using adaptive brightness

Adaptive brightness is a feature in Windows that uses a light sensor to automatically adjust the display brightness to match the lighting conditions in your computer's surroundings.

To use adaptive brightness, you must have light sensors installed and enabled on your computer.

To determine if your laptop or computer monitor supports adaptive brightness, look for the Enable adaptive brightness setting in Power Options (mentioned in the following procedure) or check the information that came with your computer.

To turn adaptive brightness on or off

Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.

Under any plan, click Change plan settings.

Click Change advanced power settings.

In the list, expand Display, and then expand Enable adaptive brightness.

To turn adaptive brightness on or off when your computer is running on battery power, click On battery, and then, in the list, click On or Off.

To turn adaptive brightness on or off when your computer is plugged into an outlet, click Plugged in, and then, in the list, click On or Off.

Click Apply. Click OK.

hope this helps

The BIOS in the ACER determines the maximum size of the hard drive it can support.
Check the laptop's specification to see the max size you can install in this model laptop.
It appears that the max size your laptop can support is 140 Gb (unformatted). 137Gb formatted.

I suggest you install a hard drive up to 140 Gb capacity in your laptop and place the 320 Gb hard drive in an USB hard drive adapter case and when you attach this hard drive to the USB port in your ACER laptop then you will be able to get the full 320 Gb capacity after you delete the partition and create a 320 Gb partition and format the hard drive.

you can format size with allocation unit size set it to 4096 size and set partiton type to fat32.
Let me know if you need more assistanse.
thanks.

you need to go in to the bois and click on the boot up menu then the 1st boot should the usb then it will pick up your xp disk
