How to find the problem when your Laptop is Failing

Have you ever met the problem when your laptop was going to fail? Perhaps you hear some weird noises coming from the machine. Perhaps your laptop is taking too long to boot up, or maybe the screen is appearing kind of dim. So you need check out where the problem is, below is some guide about it.
Dead Pixels In The Screen. Usually, if you have dead pixels (unlit pixels) in the laptop screen, you can return them to the manufacturer to get a replacement laptop. This depends on the manufacturer's policy though - some of them only replace the laptop if you have more than say, 9 dead pixels across the whole screen. If you suddenly see several dead pixels in the laptop screen, it usually points towards LCD monitor damage, so watch out for this.
Battery Power Runs Out Too Fast. Yet another common problem is a battery that runs out of juice within 10 minutes, even though it is fully charged. The problem here, fortunately, is usually with the battery unit and not the laptop itself. So in these circumstances, get yourself a new battery. In certain cases, it could be due to faulty circuitry in the laptop body, though this is rare.
Memory Problems. Laptop memory modules are also prone to failure. When you boot the laptop up, try to check the amount of memory (RAM) available in the machine. If you know your laptop has 2GB of RAM, then the boot up screen or BIOS should show 2GB of RAM. If it shows less, it means you have a faulty memory module - which slows down your system immensely.
Weird Hard Disk Noises. This is the most worrying sign from a laptop - a claking, or loud whirring sound from the laptop hard disk drive. Usually, a whirring hard disk drive means that the drive is starting to falter or fail. You should immediately back up all your important data! I once heard such noises from the laptop hard drive and within 2 days, the disk had crashed. And this tell tale sign of hard drive failure is usually spot on - so please watch out for this one.

Acer Aspire 5720 AC adapter power supply Troubleshooting

Laptops come with an adapter that plugs in and attaches itself to a little metal electricity conductor inside the computer. These little Acer Aspire 5720 AC Adapter power jacks can easily come undone, leaving your computer to run out of battery. To have this repaired by a professional, it can cost you upwards of one hundred dollars just to have them look at it.If your laptop isn't turning on, it is most likely one of two issues: the power cable or the battery. It is important to attempt to isolate an issue prior to calling customer service, as you will either be able to fix it yourself, or will be able to provide more useful information to the technical support agent.
If you want to fix the Acer Aspire 5720 AC adapter yourself, the following may help you:
Flip your laptop over and remove all of the screws. Be sure to unscrew the ones holding the screen in place. Some screws are different sizes, so keep them sorted in order of where they were removed. Uncover the hard drive housing located at the bottom front of your laptop. The hard drive will be screwed in, so you have to remove those screws before you can take out the hard drive.
Test Electrical Outlet
Plug a different device into the electrical outlet you are using. Occasionally, the issue is not with the laptop at all, but rather a bad Acer Aspire 5720 AC adapter power outlet.
Inspect the Power Cable
Inspect the power cord using vision and touch. Check for any nicks or gashes in the cord, and feel for any possible issues such as a break in the wire inside.
Check Power Cable Connection
Verify that the Acer Aspire 5720 AC adapter power cable is properly plugged into the outlet, the laptop and the transformer box in the middle of the cable, if there is one.
Remove the Battery
Power on the computer with the Acer Aspire 5720 AC adapter power cable plugged in but with the battery removed. This will determine if the battery is the cause of the problem.

Change an AC Adapter for a Dell Inspiron 1000, How?

PC and mobile devices such as laptops operate off of direct current (DC) energy. Standard household jacks, and almost all businesses in the United States make use of alternating (AC) current. This means that all computers need a special Dell Inspiron 1000 AC Adapter that will temporarily store a charge from the AC current to provide an even flow of energy to the DC input jack. These power supplies are composed of a multi-wire cord connecting to an laptop AC/DC adapter, which then has a single direct-current cord that leads to the laptops DC input jack.
If you really want to repire Dell AC Adapter yourself, follow this steps:
Use the internet to select the proper laptop ac adapter for your computer. Entering the model number of your laptop such as the words "Dell Inspiron 1000 AC Adapter" in a search engine will result in a list of products you can use to replace your faulty power supply.
Disconnect your old Dell AC Adapter from the laptop. This includes the entire power cable and AC/DC adapter. You may be able to reuse the cords of your old unit, such as if they are longer. Assemble the new Dell Inspiron 1000 AC Adapter that you purchased earlier. The AC cord connects to the AC/DC adapter, which connects to the DC cord, which finally connects to the laptop.
Check the light on the AC/DC adapter is lit. This will indicate that the Dell ac adapter is receiving power. You should also check your Windows desktop in the lower right hand toolbar for a power charging icon; it will look like a battery with a lightning bolt flashing on it.
Warning: Before replacing a laptop ac adapters, ensure that it is broken by firmly connecting each piece.

Porsche will be offering a starter lithium-ion battery

In the press release that cited the reasoning for the decision, Porsche reveled in the fact that they will be first car maker in the world to offer a starter battery in lithium-ion technology.
“Delivery of power by the lithium-ion battery throughout its useful charge range is likewise significantly better, providing its full power, for example, when starting the engine almost independently of the current charge level. Yet a further benefit is that a lithium-ion battery allows a significantly greater number of charging and discharging cycles, plus the two further advantages that the self-discharging effect is lower and the service life of the battery longer,” said Porsche. “The lithium-ion battery being introduced by Porsche as the pioneer in this area is made up of wound film of carbon and iron phosphate with a ceramic film moisturised by the electrolyte serving as a separating layer in between.
One of the main reasons for this move by Porsche is the weight, or lack thereof, that the lithium-ion battery features. Weighing less than 13 lbs, the new battery is more than 22 lbs lighter than a conventional 60 Ah lead battery. Aside from being lighter than it’s lead counterpart, there were several performance-related statistics mentioned by Porsche as deciding factors.
Compared with other types of lithium-ion batteries using a combination of manganese oxide, cobalt oxide or nickel, this lithium-iron-phosphate battery, as it is called, offers advantages when used as a starter battery. It is robust and consistently guarantees the usual voltage of 12 V in the car’s on-board network.”

Microsoft's new and pricey Wireless N adapter with Xbox 360

It seems like some companies see Microsoft's new and pricey Wireless N adapter for the Xbox 360 as a prime candidate for some competition. One of the first out of the gate is Mad Catz, which has just released its new Wireless-N Gaming Adapter that packs a slightly more reasonable MSRP of $80 (twenty bucks less than Mircosoft's), and should no doubt see even bigger discounts than the official Microsoft option.
As you may have already guessed, however, this one is actually just a standard wireless bridge aimed at the gamer crowd, which just so happens to mean it'll also work just fine with the PlayStation 3 if you're looking to step-up to 802.11n or take advantage of the forthcoming Adhocparty service.
Following the release of Microsoft's improved Wireless N Networking Adapter for Xbox 360, Mad Catz has announced its own wireless adapter, which improves upon Microsoft's device in a couple of ways. First, the adapter, essentially an Ethernet bridge, works with the PS3, allowing for the use of the 802.11n standard with Sony's console.
Second, and most importantly, the Mad Catz adapter improves upon the most reviled feature of the Microsoft model: the price. At $79.99 (£49.99/€59.99 in the UK and Europe), the Mad Catz Wireless-N Gaming Adapter is no impulse buy, but it's exactly twenty dollars better than Microsoft's version. Mad Catz told Joystiq that its device is currently shipping to North American and European retailers and will be available in the company's online store this week.
The OP is talking about using an actual router, not a bridge. You can often use routers, but they usually take a bit more configuration than a bridge. Plus, the OP is also talking about flashing a router with a 3rd party firmware. That step alone will make most consumers say "Screw that" and choose the less complicated option.
