My nexxtech multination travel adapter specifically says on the label that it will convert 240/220 V to 120/110 V, but when i plug it into a 220 V wall outlet its output is still 220 V. (I know this since...


It seems your adapter is not a converter for Voltage, but just a plug-converter so it will fit all type of sockets. There's a varistor for safety-protection, but that's all there is. At least, that's what I make up, based upon your description and the manual. See http://downloads.thesource.ca/273/2731445/manuals/manual.pdf

If the converter also should have converted 220/240 V AC into 110 V AC, than the electronics inside is damaged. Actually I think it's just a plug-converter, because there are many devices operating with an internal switched powersupply. The advantage of such technique is it can operate at various AC-voltages, whil only an adapter for the correct plug is needed.

Our window AC unit stopped suddenly. Completely dead. The outlet has power. It's a 220V unit. LG window AC LW2510ER Any advise what it could be? Does it shut down when it's 100F outside? Thanks...


No - the outside temperature will not shut the AC down.
You say the outlet has power? Does it have the needed 220 volts? Most of the time 220 volts is on one switch, (that operates both 110 volt legs of power at the same time). - but sometimes each leg is on a separate breaker and if "one leg" trips you will still have power at the outlet (110 volts) but you won't have the needed 220 volts. While this is not likely - it is possible - so I would want to test the outlet with a voltage tester and determine the voltage. You might try checking in your breaker box and seeing if another breaker (110volt) is tripped. The same thing applies if you are dealing with fuses instead of breakers - determine the voltage at the outlet - and if you don't have 220 and only have 110 then look for a blown fuse or as I said above - a breaker tripped.
If you do have 220 at the outlet and nothing is running - I would be looking for an inline fuse of some sort within in the unit. Many of the newer units have them and they are usually easy to spot and all you have to do is to unscrew the fuse holder and replace the blown fuse. Be sure to have the power off when handling fuses.
Note: Be aware that while breakers/fuses can trip and blow without a serious problem going on - they (blown fuses/tripped breakers) are usually a sign of something significantly wrong with the unit.
Good Luck!

I AM GETTING ELECTRICITY TO THE 220 PLUG AND THROUGH THE 220 PLUG WIRE TO THE STOVE JUNCTION BOX. THE STOVE TOP AND OVEN HEATING ELEMENTS ARE NOT HEATING UP BUT THE INDICATOR LIGHTS FOR BOTH ELEMENTS SHOW...


The indicator lights operate on 120 volts whereas the elements operate on 220 volts.
Using an electrical test meter go between the two hot legs and see if you are getting 220 volts. If not you have an open or non completed circuit.
Do not test from one leg to ground as you will probably read 120 volts for each leg. By reading across both legs you should get 220 volts.

Sir,it's an unusual problem..isometimes my lappy doesn't start ,even it don't show the hp logo screen just mute hot key keep on lighting ,,if sometimes it boots the windows xp then even it hangs wherever...


The troubleshooting section for your system is here:

http://h20000.www2.hp.com/bizsupport/TechSupport/SupportTaskIndex.jsp?lang=en&cc=us&prodTypeId=321957&prodSeriesId=1839143&taskId=110
The number of light flashes will narrow the defect to a section, for example, 4 flashes is video.

Software problems can be varied and multiple.

The hardware parts easiest for an individual to fix are RAM, Battery and Hard-drive. If you have a small screwdriver, and are willing, you may solve a hardware problem through elimination.

1.) Hard reset: Unplug the AC, remove the battery, press the power button for about 45 seconds to drain any residual charge. leave out the battery, plug in the AC and attempt to start. Make note of any error messages or differences. If the battery were shorted, this would solve the problem.
[If you have an internet connection , and another working PC, videos for repairing your HP model are available here]
http://h20464.www2.hp.com/resultsCSR.htm?prodSeriesId=1839143&MEID=D20132AC-5C2B-424F-93E0-91812FB94472

2.) if the problem persists: With the battery removed and the AC disconnected: Remove the RAM cover. Carefully remove the first RAM chip, set aside. Plug in AC and see if the system is okay now. If not, turn off and unplug, remove other RAM module, and replace with the first. Start.
This may have reduced your problem to a RAM module.
If not, and the system still is not showing the setup screen: try the hard-drive.
3.) With battery removed and AV disconnected: Using small screwdriver, remove the small screw(s)s holding the hard-drive cover (the cover will have an icon showing multiple stacked disks). with the cover removed, the hard-drive will be fastened with 2 or 3 screws, depending on model. Carefully pull out the HD and place in a safe location. With the AC reconnected, power the system and note any differences. Are you consistently getting the startup screen? Can you enter Setup?

Your problem description suggests the startup has been erratic and unpredictable. This is often power or memory. If you can consistently get past the startup screen, but it hangs when loading the operating system, this is likely a problem with the HD or the software setup. If you have a spare laptop HD, you can swap and install your bare operating system on this HD to eliminate the HD and Operating System as the problem.

If your Compaq as is it was from the factory, it has a restore partition to restore the operating system to the factory setup. If you can get the system started, you can restore individual parts of your system. otherwise, you may have to do a complete restore (F11 on Startup).

Troubleshooting is a logical process of elimination, looking for the simplest (and hopefully least expensive) solution first.

I have repaired many HP and Compaq systems. The HP site is very helpful with troubleshooting suggestions and even videos. If you have the patience, a few tools, another working PC and an Internet connection, you can solve 95% of PC problems.

Good luck. If you find this helpful, please accept this as a solution.

The dryer will not turn on. I know I have power because the light is on. But nothing happens when I hit start


Check for a tripped circuit breaker (a ganged double breaker), sometimes only one breaker trips without tripping the other. Switch breakers off and then back on. If you have access to a voltmeter, check for 220 volts AC at the the two slanted slots in the dryer socket. Occasionally, one breaker of the pair will fail internally--replace the pair. If 220 volts is present, then problem is internal to the dryer. Usually, it is a short circuit in the heating element which causes the circuit breaker trip.

Motor starter is tripping the breaker


this problem has to be solved by process of elimination first make sure the voltage used is the correct voltage the next step is to disconnect the motor wires from the starter and turn on the power if the starter engages u have a bad motor if breaker trips starter or power cable is shorted a direct on line 220 volts rated at 20 amps motor starter will work just fine or contactor and overload relay at 20 amps 220 volts ( GE, allan bradly,merlin gerin,legrand are some brand manufactures
