Tips on Laptop Repair
Laptops are complicated pieces of equipment but repairing one may not be as expensive as a laptop repair technician may lead you to believe. It is important to carry out thorough research before embarking on a laptop yourself. Ensure that you have a few basic items to assist you rather than making the common mistake of grabbing anything nearby. A Laptop is not an inexpensive item to replace so it is worth avoiding unnecessary mistakes.
This article is intended as a rough guide of tips for laptop repair, there is plenty of information out there on the internet that will help with specific enquiries. Make sure you ask all the questions before you begin to attempt a repair yourself, if you don’t do the research you may be charged more for someone to correct the mistakes that you have made. Should you decide to undertake a repair be sure that you have a good understanding of what needs to be done, if you don’t have the first idea seek professional help.
Before you begin it is sensible to make sure you have long nosed tweezers, an electric static discharge mat, a Teflon wedge, needle nose pliers and Phillips head screwdrivers size 0 & 1. Take a back-up of everything on the hard drive before beginning the repair, just in case. It is best if possible for the repair to take place in a room without carpet.
One word of advice if you are playing around with the LCD the backlight inverter can give you quite a nasty shock if the laptop is powered up. So ensure that the laptop is switched off and unplugged from the mains. It is also sensible to remove the laptops battery and hard drive before beginning a repair.
Obviously if you are a novice to laptop repair you will probably not own anti-static gear like wrist straps etc, if there is a likelihood of you carrying out laptop repairs regularly it may be worth investing in the anti-static gear, rather than killing off your laptop and having to dump it in the rubbish.
When carrying out a repair do not disassemble the laptop unless it is necessary to do so. Try to ensure the environment you are to work in is clean and make sure that you have the correct tools. Before beginning the repair make sure that you test the machine properly, you need to have the correct symptoms to diagnose the fault. If you need to remove any parts of the laptop take care to keep the parts in a safe place where they won’t get damaged. When removing screws keep them with each part they have been taken from, this will help when reassembling the laptop. When fitting the laptop back together use the correct size screws for each part, this will prevent you ending up with screws that simply do not fit the holes you are left with. Before disconnecting connectors make sure that you have had a good look at how they work, it is worth making notes for yourself as you carry out the repair as it will help jog your memory.

Three Things To Know About Using A DC-AC Power Inverter
The first thing you will need to know is what you are planning on running in this time of emergency. The fewer the items or the smaller the amperage, the smaller or least costly inverter will be needed. I will give a simple formula that will give you an idea of the size of inverter you will need.
If the appliance you are planning on using is listed in watts, just go ahead and use that number. If it is listed in amps you just need to use this simple formula: volts (120) X amps (listed on device) = watts. This will give you the amount of watts the appliance will be using. So if you had a 3 amp appliance, and you wanted to find the watts, the formula would be: 120 (volts) X 3 (amps) = 360 watts.
You would then total all of the watts that you will be using and come up with a number. Lets say your total watts usage is 500 watts. If that's the case it would be a good idea to get a 750 watt inverter. Always get a larger size than what you think you will need, it may come in handy.
Your next step will be to determine where your power supply is going to come from. If it is for emergency purposes there is a very good chance that it will be coming from a battery hooked up to your vehicle, or you may be a little better prepared and have a bank of batteries hooked up in a parallel fashion. Since most people reading this are probably unfamiliar with creating a battery bank I will just cover running the inverter from the vehicle. The main thing to know is what type of battery you will be using. It is suggested that you have a deep cycle battery or those that are used for trolling motors or golf carts and that you get as many amp hours as your budget allows. A few years back I was able to go 11 days using a 750w inverter and a 120amp hour deep cycle battery attached to my car. I had to run the car for 10 minutes every 2 hours to run everything that I had hooked up which was a laptop, 13" color tv, direct tv receiver, modem for the laptop, 40w light, and a small box fan. That doesn't sound like much, but I thought I was staying at the Ritz Carlton compared to most of my neighbors.
The last thing you need to know is how long will your power supply (battery) last before it needs recharging. First you will need to know the wattage of all the appliances. Lets say we have 480 total watts of power being used, and we are running our inverter off of a 12 volt battery attached to the car. Next we have to convert this number so that we know how many amps are being used. We do this by taking the watts (480) and dividing it by 12 (volts of the battery) and come up with 40 amps. The formula is: watts / volts = amps. If we have a 120 amp hour battery we would divide 120 (amp hours) by 40 (amps) and get 3 hours before the battery is dead. It is recommended not to drain a battery below 50% of its capacity so you may want to divide the 3 hour in half giving you 1 1/2 hour before starting the car up to recharge the battery.
I hope this helped you determine what you will need in case of an emergency where you will lose power for an extended period.
