Dell Latitude disassembly – LCD cover

I was asked by a friend to replace a lid cover to his Dell Latitude D600 notebook. In my previous post I I covered removing the keyboard and hinge cover. This was the first step in removing the lid cover. His was a bit scratched and the hinges were in poor shape just barely hanging on. Also the locking latch was not lined up correctly so it wasn’t staying shut. The tools you’ll need are the same as before. A small Phillips and flathead screwdriver are essential.

IMG_3524

Here we have the left hand hinge which looks in pretty sorry state. It was very loose and there was space between the hinge in the case. This wasn’t going to last much longer.

IMG_3526

Here’s our Dell with the keyboard and hinge cover removed.

 

IMG_3527

First thing I did was disconnect the LCD display connector from the board.

IMG_3528

It has a small ground strap and a wire connected to the LCD.

IMG_3529

First I unscrewed the ground strap and then disconnected it. It has small handle to aid in pull.

IMG_3531

Now I move on to the hinges. The left hand side has two screws and the other has one.

IMG_3532

After the screws are removed it should lift right out of place.

IMG_3544

Now I’m removing the frame around LCD display. In this case I’m just replacing the lid cover. This would a good reference if your replacing the actual LCD screen too. There are 4 screws along the top edge and 2 in the bottom corner.

IMG_3547

 

After the screws are removed you can then begin gently prying the lid cover apart. I used a small flathead screwdriver. B gently when using this as you could damage the the plastic casing. They do make plastic tools to do this which I do have on order.

IMG_3548

I now have the frame off.

IMG_3550

Remove the screws holding the LCD display in place.

IMG_3555

Lift and remove display. It’s that simple. To assemble just go in reverse order. Here I’m replacing the lid so I just lifted it out the old one and into the new one. I reassembled it. It was easier than I thought it would be. This took me about 30 minute or so. After I put it together and rebooted. It worked great. Thanks for coming by

Dell Latitude D600 keyboard removal

Keyboards on laptops take a lot of abuse. Not only from constant use from spills, IMG_3510dirt, pet hair(and human) and keys popping off. Keyboard replacement is a common repair. On a PC it’s easy to replace. Go to your local computer store. Pick up a new one and come home and plug it in. On a laptop it’s not as simple but still easy if your a littler mechanically inclined. Here is how I took apart a Dell Latitude D600 keyboard. They are not all the same but I thing it would be a good example. All that you may need is a small Phillips screwdriver, small flat head screwdriver and a delicate touch.

IMG_3513

First in this case you’ll have to remove the center plastic cover just above the keyboard. You lie the screen flat. In this case Dell provide a small notch on one side. Insert your small screwdriver there and gently start prying it apart. If you using a normal steel screwdriver use care as you can easily gouge break the plastic. There are plastic ones available I’ve found on Ebay.

IMG_3514

This piece was held in by plastic hooks and snaps in place. Gently pull and pry the piece out. This piece was getting replaced anyway but still I tried to be careful not to damage anything else.

IMG_3518

This Dell had two Phillips screws along the top edge holding the keyboard in place. I removed those.

IMG_3520

I lift up along the back edge of the board. It was held in place along the bottom by some small hooks . Gently wiggling it out I see that a small ribbon is till attached to the base unit.

IMG_3521

IMG_3522

There is a small pull lever that aids in pulling this out. Gently pull this out and your home free.

IMG_3523

This is the keyboard from underneath. You can then replace the board with a newer one. It took me about fifteen minutes to this task. To reassemble you just go in reverse order. It’s not as hard as you might think. As a word of caution. Like any other work you do in a computer be careful of ESD(Electro Static Discharge). You can use a wrist strap or touch any bare metal on the unit or elsewhere around your work area to rid yourself of static. Well good luck and hope this might help someone in the future. Next up will be replacing the lid cover to this same Dell Latitude D600 so stay tuned. Have a great day.

Dell Latitude gets a boost

IMG_3507 A friend of mine asked me to upgrade his memory in his laptop. The patient is a Dell Latitude D600. It had been running with 512mb of RAM with Windows XP Professional. He decided it was time for a boost. I thought I’d show here just how easy it is to upgrade your memory in your laptop.

First step was purchasing the RAM. A common question for computer is what kind of RAM (or memory) do I get. With all the different types of RAM out there and not to mention the technical jargon it can be confusing. I don’t even understand many of them either. My favorite place to purchase RAM is Crucial.com. If you you go to there website they have a memory configurator which helps you out. They have a manual method which you look up your make, model of your machine. They also can scan your computer which takes any guess work out of the equation.

The parts and tools needed:

  • RAM – Crucial Part # CT12864x335, 1GB 200-PIN SODIMM 128MX64 DDR PC2700
  • Small Phillips head screwdriver IMG_3501

Obviously you need the Dell Latitude D600 too. The first thing you’ll have to do is locate where the memory goes. Well you flip over the Dell and it’s located in one of the secret compartments. Dell was nice enough to mark the door with a “M” just to side of it. It’s the 2” x 3” door just off center. It’s just located beneath the COA sticker in the picture . Located on the bottom is a small screw. Now is when you’ll get to use your Phillips screwdriver.


IMG_3503

IMG_3504 Once you open the door you’ll see your two banks of memory cards. Gently pull the two tabs alongside the memory bank.

IMG_3505

Lift up and pull it out.

IMG_3506

Insert your new new memory chip. Don’t worry they are notched so it only goes back in one way. Reassemble in reverse order. After all is put back together I rebooted the computer to make sure everything went well. It now has a healthy 1.25 Gb’s of RAM. This only took about 15 minutes to do. Next up will be removing the keyboard so stay tuned. Thanks for coming by!

What is Free Geek?

You may have noticed in some of my past posts mentioning “Free Geek” . I’ll j0437246attempt explain a little further. In a short and simple explanation they “Help the needy get nerdy” .  Here is the official mission statement from Free Geek of Providence "Free Geek Providence is a non-profit grassroots organization dedicated to addressing the digital divide by providing computer training, redistributing computer technology and providing volunteer opportunities to our community while maintaining relationships with responsible recycling partners."

They are a non-profit group that helps those who perhaps can’t either afford or uninitiated get acquainted with computers. The goal is to provide both training in both building and using a PC. They use free Linux operating system that is both free and relatively simple to use. On top of that they can walk away with a PC they build themselves or earn by volunteering  for the group for certain amount of time.

They do this using donated equipment. Computer stuff that is donated is gone through and tested. If obsolete is it is sent to a local responsible recycler rather than just sent over seas or dumped in the local landfill. Here is a video of what can happen to your old stuff from 60 Minutes. If it is reusable it is used for building units either for the volunteers(to earn) or for sale in a thrift store or online.

This is just a small snippet of what they do for the community. If your in the Rhode Island area and are interested in donating unused computer equipment click here to see more. The Free Geek that started it all can be seen here. Thanks for coming by and have a geeky day. What do you do with your old computer stuff?

Ubuntu Guide from PC World


Here is an excellent guide from PC World on how to install the latest release of Ubuntu Linux. It can still be a little intimidating for the uninitiated to install a Linux software. They have made it a bit simpler. A guide is nice to have.

What to do with old PC's


You can give them to me of course. All kidding aside I do seem to collect old worn out equipment over time and it begins to clutter my work area and garage. What do you do with old stuff. More than likely your local laws and programs may differ. For the most part you can't just throw out PC's with the garbage. They contain some hazardous materials that should be recycled or disposed of properly.

Here in Rhode Island the local recycling facility(aka:The Johnston landfill) which services most of the state hosts a local drop off about once a month. Officially known as Rhode Island Resource Recovery has just posted a new schedule for 2009 with one last drop off this coming Saturday Dec 6. . They are usually held on Saturdays 8am-Noon. It's a fairly simple process. You drive up and they unload your vehicle for you. No need to get out. I'm going this Saturday to clean out some old monitors and some other miscellaneous items. What do you do with your old and tired equipment?

How to fix or recover User Account in XP

I came along this article by Greg Shultz of TechRepublic that goes along with my recent video on User accounts. A very good read if you've had your User Account come up with an error or become corrupt and your unable to recover or log on to your account with all your precious data.

How-to: Buying a computer case

I saw this one and thought of my discussion about building a PC. This is from PCMech which is one of my favorite sites. I was going to do something similar but they beat me to it. Well as the saying goes if you can't beat them, join them so here it goes...

Picnik at Flickr

I use Flickr to share my photo's. Sometimes before editing or touching them up. A nice feature on Flickr is the ability to edit photo's you've already uploading them. The software they use to do this is called Picnik. Here's a demo I shot of it.

How to build a PC - Part 2

Of course your going to need some basic tools. What you need isn't expensive or hard to find. Kits are sold in many places where computers are sold and they are relatively cheap. It's good idea to have this ahead of time before starting your project. The basic tools I've found to be needed are:

  • Screwdriver
  • Phillips head screwdriver- The majority of screws used for PC's are of the this variety. It also maybe handy to have some Torx head screwdrivers too. They aren't too common but, they are out there.
  • Tweezers - These are handy to use with jumpers and the occasional fallen screw.
  • Screw extractor- These are necessary for finding those screws or jumpers the inevitably fall in the nooks and crannies of you case.
  • Magnify glass - A pair of reading glasses will do the trick too. Necessary at times to reading not only the multi-language manuals but also to reading items on motherboard(or expansion cards, jumper settings on a hard drive etc.).
  • Lighting - It's important to have well lit area to work in. A flashlight would be a good idea too.
  • ESD wrist strap - It's important to guard against static(or ESD) while assembling your masterpiece. You can also use an anti-static mat too. These are relatively inexpensive and is cheap insurance against losing that expensive piece of electronicThese are due to static. I will get this more deeply further on.
  • Something to hold the screws- An old egg carton works great for this. You will be dealing many screws, spacers, jumpers etc.. They have a way to fall on the floor out of sight reach just before you need them the most.

These are the basic items I believe you'll need to assemble a PC. It's also a good idea before you begin to gather necessary manuals,instructions, and software related to you hardware before beginning. Just have them in a handy spot because nothings more frustrating than searching franticly for a CD or manual for a piece of hardware you just installed at the last minute. One last thing thing to bring is patience. Nothing worse than getting frustrated or hot headed over this. If you find yourself getting flustered take a break and come back to it. I have found when I get too focused and angered (yes it does happen) that taking a break can clear the mind and allows me to come back refreshed. It's not rocket science to put these together and most anyone with a some degree of mechanical ability can do this I believe. Well that's all for now and thanks for coming by.

Project: How to Build a PC


Lately I've had the itch to build a new personal computer(PC). So lately I've been going over what is needed to build one. I've built a few but it's been awhile since I've done it so I'd thought I'd go over it and share it here. I don't really find it that hard and think it's fun to build something. The hardest part(I believe) is researching and making sure the pieces will match up.

The major considerations you've got to consider are: What is going to be the main purpose of the PC. Is it going to be a gaming machine, home/office use, low budget or a combination of the above. The another consideration is how much your build budget is and how much time you've got to devote to it. Also whether to use new or used parts. Another consideration that may be a no brainer but, to decide whether you can build one.

Well if you've decided to take a project on I've broken down the project into the major components. Internal Hardware,external hardware and software(operating system etc.).

Internal Hardware:
  • Case
  • PSU(or Power Supply Unit)
  • Motherboard(or system board)
  • Memory (or RAM, Random-Access-Memory)
  • Graphics card(or video card)
  • Hard drive
  • Processor(or CPU)
  • Networking(WiFi etc...)
  • Floppy drive
External Hardware:

  • Keyboard
  • Mouse
  • Monitor
  • Speakers
  • Microphone
  • Webcam
Software:

  • Operating System(Windows, Linux etc...)
  • Drivers for hardware(usually included with hardware when purchased)
  • Utility Software(antivirus,antispyware, firewall etc..)
This is the list I came up with. I'm sure I've probably left something out. My goal in the coming weeks and month's to go over each one of these more in depth as I go along. I'll share my research and thoughts on each subject and perhaps help someone else along the way. Thanks for coming by and I hope you'll return.

PC Basics: Windows XP - User Accounts

Who are you?

Imagine when you left for work and asked some stranger who just happened to be walking or driving by if you could watch your home for you. You just let him in and say make yourself at home I'll be back in about eight hours or so. If they don't clear out your house how do you know what they would get into? Of course no sane person would probably do this. I was just dramatizing what essentially happens when you let someone else use your computer without any controls. What I'd like to show you is how Windows XP can give you some control when you let someone else use your computer. Think about all the stuff you store on your computer. It can be personal, financial data, private photos, and more. You wouldn't let a stranger in your house would you while your not home? Well it's almost the same thing if you don't control who can use your computer. Things I'll go over is the benefits of this, how-to create user accounts and explain the differences between them.

Benefits

First I'll try and cover some of the benefits of creating different user accounts. One thing is Privacy. If you keep sensitive information that you would like to share with others this will help. Also it would prevent others from finding what websites you visit. Customizing settings to your preference. If you'd like something other than a Shrek wallpaper adorning your desktop background and 20 icons for kids games. Not to mention stuff like your bookmarks, personal photo's etc. Security wise it'll prevent others from snooping in your finances and other sensitive personal information. It also gives you control when you do decide to let some one else use your PC. Like wondering what websites your teenager or your untech savvy brother-in-law who might go wondering around bikini sites too much when your not looking.

How-to create user accounts

First of all you need to be logged into your administrator account.If you only have one account. Windows sets the the default account to administrator if your unsure. Sure sounds important doesn't it? Assuming your their here we go.


Figure 1. Click on start and go to Control Panel

1. Click on your Start button on your bottom left hand corner and go to Control Panel and click on that.


Figure 2. Click on User Accounts icon


That will open another window and you look for User Accounts icon and you click on that.


Figure 3. Pick a Task


2. In the next window you'll be given a choice of:
  • Change an account
  • Create a new account
  • Change my picture(your picture that will show on the Welcome screen on first boot)
3. We select Create an account

4. You will now enter an account name and click on Next.

5. Next you'll be asked if you want it to be an Administrators account or a Limited account. Then you click Create Account and your done.


What the heck is...


In the last section you may have asked yourself what the heck is the difference between Administrator and Limited accounts. I'll attempt to explain the differences between the two plus the Guest account.

As the Administrator you are numero uno , the man behind the curtain, leader of the free world of your computer. Ok maybe a bit of a stretch on the last one. You have pretty much as much control over the computer as Bill Gates will let you have. Change passwords, delete other users(It's wise not tick of the Administrator), install/uninstall programs, install new hardware , you get the picture. I wish it would make coffee too(I'm sure the guys in Redmond are working on it though).


Figure 4. What kind of account should choose?


Limited Accounts are more restricted. They can use the same hardware and software but they can't install either one. They can change their own password and even change the Welcome screen picture. They can also have their own desktop pictures and adjust computer setting to there liking.


Be my Guest


Guest account is basic like a Limited account but just not setup for any one person. It's good if you have many different people using your PC. To make a guest account on your computer you:
1. Click on Start, then Control Panel, and click User Accounts icon.


2. In the User Accounts dialog Box look in the lower right hand corner click on User Accounts.


3. You can now turn on or off the Guest account.


4. When your done click on the "X" button close out the window.


Fine Tuning

If you click on any of the users in the User Account Window you can change options. Things you can do are:


Figure 5. Make adjustment's here

1. . Change the name - This changes the name of the account displayed on the Welcome screen and top of the start up menu.


2.Create a password - You can set or reset your password from here. You can even choose to have none at all.


3. Change the picture - This changes the picture displayed on the Windows log on screen and start menu. You can choose from any Welcome screen. You can use picture types like GIF,BMP,JPG or PNG. Size of the picture doesn't matter as Windows will automatically resize the picture to fit.


4. Change account type - You can change from administrator to Limited accounts and back again.

Don't worry about deleting yourself, Windows protect itself like HAL from 2001 Space Odyssey. It will always make sure that there is always one Administrator.

We've only just begun

This is only just the beginning of learning how to use Windows XP. Being able manage your accounts is one of the more essential ingredients on managing your computer. We covered the benefits of managing your user accounts. What the different types of accounts are and their functions and how to create, delete and manage them. Like I said you wouldn't let a stranger in your house alone, you should try and manage your PC in a similar fashion. Good luck and happy computing!
