• Replacing DC Power Jack

Slide your electrostatic discharge wrist

Slide your electrostatic discharge wrist  strap onto your wrist. Lift the motherboard up and out of your laptop and set it aside. Now apply soldering iron to the three contacts of the power jack to heat up the existing solder on the contacts. Having applied the soldering to the contacts  of the DC jack, use the desoldering pump to remove the solder from the power jack. You then shake the DC jack until it separates from the motherboard.  Having separated the DC jack from the motherboard, apply the soldering iron to the jack pins and the DC jack.

Lay Replacement Jack
Lay the replacement jack in the original  position of the old jack. After the replacement go ahead and apply solder to the jack pins and DC jack and then put the motherboard back here you removed it. And then finally reassemble your laptop.

Tell-Tale Signs That Your Laptop Is About To Crash Part I

We all know that laptops crash quite often and without warning. And when that happens you're left totally helpless. So the only thing left for you do in this situation is wait for a reboot or force a reset manually. What makes  a laptop crash so frustrating is the randomness of the crash. One minute your  laptop is fine, and the next minute, it crashes and takes all your precious files along with it.

However not all crashes are that random. There are  potential signs of impending doom that you should look out for in such a situation. These signs may seem like a nuisance to you but they may point to a an even bigger problem that can result into a huge crash and become a huge inconvenience for you.  Here are five  tale signs that your laptop is about to crash

Hardware Conflict
Sometimes you get a a situation where two laptop components gobble up all the resources. This causes hardware conflict, which manifests into freakish behavior while certain tasks are being performed. For instance, audio conflict might render certain programs useless . But not all programs suffer the same fate. Not all hardware conflicts disable laptop programs, but they do cause the dreaded blue screen of death, or, a reboot of the operating system.

The best way to catch hardware conflict is to open the Windows Device Manager.  You can find the Device Manager in the Control Panel.  Now once you get into the Windows Device Manager  you'll see a yellow exclamation mark. That's a sure warning that you have hardware conflict. Now having established this fact, try re-installing the drivers for the defective hardware. If you experience difficulty trying to stop the two piece of hardware from clashing with each other, you can go ahead and disable one in the Device Manager. If that doesn't work, you will have to remove one of the conflicting components.

Random File Or Program Corruption
One bonafide sign of a  laptop about to crash is random file and program corruption. All of a sudden, these files stop working, or they seldom work, and they rarely come with any error message. So to diagnose possible problems, scan your laptop hard disk for possible malware with an  up to date anti-virus software such as Avira. It's possible a virus could be the cause of your file corruption problems. Also check your hard drive for errors, and if that doesn't work, go back to the Window Device Manager to check for possible hardware conflict. Usually behind this conflict is a driver issue.

Noisy Hard Drives
Noisy hard drives are the  most persistent cause of most laptop problems. Although they've improved in quality over time, their mechanic parts still wear out- a  stark reality laptop users must get used to.  

Another possible sign of hard drive demise is programs loading too long.  You should check your hard drive for errors, but you need to back your files before , or just in case your  hard drive crashes. 

Boot Device Not Found
Another sure sign that your laptop hard drive is on its way out is  the dread"Boot Device Not Found."  Now in this scenario, windows usually fails to boot, but but will respond later- even if you hit the reset button.  That's a sure sight that your hard drive  is about to peter out or your windows installation is  corrupt. In that case replacing the hard disk or  or reinstalling windows is your only recourse.

However, a note of caution. Before carrying out either operation, be sure to unplug any external drives plugged into your laptop. This to avoid your laptop making the fatal mistake of reading your external hard disk. This make cause a boot error.

Poor Form
Poor form, or poor general  performance is a consequence of multiple programs you installed on your laptop. This is puts a lot of pressure on your laptop and forces  it to overcompensate.This of course  causes the laptop to perform poorly. Cleaning the windows operating system might help somewhat, but to  save you further misery, you'd be better off re-installing  your operating system.

If the problem still lingers, blame it on  your hardware.   Your best bet is to try a benchmark program such as Clickfix Utilities,  to determine the component  slowing down your laptop. Based on the testing results, you then determine whether that component should be replaced.

That's A Wrap For  "Tell-Tale Signs That  Your Laptop Is About To Crash Part I". Next Week we'll  continue with Part II. Till then take care.
