Where is the backlight resolution located on series 442 e machine laptop

1) Is the Screen resolution set correctly?

Native screen resolution should be set to 1024 x 600.

Right-click on an empty area of your desktop screen.
Go to the bottom of the list, and click on - Properties
The Display Properties window will come up.

Click on the Settings tab.
Down in the middle of the Display Properties window, you will see Screen resolution in blue.

There is a Slider. In WinXP it is an Arrow, with a Green tip on top, and bottom.
Left-click on the Slider, hold the left mouse button down.

Now move your mouse to the Left, to drag the Slider to Less screen Resolution, or to the Right to Increase.

Stop at 1024 x 600 pixels.

Also the Color quality should be set to Highest (32 bit)

Click on the blue down arrow to the right of the Color quality box.
In the list click on Highest (32 bit)

Go below to the Right, and click on Apply.
Now go below to the Left, and click on OK.

If that doesn't cure the problem, the problem is a hardware issue.
Problem will be;
1) Graphics chipset,
OR,
2) Video Cable,
OR,
3) LCD screen

[The Backlight used is LED backlighting. Uses a series of LED's.
Light Emitting Diode.
There is NO screen Inverter ]

A) Is the Screen resolution correct?

B) You may have a problem with the screen Inverter, or Video Cable, or LCD screen.

A short primer if I may;

An LCD screen does not produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the monitor image)

It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL (Or more than one), or a series of LED's
(Light Emitting Diode)

A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.

Average thickness is 2mm. That is a little larger than 1/16th of an Inch, or about the width of this capital letter -> O <-
Average length is almost as long, as the LCD screen is in height.

Not knowing what laptop is in reference here, I cannot tell you whether your laptop uses CCFL/s, or LED's.

A screen Inverter is used to convert the power from the laptop, for the screen Inverter.

Laptops that use a CCFL for a Backlight, also use a screen Inverter.
Laptops that use LED';s for a Backlight, may or may Not use a screen Inverter.

90 PERCENT OF THE TIME, the fault can be attributed to a bad screen Inverter.

Primer over.

What is the laptop manufacturer name, and model number?
The model number is on the bottom of the laptop.

A screen Inverter is used on laptops that use CCFL for Backlighting.
A screen Inverter converts the power (Electricity), from the laptop, for the LCD screen, and Backlight.

Laptops that use a series of LED's for backlighting, do Not use a screen Inverter.

The plastic thin frame in front of the LCD screen, is the Display Bezel. (Toshiba = LCD Bezel)
The screen Inverter is located behind the Display Bezel, and mounted at the bottom of the LCD screen.
(LCD Screen Frame, actually)

Easy to get to; easy to replace.

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-M305/remove-screen-inverter-video-cable-1.htm

How to test a screen Inverter? Requires a Sensitive multimeter.
Read fairly expensive,

http://www.fonerbooks.com/test.htm

Because of this; and the low cost, plus ease of replacing; most home users just opt to replace it.

Know this;
Fluorescent lamps have MERCURY inside. HIGHLY poisonous.
Now couple that with the long thin makeup of the CCFL, and how easy it is to break it.

This is why if the screen Inverter is found to NOT be the problem; I would suggest replacing the LCD screen itself; instead of trying to replace the CCFL, and cause possible Mercury poisoning.

kezler_0007,

I have found in the 8 years of being online, and providing answers/solutions to people's computer problems; that coming across, and trying to explain the answer/solution, is the hardest thing to do.

It appears I have failed you

Let's try again;

1) Perusing the internet, I look at what LCD screens are offered, (Aspire 4315 series of Notebook PC's), and see what backlighting is offered.

I have seen LCD screen examples offered, that seem to be CCFL backlighting.
I DO have to know however, WHAT style of backlighting is used for YOUR laptop.

Do Not want to make a mistake here, because the mistake could cost you five times as much.

You buy a not needed LCD screen, about $100, and only needed a screen Inverter; about $18.

!O_O!?

IF, your laptop states LED backlighting, THEN the only option is to buy the entire LCD screen.
With LED backlighting, the LED backlighting is incorporated into the LCD screen assembly.

There is no simply replace the LED backlighting.

With a laptop that uses CCFL for backlighting, the first thing to do is replace the screen Inverter.
90 PERCENT OF THE TIME the fault is a bad screen Inverter.

Allow me to state the primer over again, now that I have more room;

An LCD screen does Not produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the monitor icon)

Therefore an LCD screen needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them), Or a series of LED's.
(Light Emitting Diode)

When I state series, I mean a LOT of LED's. They are incorporated into the LCD screen assembly.
(You see from the above link that an LCD screen is an assembly)

A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

View the last 8 photos to see what an average CCFL looks like.

Know this also; A CCFL is a Fluorescent bulb.
This means it has MERCURY in it.
VERY dangerous if the bulb breaks!
Mercury is POISON to the human body.

IF, it is determined that the laptop uses CCFL/s for a Backlight, -> AND the CCFL/s are bad, I implore you to have a pro change it/them.
The other option would be to replace the LCD screen.
The CCFL is incorporated into the LCD screen assembly.

HOWEVER, I still go with the screen Inverter is bad.
(IF, the laptop uses CCFL for a Backlight)

Test the screen Inverter before replacing?
IF you have a sensitive multimeter, you can. Otherwise IMHO the choice is to just replace the screen Inverter.

1) Looking at the User Manual right now, and do not see a Hot Key on the Keyboard, that shifts the display.

[ Hot Key is also known as Special Key. The F1 through F12 keys at the top of the keyboard, and also for your model, colored keys on the keyboard ]

It could be the Screen Resolution is messed up. Not set at the correct settings.

Right-click on an empty area of your desktop screen.
At the bottom of the drop down list, click on Properties.

In the Display Properties window click on the Settings tab.

The screen pixel resolution should be set at 1366 X 768,

http://www.screentekinc.com/Asus_EEE_PC_1201HAB--12.1-inch--1366x768-wxga_hd-laptop-lcd-screen.shtml

In the middle of the Display Properties window, you see the blue subheading - Screen resolution

Right under this small subheading is a Slider.
The Pointed 'arrow' with the green tip, and top, slides back, and forth on the 'line'.

It should state 1366 X 768.
If it does not;

A) Left-click on that green tipped Slider. Hold the left mouse button down. Move your mouse, and move the Slider. (Drag)
Move it to the Left to Decrease the screen resolution, or to the Right to Increase the screen resolution.

Can't set it to 1366 X 768? Post back in a Comment.
ALSO, the Color Quality should be set to -
Highest (32 bit)

If not click on the blue down arrow to the right of this box.
In the list left-click on Highest (32 bit)

Now go below to the right, and click on Apply.
After go below to the Left, and click on OK.

Still no joy?
Believe the problem is hardware related.

Could be something as simple (?) as a bad Video Cable.
(Goes from the motherboard, up under the left Hinge, and then up into the Display Assembly)

Could be the screen Inverter.

However the Eee PC 1201HAB is supposed to use an LCD panel, that has qa series of LED's for backlighting.
Newer backlighting that uses a series of LED's for the Backlight, doesn't require a screen Inverter.

There were some LED backlit LCD screen, that DID use a screen Inverter. Mostly the older models of laptops.
This is what makes me think your LCD screen's Backlight, (And LED), may use a screen Inverter,

http://www.batterystyle.com/asus-eee-pc-1201hab-screen-p-168219.html

Scroll down,
"5. Disconnect the power cable and video cable from the Asus EEE PC 1201HAB Lcd panel. The power cable connects the screen's power source, the lcd inverter, to the backlight lamp attached to a side of the panel."

Probably just a generic form, and didn't take in consideration that the Eee PC 1201HAB netbook, uses a series of LED's, as a Backlight.

May not have a screen Inverter.

To explain;
Primer:

An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the window with the computer monitor in it )

It needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.

[ LED = Light Emitting Diode.
CCFL stands for Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

{Average thickness of a CCFL bulb is 2mm. That is a a little larger than 1/16th of an Inch.
The average length is almost as long, as the LCD screen is in height]

A screen Inverter is used to CONVERT the power from the laptop, for the LCD screen, and Backlight.

Do not see any listings for an Asus Eee PC 1201HAB netbook, for a screen Inverter. Believe the LCD screen uses LED's for a Backlight, and does NOT use a screen Inverter.

Which means if the problem is in the Display Assembly, the LCD screen itself will need to be replaced.
The LED backlighting is built-in.

[Hmmmm, I see a trend going on here that I do not care for, and just woke up to it. Have to replace the entire LCD screen, and cannot just replace the Backlight, or screen Inverter? Sounds like Ka-ching $$$$$ for somebody!

A screen Inverter usually averages from $20 to $40+.
A Backlight ( CCFL) usually ranges from $10 to $15.
An average LCD screen can range from $80 to $300+.]

How to know if the problem is in the Display Assembly?
Use a VGA monitor, and connect it to your laptop.

A) Laptop OFF, monitor OFF. Connect a VGA monitor's cable to the VGA port on the laptop.
(Left side rear. This is an example of a VGA Cable, and VGA connector { Port on a computer },

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

You can use an older CRT type of VGA monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable attached.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By default the display should automatically show, on the external VGA monitor.
IF not;

There are at least three display options:
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and hold it down. At the same time tap once on the F8 key.
The F8 key is the Display Toggle-Over key.
(Give it a few seconds. Sometimes it doesn't happen right away)

Still no?
Hold the Fn key down again, and tap once more on the F8 key.

Is the display off to one side on the external VGA monitor?

An LCD screen cannot produce enough light by itself. It needs an additional source of light.
A Backlight is used as the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to the Fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

The LCD screen is a composite of layers, surrounded by a thin metal frame that resembles a picture frame.
To one side of the LCD screen layers, and under the frame is usually where the Backlight is mounted.
[Note* Two Backlights are used in some models]

Replacing a Backlight is more labor intensive than replacing an Inverter.
Due to this, and the cost, the LCD screen itself is replaced as a unit most of the time, when it comes to Backlight replacement.

Example of a replacement LCD screen for the HP G5000 series of Notebook PC's,

https://www.screentekinc.com/HP_G5000_Series--15.4-inch--1280x800-wxga-laptop-lcd-screen.shtml

[Note* Stating HP G5000 is just stating the model series. When buying replacement parts the EXACT Model Number should be used. This information is located on the bottom of the laptop, in a white Service Tag.

When replacing an LCD screen, the model number of the replacement LCD screen should be matched to the existing LCD screen's Model Number.
Inverters and LCD screens are matched together. Make sure you get the correct part]

An Inverter is used to provide power from the laptop to the LCD screen, and to the Backlight.

Note* 90 Percent of the time the problem is a bad Inverter.

Example of an Inverter for an HP G5000 series notebook PC,

http://www.zlectronic.com/product/INVERTER-FOR-HP-DAC-07B035-DAC-09B017-DV5000-G5000.html

The LCD screen, Top Cover, Display Bezel, Inverter, Backlight, and various screws, make up the Display Assembly.
The Display Bezel made of plastic surrounding the LCD screen, and in front of the LCD screen is removable.
Behind it is easy access to the Inverter.

The Inverter is approximately 4 inches long, and the width of a No.1 pencil.
Usually located at the bottom of the LCD screen, and right behind the Bezel.

This article shows replacing an Inverter and LCD screen on a Compaq Presario v2000 series Notebook PC,

http://www.insidemylaptop.com/replace-lcd-screen-inverter-compaq-presario-v2000-laptop/

This pictorial guide is not for the HP G5000 series Notebook PC, but the models are very similar when it comes to Inverter replacement.
The above link is to show you what is involved.

hello

If your original LCD Screen Resolution is more than 1024x768, Please don't use this

this LCD is worth about $100

Brand: LG.PHILIPS
Part Number LP154WX2
Size 15.4-inch Screen (13.1"x8.2")
Resolution WXGA (1280x800)
Surface Matte
Aspect Ratio Standard
Backlight Type CCFL 1-Bulb
Backlight Connector 2 pins Backlight Connector
Video Signal Connector 30 pins Video Connector


hope i served you well

Suggest you replace the Inverter. A Backlight goes out all at once.
90% of the time the Inverter is the hardware part at fault.

[ An LCD screen cannot produce enough light by itself.
A Backlight is used to supply the needed extra lighting.
A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a much smaller scale

An Inverter is used to required power for the LCD screen, and the Backlight.
Boosts power up for the LCD screen, brings it down for the Backlight.

http://support.dell.com/support/edocs/systems/latd600/en/sm/index.htm

Replacing an Inverter is a simple job. Replacing a Backlight is not.
The Backlight is located within the LCD screen assembly.

The metal frame of the LCD screen assembly is removed along the edge where the Backlight is located, to access replacing the Backlight.

In the above list for Service Manual, click on > Display Assembly and Display Latch.

This information shows you where the Inverter is located on a Dell Latitude D620 Notebook PC.
The Latitude D620 is part of the Latitude D600 series of Notebook PC's.

Just one place from a quick search, that sells Inverters for a Latitude D600 series Notebook PC,

http://www.parts-people.com/index.php?action=item&id=2895

MATCH the part number listed that they have, to the part number on your Inverter.
You have to have THE correct Inverter.

If you mean the desktop isn't completely filling the display, you need to be sure the resolution is set correctly. Native resolution for this model is 1500x1050, according to Dell's site. (Native resolution is the one the screen was designed to best work with. Unlike older CRT monitors, some resolution settings don't work well on LCD screens.) You can check and set the resolution through the Windows control panel.

If you mean that the display is dim and hard to make out, but is okay on an external monitor, you probably have a backlight issue. Without the backlight, you can't see what's on the screen even though the display is working. The usual cause of backlight failure is a bad inverter. The inverter is a small circuit board in the display that provides power for the lamp. Replacements are available for most laptops, and changing one is normally not a major job.

If your system won't display anything w/o the external monitor. there's something wrong with the LCD's backlight. you may have to contact your laptop's manufacturer and check if this laptop is still under warranty. you may have to get the lcd replaced.

thanks.
