The fn button on my gateway is the last button on the left in the first row. You should have gotten a diagram with your netbook. Please look at it, it may be in your manual.

Screen is very dark


Locate the Fn (Function) key on your keyboard.
It may be on the bottom left side with dark blue letters.
Locate the two "brightness" keys near the top of the keyboard.
These will be in the "F" keys, possibly if F6 and F7.
They should have little sun pictures or something similar to indicate brightness.
Hold down the Fn key while pressing F7, or whichever "F" key your laptop uses to increase brightness.
Tap F7 repeatedly until you reach the desired brightness.
Fn must be held down as you continue to tap.
Hope this helps

Hi. Im changing my internal hd in my netbook. Im wondering if it can support a 1tb hd.. I have a gateway lt21 series and it was running under a 250gb.. Thanks


well the size of drive has a few issues that need clarification can you provide actual model number from under the netbook and operating system. Also what 1 tb drive are you considering. There is a subtle difference among them and not universally exchangable(no matter what they say)

let me know this information and then we'll find a quick answer

No video at power up


See if the problem is the graphics chipset before going any further.

If it isn't then the problem lies with the Video Cable, (Gateway = LCD Cable), or the Display Assembly.

The heading states Gateway LT2104u Netbook PC. This is what I'll be basing the solution on. However the main part of the solution, will apply to all laptops/netbooks.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port (Connector) on the Left side of the netbook.

[ External VGA display port.
This is an example of a VGA connector, (Port), and a VGA Cable,

http://en.wikipedia.org/wiki/VGA_connector ]

The external VGA monitor can be a CRT type, (Cathode Ray Tube. Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the netbook on.

By default the display should be shown on the external monitor.
IF not;

A) Press, and hold down on the Fn key, and at the same time tap once on the F5 key.
(The Fn key is at the Bottom/Left of the Keyboard. The F5 key is at the Top of the Keyboard)

No display still?
There are at least 3 display options;

1) Internal monitor of the laptop ONLY
2) Internal monitor of the laptop AND external VGA monitor
3) External VGA monitor ONLY

You may have to hold down on the Fn key, and tap the F5 key more than once.

IF, NO display shows up on the external monitor, you have a bad graphics chipset.

[ Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The GPU is the graphics chipset,

http://en.wikipedia.org/wiki/GPU

The GPU for a Gateway LT2104u Netbook PC is an Intel GMA950 ]

IF, display does show up on the external VGA monitor, you have either problems with the Video Cable, (LCD Cable), or the Display Assembly.

LCD Cable:

1) Connections;
The LCD Cable connects TO the motherboard, and TO the back of the LCD screen, in the Display Assembly.

IF, either connection is loose, you will have display problems.

Check both connections.
This requires partial disassembly of the netbook to access the motherboard side of the LCD Cable.

Also requires partial disassembly of the Display Assembly (Gateway = LCD Module) to access the connection at the back of the LCD screen.

2) Damage;
Observe the LCD Cable on the motherboard side. See if there are any obvious signs of damage to the LCD Cable's sheath.
The most susceptible area to damage is the area under the left Hinge.

However, the LCD Cable should be removed, and a continuity check of the cable should be performed with a multimeter, set to Ohms.

(By checking the connections, you are at a point anyway, that removing the LCD Cable should be no problem)

LCD Cable checks out OK?
LCD Module problem; (Display Assembly)

The LCD Module consists of the;
1) LCD Bezel,
2) Camera Module,
3) LCD Module Brackets, (Includes Hinges)
4) Microphone Module,
5) Wireless 3G Antenna,
6) WLAN Antenna cables, (Wires),
7) LCD Screen Assembly,
8) LCD Module Cover.

Primer:
An LCD screen does not produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.
(CCFL = Cold Cathode Fluorescent Lamp. Similar to Fluorescent lighting used in homes, and businesses)

The Backlight for the Gateway LT21 series of Netbook PC's, is a series of LED lights.

There is no screen Inverter that is replaceable by the consumer.
The repair is to replace the entire LCD Module.

http://support.gateway.com/s/notebook/2009/gateway/lt/lt21/LT21sp4.shtml

To conclude:
If the problem isn't the graphics chipset, (Motherboard replacement), and it isn't the LCD Cable, the problem is the LCD Module.

Left-click on LT21.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (LT21) it may take up to 30 seconds, before the first page comes up.

I have a lt21 series netbook and there is a crack in the screen. i am trying to figure out how to take the netbook apart so i can order a new one.


if the notebook is working then just forget it...keep using it...
if you take it appart then something else may go wrong....it's little tricky to do the job of taking it apart and fixing it back...like a jumble puzzle....

if you still feel it need to be fixed contact a tech shop...
spend few $$$ and get an expert to do it...
all the best
