Removing ASUS CG8350 cd drive


Facing the front of the computer is how you determine the Left side, and Right side.
The Left Side Panel removes.

Two screws to loosen. One towards the Top, on the back edge of the left Side Panel; one towards the Bottom.
(Screws should no remove all the way, unless clip is missing from screw)

There's a Fingerpull formed out of the back edge, of the left Side Panel. Pull back, remove.

There should be plastic clips formed out of the Front Panel, that when depressed, or gently pulled out on; will enable removing Front Panel.

WATCH as it may NOT just be a cover.
The Power On LED light (Asus), plus Power On switch, and Harddrive activity LED light, may be attached to the Front Panel.

This is a different Asus desktop computer case, but allows me to show you the clips I am referring to,

http://pctuning.tyden.cz/hardware/pc-sestavy/22300-asus-rog-tytan-seriova-kraska-za-60-tisic-korun?start=5

Scroll down to the photo of the open computer case.
See the three dark plastic tabs on the Front Panel?
One towards the Top, one in the Middle, and one towards the Bottom.

For this type the clips are gently eased out. (They are PLASTIC)

I could be wrong, but I imagine the blue round looking 'knobs', on the side where the optical drive bay is; turn to the Left to remove.
I think the blue round part is a screw head.

Could be wrong. May be they are just gently pulled out on, to release the optical drive. (CD/DVD drive)

Power unplugged to computer.

Asus laptop?

What is the model number Alex? It's on the bottom of the laptop.
Post back in a Comment.

From your brief 'diagnosis', suggests there is a problem with the Video Cable.

1) Either loose at the motherboard, or loose at the screen Inverter,
(IF USED), or loose at the back of the LCD screen.

And/Or;

2) Video Cable is damaged. Stretched/Broken wire inside.

Suggestion would be to PHYSICALLY check the Video Cable's connections.
Visual inspection alone will not do. To -> Ensure the connections are tight, you have to physically try to plug them in tighter.

Do not, of course know what laptop we are talking about here.
(And only presume we are talking about a laptop; and an Asus one at that, because of the problem heading)

The Video Cable plugs into the motherboard, either in an area under the Keyboard; or under the Switch Cover.
(It can also plug into the bottom edge of the motherboard)

Believe easiest way to start off here..........

The Switch Cover is a thin strip of plastic, above the Keyboard; and under the Display Assembly.
Usually has the Power On button in it, indicator LED lights; and speakers. (IF option)

Later designs of laptops did away with using a Switch Cover, and went to just having it as part of the Palm Rest Cover, itself.

Further designs of laptops, also have the Power On button in the side of a Hinge. Usually the Right one.

Moving on........

From the motherboard, the Video Cable then typically routes by the Left Hinge.
Then it goes up into the Display Assembly.

IF a screen Inverter is used, one small cable comes off the Video Cable; and connects to one side of the screen Inverter.
The rest of the Video Cable goes on to connect to the back of the LCD screen.

A screen Inverter is used for CCFL backlighting.
(Cold Cathode Fluorescent Lamp)
GENERALLY, a screen Inverter is not used for LED backlighting.
(Light Emitting Diode)

If no screen Inverter is used, the Video Cable goes on to connect to the back of the LCD screen.
May be a small cable from it to the LED backlights.

From normal repeated opening, and closing of a laptop, the Video Cable may become pinched, and/or pulled on.
(Goes by the Left Hinge)
This can cause loose connections, as described above; and/or cause damage to the Video Cable.
(As described above)

If connections are found to be tight, then Video Cable is removed, and checked for Continuity.

A continuity test is performed with a multimeter, set to OHM's. (1K)
Each wire in the Video Cable is checked for continuity.

(In a continuity test, the multimeter sends electricity through the wire. Positive (Red) probe lead of multimeter to one end of wire, Negative (Black) probe lead to other end of wire.

It isn't the amount of the Resistance you are looking for, so much; it is JUST to see if you get a reading at all.
No reading on multimeter suggests there is a broken wire.

Also an assistant should be used, to gently wiggle the Video Cable; to see if you get an intermittent reading.
If so, this also suggests a broken wire.

You can take the Video Cable down to the nearest computer repair shop, and have the resident tech check it for a couple of bucks.
(If they do not know how to perform this simple test, GET OUTTA THERE. They are parts changers, and not tech's)

OR,
You may opt to simply replace the Video Cable.
Costs usually ranges from $4 to $12.
Have seen examples though, that may range $35.

That's about it for me until I have the model number.

NOT stating I can guide you step by step in these procedures, because it is an Asus.
Thank them for that. They do NOT like to release any info, such as a Service Manual, to the general public.

This antiquated type of thinking could run them out of business, IMHO.

HOWEVER, with your patience, and both of us conversing back, and forth in Comments; I have great expectations that I CAN guide you step by step.

Cracked screen on a aspire1094z notebook and my external display works only in safe mode


Off hand I suggest you disconnect the Video Cable.

May be mistaken, but I think there is enough damage to the LCD screen, that it is causing only Safe Mode to be used.

Of course it does depend on how the LCD screen was cracked.
Dropped the laptop while it was on? Going to be Harddrive damage, and possibly further damage through the laptop.

Let's start by disconnecting the Video Cable connection, at the motherboard side. Then see if the external monitor works, and in normal mode.

I don't find an Acer Aspire 1094z, but I do find an Acer Aspire 3050-1094.
Acer - Manufacturer
Aspire - Model Series Name
3050 - Model Series Number
1094 - Model Number

If this is incorrect state back in a Comment.

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Go to the 'paragraph' that starts with Aspire 1200. (1200 in Blue)
Drop down to the third line (2930), scroll across; click on the blue - 3050.

[Ignore if you are aware;
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 (3050) it may take up to 30 seconds, before the first page comes up.

When I refer to a page number, it will be for the Adobe Reader page number box at the Top, to the right of the Down Arrow.

The Zoom In icon ( + ) at the Top increases the view size, when you click on it.
The Zoom Out icon ( - ) decreases the view size.

IF this applies;
Click on the icon at the Top/Left corner. Toggle Slider.
There will be two square icons.
Show Thumbnails on the Left, Show Document Outline on the Right.
Click on Show Document Outline to see the Bookmarks menu ]

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Laptop closed, normal position except the Back is facing you.
There are two screws to remove, in order to remove the
Keyboard Cover.
Bottom of Page 67, top of Page 68.

Philips head screw, one on EACH side.
They are in the black plastic of the laptop, and next to the silver 'lid'.
(Display Cover = 'Lid')

Turn the laptop around, front facing you; open the laptop.

The Keyboard Cover is the strip of plastic above the Keyboard.
The Hinge Covers are an integral part of this cover.

The Microphone Cable is attached to the Launch Board, and the Launch Board is attached to the bottom of the Keyboard Cover.

For this reason suggest go slow, so you do not damage the cable (Wires); when removing Keyboard Cover.
Once the cover is lifted off, disconnect the Microphone Cable from the Launch Board.

This is an example of the Keyboard Cover removed,

http://www.cdsparts.com/p-379-new-acer-aspire-3050-3680-5050-5570-5570z-5580-middle-keyboard-cover.aspx

Suggest come to the Right side of the cover, and ease it up a little, by inserting a thick guitar pick; into the parting line.
(Where the Keyboard Cover meets the Bottom Cover)

Insert how far? About 1/4th Inch, or half the length of your little finger's thumbnail.

Ease that end up a little, so that you can get a fingertip underneath, then using fingers of both hands; ease up on the top, and bottom side of the cover; as you head towards the Left side.

(Sorry about the run-on sentence)

The cover may just pop off as you start, or you may have to carefully go along, and ease up on it all the way.

To the Left by the left Hinge, you will see motherboard side of the Video Cable.
White piece of Mylar plastic tab to gently pull up on, and this unplugs the Video Cable from the motherboard.

A look at the motherboard side connection of the Video Cable, in a pictorial guide,

http://forum.notebookreview.com/acer/352528-aspire-3050-upgrade-sempron-turion-x2-tl-50-a.html#post4515287

Scroll down to about half page, look at the photo under the heading -
h. remove the long cover, and remove the two screws on the keyboard.

See what looks to be a white piece of tape, over by the left Hinge?
That's the motherboard connection side of the Video Cable, and the white pull tab.

Also details how to replace the LCD screen.
If you wish to do this, I would appreciate a Comment back, so I can give you some tips, and possible guidance if you wish it.

Unplug it. Attach the Microphone Cable again, but leave the Keyboard Cover loose.
(You can't reinstall the cover, because the unplugged Video Cable is in the way )

Reinstall the Battery.
Plug the AC adapter into the laptop, THEN plug the AC adapter into power.
Turn the laptop on.
Any change?

White screen on laptop


Long read ahead Naveen.

Check to see if the problem is the;

A) Graphics chipset,

Or;
B) Video Cable,

http://www.ebay.com/itm/Compaq-Presario-1700-Laptop-LCD-Ribbon-Cable-251352-001-/310601465049?pt=LH_DefaultDomain_0&hash=item48514a3cd9

Or;
C) Screen Inverter,

http://www.ebay.com/itm/Compaq-Presario-1700-LCD-Inverter-KUBNKM011A-/280971500392?pt=US_Laptop_Screens_LCD_Panels&hash=item416b34db68

Or;
LCD screen,

http://www.ebay.com/itm/Compaq-Presario-1700-Laptop-14-1-Inch-Screen-251352-001-/310601464998?pt=US_Laptop_Screens_LCD_Panels&hash=item48514a3ca6

(Not advertising, but on another note; you can buy the whole laptop for $50 USD,

http://www.ebay.com/itm/Compaq-Presario-1700-14-1-Laptop-Pentium-lll-1GHz-256MB-CD-RW-DVD-Rom-20GB-HDD-/390534574226?pt=Laptops_Nov05&hash=item5aedacb092 )

A) Graphics chipset:

Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the back of the laptop.
This is an example of a VGA connector (port), and VGA cable,

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

Scroll down a little for VGA cable example.
You can use a CRT type monitor (Looks like a small TV), or a flat LCD screen monitor of it has a VGA cable.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not:

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

Press, and hold the Fn key down, and at the same time tap once on the F3 key. The F3 key is the Display Toggle-Over key.
Still no?
Hold the Fn key down again, tap once more on the F3 key.

A good display on the external VGA monitor means the graphics chipset is OK.
A white screen on the external VGA monitor, means a problem with the graphics chipset. More than likely the Mounting to motherboard, of the graphics chipset. (BGA surface mount)
If this is the problem post back in a Comment.

A good display on the external VGA monitor, means the problem is the Video Cable; or inside the Display Assembly.
(Screen Inverter or LCD screen)

B) Video Cable:

The Video Cable plugs into the motherboard, in an area under the LED Button Bezel, and right next to the Left HINGE.

[LED Button Bezel is the strip of plastic below the LCD screen, and above the Keyboard. Has LED indicator lights in it, etc ]

It then leads up into the Display Assembly, where a small separate cable connects to one side of the screen Inverter, and the rest of the cable connects to the Back of the LCD screen.

Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pinched.
This allows it to be pulled on, and/or damaged.
(Stretched/broken wires)

ALL power removed, AC adapter (Charger), and Battery; the connections for the Video Cable should be checked.
Motherboard side, screen Inverter connection, and LCD screen side.

Motherboard side connection:
1) Remove the LED Button Bezel.

Two screws (Philips) are removed from the bottom of the laptop, and the LED Button Bezel is CAREFULLY pried up, and off.

Details are in Page 91 in the Service Manual, which I will include at the last of this solution.
I will refer to the page number from now on, for the specific component removal.

2) Remove the Keyboard. Page 93.

I state remove, but do NOT unplug the Keyboard Cable from motherboard connector. Just unfasten the Keyboard, roll LCD screen side towards you, and lay upside down on the Palm Rest Cover.

You MUST physically check the connection for tightness. Try to plug it in tighter.

LCD screen side connection:

Disassembly of the Display Assembly, is not shown in the Service Manual. (At least I couldn't find it)
REMOVAL of Display Assembly is.
So I will guide you step by step. I do not believe the Display Assembly has to be removed, in order to remove the Display Bezel.

The plastic frame in front of the LCD screen is the Display Bezel.
Looks like this removed,

http://www.ebay.com/itm/COMPAQ-PRESARIO-1700-14-1-LCD-FRONT-COVER-BEZEL-/320720203233?pt=US_Laptop_Screens_LCD_Panels&hash=item4aac69ede1

From what I can see, there are four Philips head screws to remove, from the Display Bezel.
There is a Screw Cover at the Top Left, and Top Right to remove.
The is a Screw Cover at the Bottom Left, and Bottom Right to remove also.

The Screw Covers are made of synthetic rubber, or plastic.
I use a computer pick, and lift up at the base of the Screw Cover, where it meets the Display Bezel.

The Screw Covers are held in place by a type of rubber cement.
If you are careful you may be able to reuse them. If they don't stick again, apply a TINY dab of rubber cement with a toothpick.
I LIGHTLY stick them to the Display Bezel for safekeeping.

Remove the 4 Philips head screws. (No.1 Philips screwdriver, or No.1 Jewelers Philips screwdriver)

The Display Bezel has TABS going around the exterior perimeter, of the inside edges.
The Display Cover has matching LATCHES that the Tabs snap into.

I suggest cut a piece of thick construction paper, to JUST FIT the inside edges of the Display Bezel, and lay on LCD screen.
(Display Assembly laid as far back as possible)
This will protect the LCD screen from your fingernails.

The bezel is flexible. Come to the inside edge (LCD screen side), of the right side of the Display Bezel.
Lift the edge up with a fingernail, until you can slide a fingertip underneath.
Can't get in? Move over. You are at a Tab/Latch.

Bezel lifted up with one fingertip slid under, move over with the other hand, and slide a fingertip under. Flex the bezel up a little, and move towards the Top.
By now you should hear a Tab/Latch snap loose.
Sounds like you are breaking something.

(Do use CARE! The bezel can be broken, but not if you are gentle, and go slow)
Keep popping the Tabs/Latches loose, going around the Top, then Left side. By the time you come around the Left side, the entire Display Bezel should pop loose.

(At the TOP. You may have to slide the Latch over to the open side, to get the slot in the Display Bezel to clear, if a Latch is used)

Not your laptop, and uses more screws. Just a basic 'hands-on' guide I thought may help,

How do Iopen the case of an HPvs17x monitor?


The Capacitors on the power board are usually the reason for failure of an LCD. If you open the HP VS17 ( I can provide an exhaustive step by step If I have to) remove the five screws for the power board ( larger of the two boards) and look for an area where there are 4 caps (see pic). Look for exploded, popped up, bulging, or leaking caps and replace with the same or slightly higher tolerances. The one I replaced last night were (2x )1000uf25-50volt and (2x) 470uf25-50volt. Check the rest of the board for similar issues and replace as needed.

Gateway CX2620 Swivel Screen Laptop


This is the worst solution I've ever heard. This guy is trying to steer you wrong I'm pretty sure. There is zero point in removing all the screws from under the batter/ zero point to removing the area around the power button. Absolute BS. The only part to remove is the part just above the top of the keyboard (silver strip with some black). Then by removing that you can pry the swivel black plastic cover off. Whatever you do.. do not follow Scott's writeup here. I'm telling you. It's sad it's stayed up so long.. so had to warn.

It is possible that you switched off the internal video display, enabling the external adapter. If this is the case, you should be able to plug in an external monitor, get your display back, and change monitors back to the internal one via software (display properties).
