How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

If your laptop won`t power on, even when it`s plugged in could have a faulty power supply, battery, motherboard, video card or RAM. When troubleshooting a laptop that won`t start, begin with the basics. Ensure the plug to the power cord is plugged into an outlet and to the computer.
There`s no danger of overcharging a battery if you leave it plugged in all the time, even 24/7. As soon as it hits 100 percent, it will cease charging and won`t start again until the voltage falls below a certain level. Fully discharging a battery will damage it.
You Have a Faulty Cable, Adapter, or Power Outlet

A damaged charging cable is one of the most common causes of charging issues and is one reason your charger will stop working. There are many ways cables become damaged, leaving wires exposed or broken.

You can fix a laptop that only works when plugged in by disabling and re-enabling the ACPI-Compliant Control Method Battery and restoring the default power schemes in your power profiles within Windows 10. These methods should work for HP, Dell, Lenovo, Acer, and other laptops that won`t turn on unless plugged in.
Locate and remove the battery. Press and hold the power button for 30 seconds. Re-insert the battery and plug in your laptop. Attempt a restart and cross your fingers.
Press the “Fn” key and the key with the monitor symbol a couple of time to see if an image appears on the external monitor. If an image appears on the monitor, the problem is with the LCD screen of the monitor. If no image appears on the monitor, either the video card or motherboard in the laptop is probably defective.
Does leaving a computer on 24/7 damage it? No, in fact it`s better for it. Most don`t have spinning drives any more, but a hard drive that spinns lasts longer the fewer times it`s started and stopped. Fans still require a motor and they are most likely to fail when starting.
When a laptop is plugged in and turned on, the adapter may be warm to the touch. A relatively warm power adapter is normal, especially when the laptop is in use while the battery is charging.
You can Use a Laptop without the Battery

First of all, make sure you`re using the original power adapter that came with the laptop. Power variations could cause components on the laptop`s motherboard to fail, which is something that the battery can prevent by acting the way a UPS would.

Then remove the charging cable and see if your laptop remains on, or if it still powers off. If your laptop turns off immediately when you unplug it from a power source, it means your battery is not working. Most likely, your battery has reached the end of its useful life and has stopped holding a charge.
Common culprits include a faulty motherboard, damaged charging circuits, and malfunctioning battery sensors. Your particular make and model of laptop will likely have its own unique issues, and a seasoned tech support operator will have seen all of them.
If your laptop battery shows 100% but dies when unplugged, the issue might be with the charger. There is a possibility that the charger you are using is not providing sufficient power to your laptop or it`s not properly charging your laptop.
Press and hold the power button for 10 seconds when your screen or keyboard lights up, or when you see the manufacturer`s logo. Release the power button when your laptop shuts down. Press the power button to turn on your laptop.
A 24-hour charge makes sure the battery is full and helps with the battery`s life expectancy. Once it is fully charged, you should not discharge it fully, if possible. Lithium-ion batteries (the type used in modern laptop computers) are strained and may be weakened when they are fully discharged.
An outdated or malfunctioning application or driver can lead to black screen errors. Graphics drivers are particularly suspect when it comes to these errors, although issues such as Windows Explorer not running properly can also be the cause.
Check the power supply and battery

For example, the problem could be as simple as having the wrong charging cord which means you aren`t getting the proper voltage, or it could be that the power supply has failed [2]. 1. To test if the power supply is the issue, completely remove your laptop battery.

Most laptops can last anywhere from 3 to 10 hours. If your Mac or PC needs to charge up more frequently—or if a full charge lasts only 15 to 30 minutes—it`s time to replace the battery.
If your laptop battery shows 100% but dies when unplugged, the issue might be with the charger. There is a possibility that the charger you are using is not providing sufficient power to your laptop or it`s not properly charging your laptop.

My swimming pool. I have just had my fifth IC 40 Intellichlor chlorine generator installed in 4 years at a cost of over $900 today. Each one has worked for no more than 8 months. The first three were replaces under three year warranty, the fourth by a factory rep and I bought the fifth today. The first three all failed with Flow Chk PCB error message. The fourth just stopped working on Sunday, no power or lights. A local Pentair warranty person, whom I paid a Service Call, unplugged the unit, opened the small power center cover, showed me the green light indicating that there was power, plugged in a new IC 40 which worked immediately (as did the other four). I asked if I should replace the power center and he said that it’s basically just a transformer and is working fine. We do get occasional power blips that make the clocks on microwaves, etc blink, but I thought that the power center essentially isolates the cell from these. I do have a Florida Power and Light surge protector on the electrical box that brings power into the house. I have now talked to the pool builder, two Pentair warranty repairmen and one factory rep. I am at a loss. They all tell me they have no idea why these units fail after less than a year. This last IC 40 was installed 3/24/2010, version 2.0 and now failed in less than 5 months. Should I replace the power center that the IC 40 plugs into. Any other suggestions. I have been told that this is the best chlorinator. I don’t want to keep replacing units. By the way, each unit had been spotless inside. I keep the water chemicals and salt levels at ideal levels. The units have never worked long enough to get dirty inside. The power center is connected to an Intellitouch control system outside with an indoor control panel. Last time I called Pentair North Carolina and got some smart alec tech person that had no suggestions. Please Help if you can.
ANSWER : I’ve had the same experiance. On my fifth one as well. Fail every year. No idea why.

I just purchased this Yamaha boat w/Twin MR-1 140hp motors, less than 100hrs (60 prox)and the starboard motor only reached 8000rpm on a 10000 redline spec (the port motor reaches 10000rpm. I have replaced the spark plugs immediatly and now the motor reaches 9500rpm. When the plugs were replaced the plug wire top of the plugs had a black powder residue (like graphite)and #1 & 4 plug electrode end were black minimal soot and #2 & #3 had a white color residue on the ceramic.

Any suggestions to attain the full 10000rpm?

A Yamaha dealer is 100 miles, so I would like to fix myself if possible. Thanks

ANSWER : I never rec’d an answer…..I WANT A REFUND!

Although the ground wire from the battery to the start is intact I do not have a ground on the engine. The starter doesn’t work. The backup buzzer doesn’t work. Nothing works. What went wrong?
ANSWER : Jim,

You need a ground wire to complete the start circuit. By the way what are we working on?

I have a wildwood le 25bhbs and the only towing lights working are my signal lights. can’t get running lights or brake lights to work. I saw where it looked like the towing harness may have been pinched. So I repaired that, but, they still do not work. Any ideas? Is there a fuse somewhere I need to check? Do I need to hook the trailer up to my trailer hitch before they will work? Is there a wiring diagram or repair manual somewhere I can get? Any help would be greatly appreciated. Thank you.
ANSWER : There should be an inline fuse, check that first.

Spark plug wire boot grounding out on coil, 96 outback 2.5 automatic, just put new spark plug wires, new spark plugs, and new coil on. ran great for two weeks, now spark is jumping out of boot at coil on one wire, put old coil back on and still does it in the same spot. replaced wires again, and still does it in the same spot. seems to do it only under a load. Is my new spark plug on that cylinder bad? Does the coil need some insulation under it? It is the coil that sits right on top of the motor. Any ideas? thanks.
ANSWER : Sparks are high voltage, and will always follow the path of least resistance. If you can visibly see a spark (whether in a lighted area, or in the dark), that means either that a plug wire (or coil wire) is open (non conductive), or your have a carbon track on the surface where the spark can be seen, but most likely you have BOTH problems!

If you have an ohmmeter, check the resistance of each wire involved, particularly spark plug wires … which means you must be able to connect to both ends of each wire at the same, and hopefully, FLEX those wires, to be sure they don’t have a break inside that is intermittent (comes and goes)!
