HP Pavilion DV6000 adapter (charger) repair

Many of my friends have issue with their laptop adapters (charger) including myself, the wire of the adapter gets damaged and it does not supply the required electric power to the laptop. Usually, we try to bend/move the adapters wire to make it work. Sometimes it works but anyway the wire is damaged so you have to buy a new adapter for your laptop. I was also thinking to buy a new adapter for my laptop but then I thought I should try to repair the adapter and I repaired it. Below is the same procedure as I did, the only difference is I repaired both sides of the wire, the connector and the other end which connects to adapter. Procedure shown below was posted Here

Repaired a HP Pavilion DV6000 laptop charger cord over the weekend.  The cord had become frayed extremely bad close to the connector that plugs into the laptop and needed to be replaced.  The job was fairly easy and straightforward, but if you don’t feel comfortable with a soldering iron/gun or electrical jobs in general you may want to leave this to someone else.  But if you aren’t scared to try something new, and let’s face it, you don’t have much to lose at this point if you are reading this, this can be a low-cost quick fix.  Worst possible outcome is you have to buy a new charger cord, which you were probably already planning.  

As always with any tutorial, please proceed with caution and at your own risk, I make no guarantees. Cords can overheat, you could get electrocuted, you could fry your laptop, etc..

Frayed Cord

This picture shows the bad condition of the cord, all I’ve done here was cut the connector off.  You can see how badly the outside wire is frayed.  I think the wire in the white sleeve was still intact but I had to cut all of the bad section out to get to some clean whole wire.

Cord Cleaned Up

I’ve gotten the cord cleaned up and now ready to solder back to the cleaned up connector.  

Just trim all the damaged cord out of the way, strip back the wire jacket to expose a small amount of the center wire that will connect to the center part of the connector.  I left the outside silver wire a little longer in order to reach further up on the side of the connector to avoid having to bend the wire or have a kink in it.  Then twisted the wire to have it all neat and compact.

Cleaned cord w/ old connector

This picture shows the cleaned cord with the original connector.  My local radio shack store didn’t have a new connector so I chose to clean up the original connector to see if it would work, and it worked just fine.  I heated up the solder on the connector and the bits of broken wire came right off.  I then took a small file and cleaned up the leftover bits to make it nice and clean.

HP Cord resoldered to Cleaned connector

Now we have the center wire in the white sleeve soldered to the end of the connector.  I put a small piece of electrical tape around the center wire before I soldered the outside silver wire to keep them separate.  I then clamped the connector and wire back down and soldered the outside wire to the side of the connector.  Be careful how you hold or clamp the connector.  It could get very hot, and it could also warp or break the plastic pieces.

Finished charger cord

I reinstalled the plastic insulator boot around the soldered connections and wrapped it tightly with electrical tape.  I chose white electrical tape (since it stands out more) as sort of a reminder to not snatch and pull on the cord as this is a refurbished job and while it will probably hold for a long time, it would be better not to abuse it.

We Have Power!!

Let everything cool off and sit for a few minutes and then plug it up and see what happens.  Hopefully if everything went well, you now have power.  If not, wiggle the connection around slowly and see if anything happens, if it does come on, you may just have a loose connection and might need to take it apart and recheck everything.  If that doesn’t solve the problem, you might have damaged the connector itself or may have bigger issues.  But I hope you see a power light and the laptop comes right back to life like my example.  Good luck, it was a much cheaper fix than the $80.00 they wanted for a new cord.

Solve Printer Spooler Problem

Many times you face problems with your printers, one of them is, "some print jobs are stuck in printer spooler". you tried but could not cancel or delete the print jobs, whatever the reason behind it, you can solve it by running a command script as shown below. 

1. Click Start, and then click Run.

2. In the Open box, type notepad, and then click OK or goto Start>Programs>Accessories>Notepad. Notice that a blank Notepad document opens.

3. Carefully select (highlight) the following text:

net stop spooler

del %systemroot%\system32\spool\printers\*.shd

del %systemroot%\system32\spool\printers\*.spl

net start spooler

4. Right-click the text that you have selected above, and then click Copy or press Ctrl+c. 

5. In Notepad, right-click in the blank document, and then click Paste or press Ctrl+v.

6. Now, save the file to a location from where you can access it easily (e.g. desktop, drive C, drive D, etc) with any name you want but with ext ".cmd". In this example we will save it as "DeletePrintJobs.cmd".

Note this file name differs from most other file names that you might have seen. That is because this file is a command script file.

7. Now that you have created the command script file, you have to run it, to solve printer spooler problem. Goto the file where you have saved it earlier and double click on it.

6. Notice that a Command Prompt window opens to run the command script file that you created. Notice also that this window automatically closes when the command script file finish running.  If you do not see the Command Prompt window open, check that you saved the command script file with correct name.

After running the command script file successfully, print something on your printer, it should be working fine now.

Note: If this method does not work the first time, or if you cannot print anything after you use this method, restart your computer, and then try again.

Fix NTLDR is missing in Win XP/2000

 

Issue:

NTLDR is Missing.

Related errors:

Below are the full error messages that may be seen when the computer is booting.

• NTLDR is Missing
  Press any key to restart
• Boot: Couldn't find NTLDR
  Please insert another disk
• NTLDR is missing
  Press Ctrl Alt Del to Restart

Solutions:

1. Computer is booting from a non-bootable source

Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk or CD-ROM. First verify that no floppy diskette or CD is in the computer, unless you are attempting to boot from a diskette.

Note: This error has also been known to occur when a memory stick is in a card reader and the computer is attempting to boot from it. If you have any card reader or flash reader make sure that no memory stick is inside the computer. Additionally disconnect all USB drives, cameras, ipods, iphones, etc. from the computer.

2. Computer hard disk drive is not properly setup in BIOS

Verify that your computer hard disk drive is properly setup in the CMOS setup. Improper settings can cause this error.

3. Corrupt NTLDR or NTDETECT.COM file

Windows 2000 users:

If your computer is using Microsoft Windows 2000 and you are encountering the NTLDR error. Create the below boot.ini file on the floppy diskette drive.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect

Copy the NTLDR and NTDETECT.COM files from another computer using the same operating system. Both of these files are located in the root directory of the primary hard disk drive. For example, C:\NTLDR and C:\NTDETECT.COM should be the locations of these files on many computers.

• How do I view hidden files in Windows?

Once these files have been copied to a floppy diskette reboot the computer and copy the NTLDR and NTDETECT.COM files to the root directory of the primary hard disk drive. Below is an example of what commonly should be performed from the A:\> drive.

copy ntldr c:
copy ntdetect.com c:

After the above two files have been copied, remove the floppy diskette and reboot the computer.

Windows XP users:

1. Insert the Windows XP bootable CD into the computer.
2. When prompted to press any key to boot from the CD, press any key.
3. Once in the Windows XP setup menu press the "R" key to repair Windows.
4. Log into your Windows installation by pressing the "1" key and pressing enter.
5. You will then be prompted for your administrator password, enter that password.
6. Copy the below two files to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer.
   
   copy e:\i386\ntldr c:\
   copy e:\i386\ntdetect.com c:\

7. Once both of these files have been successfully copied, remove the CD from the computer and reboot.
8. You can do this to check your new boot ini file if you wish but this step can be skipped if you are confident that all is good.
   
   Type: type c:\Boot.ini
   You should see something like this:
   
   [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS operating systems multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /fastdetect.      
9. If the system does not show the above result as in #8, run these commands one by one:                    

         Chkdsk 

         Chkdsk /p 

         Chkdsk /r

After finishing restart the system, Windows XP should boot up properly this time.


That’s all....!
