Replace broken DC power jack on your laptop computer (UPDATED).

OK, I had my kids running around my room and kept tripping on my laptop's power cable. Then DC power jack was damaged. I had to always keep pressing the jack in order to charge my laptop. I reached my limit. I was almost throwing my computer out of my window, but it cost about 


This instructable does not require advanced soldering/desoldering skill. I had never desolder anything before, but was able to somehow desolder the jack.

[UPDATE]
The problem kept coming back. So I did permanent fix using modem port in my latest instructable.

 


Step 1: Initial Diagnostics

You can observe the damaged DC jack on the back of my computer.
The new DC jack shows how it is supposed to be.

Step 2: Materials required

Materials required for this instructable are following.

1) Soldering iron (25W)
2) Multimater (optional)
3) Small screw drivers: 1set
4) Pen
5) Paper
6) New DC jack*
7) Thermal compound (often used for computer)
8) Disposable cups x6
9) Desoldering braid ($5 at RadioShack)
10) Isopropanol (not RNase Free)

  • New DC jack was puchased from DC PowerJacks.net
DC PowerJacks.net
Mine was less than $7. You can google and find cheapest source.

Step 3: Most important key! DOCUMENTATION!

The reason why you need pen and pencil is that you need documentation. I can't emphasize enough this. You will find yourself with extra screws and non-functional laptop if you don't.

Look around and write down schematic diagram of your computer.
You will assign screw numbers and mark them into your figures as you disassemble.

Step 4: Disassemble 1

Remove hard drive, optical drive, battery, and what ever you can remove.
Remove screws and assign screw number.
Place screws into corresponding disposable cup.
Take note where and what type of screws were there.

how to repair broken laptop screen

How to replace a broken laptop screen

A cracked screen can make a laptop unusable. Luckily, you can fix it. Bill Detwiler gives you step-by-step instructions for replacing a broken laptop LCD panel.  


Whether it's cracked or has one too many blown pixels, a broken laptop display can stop you dead in your tracks. But with the right tools, a little technical know-how, and a bit of patience you can replace a damaged LCD

 

Note: In this article and video, I show you how to replace the screen on an Asus UL50V notebook, which has an LED-backlit LCD. Depending on the make and model of your laptop, the internal hardware and specific steps may vary. The general process however, should be the same.

Should you try this fix?

If accidental damage is covered under your laptop's warranty, don't do this fix yourself. Get the laptop repaired under the warranty.
I also suggest you watch my earlier video on what to know before trying to fix a smartphone or tablet. It's not specifically about laptops, but the information is still relevant, and it will help you decided if you should repair the machine yourself or take it to a shop.
Lastly, understand that if you follow the instructions in this video, you do so at your own risk. Neither CNET nor any of its representatives can be held responsible for injury, damage, or loss of data.

Getting a replacement screen and tools

To begin your fix, you'll need a few simple tools and a replacement LCD screen. For tools, I recommend a screwdriver with a variety of small bits, such as a Phillips #00 and a Torx T5. It's also a good idea to have a few thin metal blades or plastic spudgers. These are really handy for removing the trim that surrounds the screen.
As for the replacement LCD, you should be able to buy one either from the laptop manufacturer's authorized parts dealer or a third-party supplier. Depending the screen, they usually cost between $50 and $250 dollars--more if it's a high-end display or you buy an OEM replacement. Regardless, you'll want to buy a new screen that matches your broken one exactly. The only sure way to do this is to remove the broken one.

1. Remove the screen bezel

After disconnecting the power supply and removing the battery, carefully examine the bezel around the screen. You'll need to remove this bezel to access the screws that hold the LCD panel in place.

On this laptop, several rubber cushions hide screws, which hold the bezel in place. I'll need to remove these cushions and the screws that are underneath.
With the hidden screws removed, I used a thin metal blade to pop loose one of the bottom corners and worked my way around the bezel with a plastic spudger.

Note: Your laptop may not have cushions or hidden screws. The bezel may simply snap onto the lid or be held in place with double-side tape. Just, adapt my instructions to fit your specific laptop. Regardless of how you do it, you'll need to completely remove the bezel.

2. Remove the broken LCD panel

With the LCD's mounting brackets exposed, you can remove the screws that secure it to the lid. Then rest the display front-side-down on the case and disconnect its cable.

If your laptop was made before 2010 and has a LCD with fluorescent backlights, it will likely have two cables. But as this is an LED-backlit LCD, it only has one.
Now, locate the manufacturer's label and note the model number. Using this information you should be able to buy an exact match for your broken screen.

3. Install the new LCD panel

Once your new screen arrives, unpack it and make sure it matches the old one.

If the dimensions, mounting brackets, and connector all match, you ready to install the screen. Connect the new panel to the cable, position the panel in the lid, and secure it using the appropriate screws.

4. Test the new LCD panel and reinstall the bezel

Before reattaching the bezel, it's a good idea to test the new panel. Reconnect the battery and power cable and turn the machine on. If the display works, you can reattach the bezel and any external screws and rubber cushions. The repair is now complete.
As fixes go, this one isn't too tough, but it does take a little patience and planning to make sure you get the right replacement screen.

Dell Administrator and BIOS Password Reset on Laptop/PC

Dell Administrator and BIOS Password Reset on Laptop/PC

Forgot administrator password on Dell Inspiron laptop? Lost BIOS password when you want to enter BIOS settings option on Dell computer?
Now let this passage tell you how to reset Dell admin password and how to remove or clear BIOS password on Dell computer.
  1. Dell Admin Password Reset on Windows 7/8 Laptop
  2. Remove BIOS Password on Dell Computer

Question 1: How to Reset Dell Admin Password on Windows 7/8 Laptop

When we forgot Dell administrator password, we could consider it on different perspective. And then you could find appropriate and effective password recovery ways to reset Dell administrator password.
Now we could think that whether it is the only administrator on Dell computer.
  • If not, just use another available administrator to login computer and change or remove forgotten admin password on Control Panel.
  • If it is, try to use password reset disk to recover Windows password firstly. But if you don’t have it, Dell administrator password reset would become a little difficult.

Reset Windows 7/8 Dell Administrator Password without Disk

For Windows 7/8, even though you have no reset disk, Windows password recovery still can be come true.  For example, password hint, PIN code, Microsoft account can be used to remind lost Windows password or login locked Dell laptop. When all these don’t work, you still could try the following ways to reset Windows password without disk after Windows admin password forgot.
1. System Reset Disk
If you've forgotten Windows password, there are several utilities to reset it. One of them is Windows' own System Recovery Disk. As a side note, this password reset trick, which takes just ten minutes to do, is a security hole in Windows 8 and earlier systems, which you can prevent an attacker from hacking into your computer with encryption.
All you need to reset the Windows password with this method is another Windows PC so you can make the System Recovery Disk and burn it to a CD or USB thumb drive. You can create the system recovery CD from the Control Panel > Windows 7 File Recovery.
Basically, you boot into the locked PC with the recovery disk and open up the command prompt, and then replace the Ease of Access Center application (utilman.exe) with another copy of the command prompt (cmd.exe) with administrative privileges. Then you use the "net user" command to type in a new password for the user whose password you want to reset.
Command: net user <user name> <user new password>
2. System Restore
Example: Use System Restore as Recovery Tool in Windows 8
When a change causes your system to act strangely, you can undo that change by performing a system restore operation. Now, you can restore system to early back up point in order to remove admin password.
If Windows will not start, you can use the Recovery Drive to launch System Restore. If Windows does start, you can launch System Restore from within Windows.
To do so, access the System Protection tab and click the System Restore button. In a moment, System Restore will begin an initialization process and you'll then see the introductory screen in the wizard driven interface. After System Restore starts, you'll see the first screen in the wizard driven interface.
When you click Next, you'll see a table showing the most recent restore points. If you select the Show more restore points check box, you will see any older restore points that are still available.
3. Windows password recovery tool
The above two ways are related to Windows system, looking a little difficult for general computer user to do so. Actually, they are not so difficult. But here, I want to share easier Windows password recovery tool for you.
Windows Password Genius or Password Genius is OK. If you get Password Genius, it would not only reset Windows forgotten password, but also recover Office files and archives password.
3-1 Download and install it on another computer.
3-2 Run it and choose Remove Windows administrator and user passwords. Now just get into it and burn a password reset disk.
remove windows administrator and user password
3-3 Insert bootable USB into computer and choose it to create password reset disk by clicking “Begin burning” button.
When it completes burning a reset disk, exit and plug it into locked Dell computer to set computer boot from USB drive.
burn windows password reset disk
3-4 After you see Windows Password Genius runs, select Windows system and admin account. And then click “Reset Password” button to remove Windows admin password.

Question 2: How to remove BIOS password on Dell computer?

Generally, when we want to remove BIOS password on computer, we just need to shut down computer and move battery from mainboard. But it is just applied to compatible computer. For Dell Computer, no matter your computer is taken with RTC or not, there is a PSWD jumper, also called password jumper. Only remove computer battery or clear RTC couldn’t relieve the password.
So now let’s see how to clear BIOS password on Dell computer.
First we have to make sure that PSWD has two or three needle. For different needle PSWD, the way to clear BIOS password is different.
One: When PSWD is Two Needle
<1> Find out PSWD, and remove power line until main board led turn off.
<2> Remove jumper cap on PSWD, start Dell computer and you will hear the sound of drop. And BIOS password is removed or cleared.
<3> Shut down Dell computer and take back jumper cap to PSWD
<4> Restart computer, and you don’t need to enter BIOS password when you want to access BIOS setting screen.
Two: When PSWD is Three Needle
<1> Find PSWD, and remove power line until main board led turn off.
<2> Move jumper cap of PSWD from 1-2 needle to 2-3 needle, and start computer. You will hear sound of drop.
<3> Shut down computer and retrieve jumper cap of PSWD to 1-2 needle.
<4> Restart computer. Everything is OK.
