Amp turns on but puts out no sound except for faint noise which dies out after a few seconds.


It sounds like a defective/incorrect AC-to-DC adapter may have caused your problem. These adapter come with different output voltages, AC or DC output and different amperage ratings. AC-to-DC adapters list the polarity of the DC voltage as it relates to the DC power plug and you must match both the devices voltage and power requirements. As for the amp...not working on batteries either, I would suspect output transistors or IC.

Ti-5033 sv calculator, the 6 volt adaptor doesn't


Hi,
No...most of the time it is the jack in the back of the machine where the adapter plugs in that goes bad... the problem is usually not the adapter but the plug in....

Why does laptop stop working through adaptor after battery flat


Hi There,

Your battery charger/adapter connects to the DC Power Jack to power your laptop and charge the battery. Since the charger/adapter does 2 things, there are 2 "cells" inside it to do those 2 different things. It's not uncommon for one or the other (but not both) to fail. So, often just purchasing a new charger/adapter solves the problem you're having. It appears that yours is continuing to charge but has stopped "adapting" AC current to DC current to power the laptop directly.

Hello all you electronic nerds. I have a simple question so please do not try to give me a college education in your answer. I have an 16.8 drill battery without a charger. i need to find out if it will...


No. Not unless you also use the right size diode to make the AC go in one direction only.
AND---- Don't try anything like this with a Lithium battery! We're talking NiCad, right?

Hit Navigator key, takes a very long time 20+ min to find location.


There is a problem with your battery level. Make sure its fully charged. if it does not hold a charge when off the power for at least 2 hours then change it. 99.9% of the time low power delays connection to satellites. the max timke is about 9mins but average 1-2mins .....20 mins is not acceptable. I would suspect the battery.

DO NOT power the unit prior to starting the engine when using DC plug of car This will burn off the IC CHIP and damage your units battery.

No power


My magic mike does have power, but a couple of my song chips comes up garble, and unable to bring song up, where as a third chip is able to play . Some times when I run through the list there will be some songs that pops up but not all. Then after a while it will go gargble again, but the third chip is okay.
This is when I use the AA batteries, If I remove the batteries, then it will come up data check, and garble...........any solutions or answers? Thanks

3rd light from top not on


Hi,I would suggest you to first trying unplugging/ switching off your device for 5 minutes. This restores and refreshes the device. Go for it
Let me know if this works, if it doesn’t then I’ll provide some other alternative solution.
Thanks

Defintely getting power, but not switching on.


There are several possibilities. Let's start with the easiest two. First the battery, take it out and try starting up only with the power supply. Then the memory chips. If a memory chip fails it can cause a no start in IBM's. Take the memory out and try it. Then try it, putting them in one at a time. If these don't work, then I'm afraid your problem lies within. Namingly the power management chip on the motherboard. The pm chip controls the power input, and allows such functions as switching between battery and AC, and battery charging. The pm chip can go without warning, and just because it lights and shows charging doesn't mean this chip hasn't malfunctioned. I've had several IBM's come through my shop that have experienced the same problem you're describing. I've also had them with problems like; it will only power with the battery, won't charge the battery, will charge battery and only run with battery shuts down while charging, only power under AC, etc... all pm chip related issues. Unfortunately, the only solution is motherboard replacement.

Lap top problem


Hi

If the AC power light is blinking, try the following steps:

1 Cut off power to the computer by disconnecting the AC adaptor and removing the battery. The error condition will be interrupted, and the AC power light will stop flashing.

2 Put the battery back into the computer. Do not connect the AC adaptor. Try turning the computer on again. If the computer starts normally, the AC adaptor may be
defective and will need to be replaced. If the AC power light starts flashing, remove the battery, and continue with the steps below.

3 Connect the AC adaptor to the computer. Leave the battery out of the computer. Try turning the computer on again. If the computer starts normally, the battery may need charging, may be depleted, or may be defective. Turn the computer on, insert the battery, and then leave the computer running for several hours, which will deliver a slow, steady “trickle-charge” to the battery. Once the battery has been trickle-charged, it may begin working correctly again. If the trickle-charging does not prove effective, consider replacing the battery with a new one.

4 Connect the AC adaptor to a different power outlet, preferably in a different room. If the computer starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it.

5 Verify that the AC adaptor is the correct unit for your computer model. The computer may not be able to start from an AC adaptor that is rated for less current (amperage) than the computer requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the bottom of the computer and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the computer
