Does anyone have a link for a video of how to open and replace the thermal paste and reseat the heatsink on a Gateway NV79 laptop


Disassembly? Same as the NV78 Series,

http://www.insidemylaptop.com/disassemble-gateway-nv7802u-laptop/

The Ram Memory is on the bottom of the motherboard.
So is the Processor. (CPU)

You have to disassemble from the Keyboard down, and remove the Motherboard.

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.
2) Work on a table. Do Not work on a bed, couch, or directly on a carpet floor. HIGH areas of -> Static electricity.

Suggest lay a soft Static free cloth on the table you're working on.
Helps prevent scratching the laptop, and the table.
Laptop closed, turn it over, lay it bottom side up on the table.

3) Don your ESD wrist strap.
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Wear an ESD wrist strap, and have it's alligator clip attached to a good ground source, and your laptop is safe.
Don't wear an ESD wrist strap, and you can use your motherboard for a Frisbee. (Processor for a neck fob, ram memory for Christmas decorations)

Average cost is around $3 to $6. Here is but one example,

http://www.radioshack.com/product/index.jsp?productId=2103245

4) Remove the Harddrive Compartment Cover, and Memory Compartment Cover.

A) Remove the Ram Memory.
Ease the Spring Clips out a little bit to unlock the Ram Memory module/s.
The Ram Memory module will slightly spring up at an angle.

REMOVE ram memory module AT that angle.
If you lift straight up you will damage the contact pins in the Ram Memory slot.

[To reinstall, Ram Memory module goes back in at THAT angle. Once assured it is seated well in the Ram Memory slot; push it down to lock it in the spring clips ]

B) Remove the Harddrive.
The Harddrive is inside a metal Harddrive Caddy. A sheet metal enclosure. Remove the Harddrive with the Harddrive Caddy.

Remove any screws holding the Harddrive Caddy in, grasp the Mylar strip, pull the Harddrive towards the outside of the laptop, and unplug it. Lift up at an angle, lifting on Mylar strip side, and remove.

5) Remove the single Philips head screw holding the DVD drive in place, remove the DVD drive.
(No.1 Philips screwdriver, or equivalent Jewelers screwdriver)

6) Remove the 3 Philips head screws down in the Battery Compartment.
Turn the laptop over to it's normal position, open it up.
Remove the Keyboard Cover
(Gateway terminology. In pictorial disassembly it is called the LED Board Cover)

When removing, BE AWARE that there is a Multimedia Cable still attached to the Multimedia Board.
(Multimedia Board is attached to the bottom of the Keyboard Cover)

Gently pop the Keyboard Cover loose. I DO NOT recommend using a metal tool! Use a thick guitar pick to start, ease off with fingertips; OR use a Spudger Tool,

http://www.amazon.com/Techni-Tool-Spudger-Alignment-Tool-Black/dp/B000PDNPYK

http://www.wisegeek.com/what-is-a-spudger.htm

The Multimedia Board in the Keyboard Cover, has a cable just like a Keyboard Cable. It is an FFC. Flat Flex Cable.
One example,

http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg

As you can see, there is NO plug connector on the end of the cable.
The FFC slides into a motherboard connector, that is a style of ZIF connector.
Zero Insertion Force.
Slides into the BODY of the motherboard connector, and is locked in place by a Wedge design. The Locking Bar wedges against it.

The Multimedia Board Cable's flat bar terminal strips, line up with contact pins on the motherboard connector.
The Multimedia Board Cable MUST go back in the same position, as it was when originally installed.
Even if it's twisted, flopped over, or going to Hawaii for vacation(?).

For this reason, you may wish to make a mark on one side of the cable, and a matching mark on the same side of the motherboard's connector. (Sharpee?)
Do the same for the Keyboard Cable, and all flat flex cables if you wish.

IF, the motherboard connector is broken for the Multimedia Board Cable, or Keyboard Cable, or Touchpad Cable, or any flat flex cable; your are looking at MOTHERBOARD REPLACEMENT, and why I am being so detailed.

The Multimedia Board Cable's motherboard connector, is supposed to be what I deem, the Flip-Up style.
This is a better illustration of how to open that connector,

Flip-Up style:
Closed/Locked,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-13.jpg

Open/Unlocked,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-14.jpg

Use the Mylar tape on the Multimedia Board Cable, to remove it from the motherboard connector after unlocked.
Lay the Keyboard Cover aside.

7) Remove the Keyboard:
The Keyboard has TABS on your side. They slide under the Palm Rest Cover. Lift the Keyboard at a slight angle on the LCD screen side, slide it towards the LCD screen JUST a little.

Lift the Keyboard on the LCD screen side, roll it over towards you, lay on the Palm Rest Cover.
Disconnect the Keyboard Cable from the motherboard connector.

Shows it to be what I deem the Sliding style.
Here is another example of that style of motherboard connector, only in more detail,

Sliding type:
Closed/Locked,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L675D-L670D/big-body/dismantle-laptop-10.jpg

Open/Unlocked,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L675D-L670D/big-body/dismantle-laptop-11.jpg

As you can see, in the Locked position all you see are two 'Tabs' of the sliding Locking Bar.
Use your Thumbnails to GENTLY ease it open.
Using a metal tool is DU-MB.
One slip, and you break the motherboard connector, or stab the motherboard.
The Locking Bar only moves about 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <-

8) Close the laptop, turn it over. Remove the Wireless Module.
There are two Wireless Antenna wires. One Black, one White.
Make a note as to WHICH terminals on the Wireless Module, that they go to. [Black to Main {1} White to Aux {2} ]
The Wireless Antenna wire's connector clip, slides off to remove.

Remove the Philips head screw which holds the Wireless Module in place, remove the Wireless Module. Makes it MUCH easier to access the Wireless Antenna wires.

The Wireless Antenna wires STAY with the Display Assembly.
They go up into the Display Assembly, and are connected to the Wireless Antenna.

The Wireless Antenna wires are threaded, ('fished') up through the cavity hole in the laptop; and laid to the right side out of the way.
(Gently pull one wire from the top with one hand, while easing the wire up from the bottom with the other hand)

The Wireless Antenna wires go through CHANNELS and LATCHES.
They MUST be reinstalled in the same routing as they were originally! Failure to do so, will NOT let the laptop close properly when reassembling, and MAY cause damage to the wires! (Pinched/Broken)
You can lay the laptop on it's side to ease facilitation of removal.
Fish the Wireless Antenna wires up, and out.

Need to know where antenna card is located on my p25 toshiba laptop


The Wireless Module is located on the Bottom of the laptop,

http://www.irisvista.com/tech/laptops/ToshibaP25/disassembly/big/Toshiba_SatelliteP25_03.jpg

The top card to the left. (With the red arrow)

White Wireless Antenna wire, and a Black Wireless Antenna wire.
You can see which terminal the White wire connects to. Leaves the other terminal for the Black wire.

Beginning page of pictorial disassembly guide, (Page 1),

http://www.irisvista.com/tech/laptops/ToshibaP25/SatelliteP25_1.htm

Page1::Page2::Page3::Find another model, is in White, and on the Top of each page, and Bottom of each page.

The Wireless Antenna wires attach to the Wireless Module,

http://www.ebay.com/itm/WIFI-WIRELESS-PA3299U-1MPC-Card-for-17-Laptop-Toshiba-Satellite-P25-/170900245815?pt=LH_DefaultDomain_0&hash=item27ca72cd37

Looks to me the White wire to MAIN, and the Black wire to AUX.

The Wireless Antenna wires then thread up through a cavity (Hole), in the laptop body, and go through/by the Right Hinge.

From there they go into the Display Assembly, and connect to the Wireless Antenna,

http://www.irisvista.com/tech/laptops/ToshibaP25/satP25_LCD.htm

http://www.ebay.com/itm/Toshiba-P25-Satellite-Laptop-WiFi-ANTENNA-K000006070-/220547282983

Scroll down, read the description.

The Wireless Antenna wires route through CHANNELS, and LATCHES.
The Wireless Antenna wires MUST go back in the SAME routing they were originally.

Failure to do will cause the laptop to not go back together correctly, and can cause damage to the Wireless Antenna Cable. (Wires)

What is Causing my top case cover to hang up and not come off?????


http://www.irisvista.com/tech/laptops/toshiba-satellite-a205/laptop-disassembly-1.htm

Click on the photo in Step 4.

What screw did you miss?

Display Assembly is removed in order to remove the Upper Cover.

http://www.irisvista.com/tech/laptops/toshiba-satellite-a205/laptop-disassembly-3.htm

Step 12.

The Upper Cover has TABS going around the perimeter, on the inside edges.
These Tabs snap into matching LATCHES on the Base Enclosure.
(OK. Toshiba? Bottom Cover)

Just like the article, I like to start with a thick guitar pick, to get an edge to come up. I start at the Right/Middle, but it's really a personal preference thing.

After the Upper Cover edge is raised a little, I then use my fingertips. You would find a Spudger Tool though, makes life a whole lot easier doing this,

http://www.amazon.com/Techni-Tool-Spudger-Alignment-Tool-Black/dp/B000PDNPYK/ref=sr_1_7?ie=UTF8&qid=1359090938&sr=8-7&keywords=spudger+tool

(It isn't made of metal)

Can't get the guitar pick, or spudger tool in? Move over a little. You are at a Tab/Latch.

Screen on laptop is distorted halfway


A) Video Cable connections are loose:
Connection at the motherboard, and the connection at the back of the LCD screen, in the Display Assembly.

Both need to be checked.

[For Toshiba the Video Cable is termed LVDS Cable.

Low-Voltage Differential Signaling Cable. I will just keep referring to it as the Video Cable ]

B) Video Cable is damaged:
Observe the sheath at the motherboard side of the Video Cable?
Is there obvious signs of damage to the sheath of the cable?

If so, there may also be damage to the tiny, thin wires inside the sheath, of the Video Cable.

Due to the routing of the Video Cable under the left Hinge, the Video Cable may be pulled on. This can create a bad connection.

Due to the above also, the Video Cable's sheath may be damaged, and the wires inside.

A view of the Video Cable by itself,

http://www.batterystyle.com/toshiba-satellite-a205-s5880-cable-p-484063.html

If the Video Cable checks out to be OK, the next item is the screen Inverter.
To test a screen Inverter you need a sensitive multimeter. This usually means expensive. { Or use a known to be good, compatible screen Inverter } Just thought I would state that. Don't want you to completely disassemble your laptop, just to fix a Video Cable, or screen Inverter. {Or LCD screen)

Most consumers decide to just replace the screen Inverter because;
1) If the problem isn't the screen Inverter, it is the LCD screen.
(A LOT of people buy an LCD screen, when all they really needed was a screen Inverter)

An EXPENSIVE part.
(LCD screen? $150 to $400 approximately. Screen Inverter? Usually around $22 to $48 )

2) The ease of access to replace.

As stated, if the problem isn't the screen Inverter, then it is the LCD screen.


1) With ALL power removed, AC adapter (Charger), and Battery, remove the Keyboard Bezel, and the Keyboard.

This is the motherboard connection side.

Display Assembly removed with Video Cable.
Now remove the Display Bezel, and LCD screen assembly, to access the Video Cable connection to the back of the LCD screen.


{NOTE*
The screen Inverter is mounted at the bottom of the LCD screen, and behind the Display Bezel }

This shows the Video Cable, and it's connection at the motherboard side,

http://www.irisvista.com/tech/laptops/toshiba-satellite-a205/laptop-disassembly-2.htm

Scroll down, click on the photo in Step 9.
The Video Cable is the cable to the upper Left side. Has one Red arrow pointing to the left.
The photo in Step 10 shows the Video Cable disconnected from the motherboard.

(This is Page 2 of a disassembly guide. Pages 1 through 4 are available above, and below. Page1::Page2::Page3::Page4::Find another model,
in white.
Just thought I would state that. Don't want you to completely disassemble your laptop, just to fix a Video Cable, or screen Inverter, or LCD screen) )

2) LCD screen side:

http://www.irisvista.com/tech/laptops/toshiba-satellite-a215/disassemble-display-panel-4.htm

http://www.insidemylaptop.com/remove-lcd-screen-from-toshiba-laptop/

All three links above will help you with checking the connections, or removing the cable to perform a continuity check. (Test)

Also with accessing the screen Inverter, and LCD screen.

How do i remove the cd/dvd drive for my acer3003lc so that a can replace it


You can use the Toshiba Satellite 5205 guide for removing and replacing the DVD/CD-ROM drive or the keyboard. On this model you have to remove the keyboard in order to remove and replace the DVD/CD-ROM drive because the optical drive securing screw is located under the keyboard. Always start laptop disassembly with removing the battery or you can damage the system board if you accidentally touch it with a screwdriver and shorten traces. Removing the keyboard strip is not very difficult, use your fingers to release the plastic latches. If you want to replace the keyboard, do not forget to unlock the connector on the system boar before you pull the cable.

for the acer 3000
1. At the back of the laptop remove the three screws on the support posts for the screen
2. Open the laptop fully and lift the plastic panel that has the power button.
3. Remove the 2 screws holding the keyboard in place
4. Carefully slide the keyboard towards the monitor and lift.
5. To the left of the keyboard ribbon cable is the screw that's been causing all this grief.
6. Remove, slide out optical drive, reassemble.

How do I replace the keyboard?


next to the F1 key and the windows key (2nd upper key and second to last key) are two screws, usually under some covering. unscrew and lift top edge of the keyboard towards the trackpad to lay face down. Undo the wire ribbon by lifting the grey or brown tabs and remove ribbon and keyboard. Then install the new keyboard by inserting the ribbon on the place. Lock down with the tabs and put the plastic prongs (close to the space bar) into the laptop body first, and then close keyboard onto the final position. screw back in and thats all. nboulikas@gmail.com for any additional questions.
