Its ofteb so easy to say motherboard and walk away these days. Me and my fellow techs always try to isolate the issue with the boards IC find the actua components at fault and repair. There is nothing more satisfying that bringing something someone has quickly dismissed as dead back to life! Try getting a multimeter and testing the resistors you might have leakage (a resistor letting through the wrong amount of power) there will be other components on thee board that may be at fault too.

Since the model you have is so readily available see if you can get hold of a working one to compare multimeter readings with. If the faulty circuit that has a component that has a variable by comparison of the working model then theres your fault. Replace that part. Most parts you find on motherboards are available at radio shack.

You will probably find 4 or 5 of these parts need replacing but will cost you no more than a total of $5 to fix if you are handy with a soldering iron.

Remember motherboards dont die there compressed boards with carbon tracks. The microchips on them do they are quick and easy to replace.

It's a motherboard issue. There is a component or components that have gone out.

You need to replace the board. Most techs can't fix the problem itself, so a swap is in order.

Batter wont stay charge


Most laptop batteries have a life expectancy of two years or 400 to 450 charge and discharge cycles. After this time, the battery may lose the ability to charge or to hold a charge for substantial periods of time. When this happens, it's likely the battery needs replacement. However, troubleshooting can narrow the problem and ensure you are not wasting money on a battery replacement.

Check Power Adapter Turn the laptop off. Remove any power cords or power sources. Separate the battery from the bottom of the laptop. Slide or press the locking mechanism to unlock the battery. Slide the battery out of the battery compartment. Plug the power adapter into an electrical outlet. Insert the opposite end of the adapter into the charging outlet on the side of a laptop. Power on the laptop. If the laptop does not turn on, the power adapter is not correctly working. If the power adapter is not working, the battery can not charge. Replace the power adapter. If the laptop powers on, the power adapter is properly working. Clean Battery Contacts Turn the computer off. Remove any power cords or sources. Take the battery out of the battery compartment. Dip a cotton swab in isopropyl alcohol. Rub the dampened swab on the battery compartment and battery contacts. Dust and buildup can prevent battery contacts from properly charging. Slide the battery back into the battery compartment. b> Charge and Test Battery Plug the power adapter into the laptop. Charge the battery for six hours. Remove the power adapter. Turn the laptop on. If the laptop turns on and stays on for at least 30 minutes, the battery is holding a charge. If the laptop doesn't turn on or the battery doesn't power the laptop for at least 30 minutes, the battery should be replaced.

My advent battery would not charge so i bought a new one and it still wont charge having to run my laptop from the mains


You may have a DC connector problem:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

Battery drains rapidly


you could fit a switch to cut off the head light if you wont to,,,the problem with honders is they dont charge the battery very much anyhow the most the aulternator put out is 4 amp's thats not very much!
if the lights are on it only just keeps up with whats needed by the lights check the charge rate with a meeter to see if its charging the battery up first if its not then try a new regulator on it, go for a heavy duty one they dony get so hot so they work much better and you wont loos charge from this heating up,

CAN'T get battery to charge. the charger


Hello,

If the laptop will run on the adapter then chances are you have a dead battery. The average laptop battery life is 400 to 600 charge cycles and after 4 years it would need to be replaced very soon anyway.

I hope this helps, if so please rate our solution.

I have an Acer Aspire 3610 notebook. It wont charge


How old is your battery? When you use your laptop, do you run it on just the battery or do you use your a/c adapter and battery? If you're going to use your laptop for an extended period of time, it's recommended to remove the battery and run off of a/c power alone. This helps to extend the life of your battery. Over time, using both a/c and battery will cause your battery to charge/discharge, which dramatically shortens the life of the battery.

You may simply have a dead battery.

Another alternative is that you have a bad power unit, which is what the a/c adapter plugs into on your laptop. My guess is that you most likely have a dead battery.

Cannot recharge battery on my explorist 400 gps


I had the same problem with mine, the AC adapter fails really quickly. Try to go to Radio Shack and get the 3-12v switch able AC adapter that is 1 amp, and select the 4.5 volt setting. This setting is a whole .5 volts less than the one that comes with GPS, but its the Amps that matters. Make sure you get the correct plug with the adapter, I got the "B" plug and follow the directions that came with the adapter to match the right polarity, or you will fry your GPS. Also, the computer just supplies enough power to run the GPS, but not to charge it as long as you have the USB 2.0 ports.

I bought my daughter a laptop (elonex onet) but i dont no how to put internet on it thanks ceri


You have this in the Mac Laptops category, but it's not a Mac. This laptop is running Linux.

The Elonex ONEt has wireless Internet connectivity. That means you can use a wireless router in your home in order to use it online. If you already have one, the system should be able to set itself up to use that connection on its own when you open a web browser. The web browser on your system is BonEcho/Firefox.

Another option is to run a Cat5e, also called an Ethernet cable, line from a router (or from your cable modem or DSL modem) directly to the laptop, since your laptop also has an ethernet port. This looks like a regular phone jack, but it's a little bigger.

Best of luck!
