    My Makita radio shows 'E' when plugged in, but I found a break in the power cord right below the transformer. This is the whimpiest power cord I have ever seen, especially for something that is built for the job site.

    The power cord pulled apart by the transformer, so i got another one with the same amount of voltage but the radio will not work. Occasionally when I plug it in the 'E' will appear and the radio won't work, but when it does work the screen will show the radio stations but the blue back light does not come on and it does not pick up any radio signals. I'm not sure what to do in this case, do you have any suggestions?

Usually the blinking E means the backup batteries are dead.

the backup batteries are AA and should go in the lower compartment on the rear of the radio.

just make sure you install the backup (AA) batteries in first, then insert your main battery to run the unit. doing it backwards wont always clear the "E" notification

Makita worksite radio ,a sparky told me to use a plug with a low fuse in it instead of the ac adapator turned it on and it went phhhtt!!! is it ruined or is there a solution?

    It is probably broken, with and ac adapter u are actually changing the voltage from 120v to 12v . So instead of giving the radio 12v you introduced it to 10x that much. I would open it up and see if there is some sort of fuse inside. Also I wouldn't get any more advice from that sparky.

Laptop won't start up

I'm inclined to think that your power cord is bad and you have drained your battery.
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

I power on my lenovo g55o, the power light come on, the battery charging light and the hard drive blinks for a couple seconds and goes off, but the monitor never lights up

You can try switching off computer, unplug the ac adapter, then the battery. When all power source are removed, hold the power button. Then put the battery back on then try switching the laptop back on.

Unfortunately, I had this problem before with a waterproof camera!

Once the water bridged the circuits, it did irreparable damage.

If it had dried out WITHOUT voltage running through the camera, it might not have caused any issues.

Best option is to remove any batteries and power cables, and let it dry out completely. Check to see if the problem persists, and if so, consult the manufacturer for a repair.

Radio receives but will not transmit. Call button will also not transmit. The LED on good radio blinks once every two seconds. The Led on bad radio blinks once every three seconds. Do I trash the bad...

Here are a couple of things to try before trashing the unit:
1) Check your programming to see that your frequency, code and Qt filter (if any) match identically. For simple operation set your Qt filter and code to off (zero).
2) Swap the batteries between the two units, see if the problem moves to the other unit. If so, you have a bad battery pack.

Here is a link to the user guide:

Best regards.

My problem is exactly the same as the original poster's.

It may be that there is a setting in the camera that has been changed to make the camera only operate from the computer. I suggest looking around the menu in the camera when it is attached to your computer.

Well first off in doing so removing the batterys before you powered it off its stuck in some kind of error mode. Try putting the batteries in, holding the power button down for a few seconds and see if the light stops blinking.
Second Idea if you have a local radio shack they have replacment power cords for radar detectors there about 10 dollars. I had to go buy one for mine. After powering it up with that Id say it should work fine.
