Sounds like there was a short circuit in the unit. Do not use until properly serviced by a technician.

Grinder motor: AC DC


If it was a DC motor it wouldn't run on AC. If it hasn't been used for a long while it might smell while the dust and grease burn also the bearing(s) could be dry, make sure it turns freely and smoothly and nothing gets too hot. Check current with ammeter

Switched on my dyson dc 14, but suddenly started to splutter, smell of burning, i switched it off and now it wont switch back on. i have changed the fuse.


Burning smell is NOT good. Sounds like an electrical short in the motor field windings. You'll have to take the machine apart to locate where the damage occurred and see what can possibly be repaired or needs to be replaced.

Presario laptop issue with power indicator light and detecting powers supply


Sounds like your DC Power Jack is bad or broken. The DC Power Jack is where the power cord plugs into the laptop? Most times it get damaged by too much stress on it such as sitting in bed with the laptop, or putting the laptop in the laptop bag with the power cord still plugged in.

Take an ink pen and put it into where the Power Cord normally plugs into the laptop. If the pin inside the DC Jack is loose or wiggles then the jack is probably bad. Sometimes the jack can be completely burned out and you can smell smoke .

If the internal DC Power Jack is loose, you will have totake the laptop apart to repair it. The DC Power Jack is on themotherboard and most times it is soldered to the motherboard. That meansyou will have to desolder the old one and solder a new one in it's place. Sometimes the dc power jack sits in a slot between the bottom case and palmrestwhich hold it in place and has a cable harness that plugs into the motherboard.

My Eee 4g surf netbook won't charge at all. Upon turning it on, it runs for a second, then shuts off due to a lack of battery power. The charge cable's light is also not turning, so that may


I think your DC Power Jack is bad. The DC Power Jack is where the power cord plugs into the laptop. If it is bad, then a good power cord cannot charge the battery, nor can the laptop turn on once the battery is drained.

You say it smelled burnt, that might mean it took a power surge. I always tell people that before your plug the power cord into the electrical outlet on the wall to remove the other end of the cord from the laptop. That way if you get a power surge you will only damage the power cord and not the dc power jack or motherboard.

Anyway, take an ink pen and push it into the dc power jack and see if there is some movement. The little pin or the casing of the jack should not wiggle.

The DC Jack is soldered onto the motherboard. To replace it you will have to take the laptop apart, desolder the old dc jack and solder a new jack onto the board. Sometimes the DC Jack sits in a slot rather than being soldered. The palmrest and bottom case helps to keep it in place. This type of DC Jack usually has a cable harness that plugs into the motherboard.

Dc jack of labtop getting vey hot


A common weak spot on most laptops is the DC power jack. If someone trips on the wire while you have the power adaptor plugged into your laptop, chances are that the power jack will get damaged.
On most laptops the DC power jack is soldered directly to the motherboard and there are only three or four small pins holding it in place. Unfortunately that makes the power jack quite weak. Any sideways pulling of the DC power cord while attached to the laptop will usually dislodge at least one of these pins, breaking the solder around it. Modern laptops use quite a lot of power, from about 70W to 120W or even more. The bad electrical connection from the dislodged pin will cause sparks and heating that will eventually burn a hole through the motherboard and can even be a fire hazard.

The usual signs of that are:
  • The battery is not charging properly or stays at half charge despite that you have been using the power adaptor.
  • The screen flickers (the brightness is changing) while the power cord is plugged in. This is caused by the laptop switching between DC power (screen is brighter) and battery power (screen is dimmer).
  • The DC plug gets hot after a few minutes of use and may even smell of burning.
  • There are "scratching" sounds coming from the DC jack.
You need to take the unit apart and check/resolder the DC jack on the system board.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

I have a bull frog spa with two flo-master pumps, specifically Emerson extreme- e model number r23mwdma-175. Spa is noisy and had made a burning smell. Is this a motor, impelled, or other problem? My...


Common sources for a burning smell in order of most likely, depending on how your spa was equipped, in my opinion would be:

Blower motor - Worn out brushes on a DC motor arc heavily and will give off an odor.
Heater - Elements build up scale over time with less than ideal water chemistry and will give off an odor when heating.
Pump - As a pump nears total failure it can overheat enough to begin to burn the winding insulation and tie down cords causing a burning smell.
Control box/electronics - least likely but a failing relay or GFI recepticle can also burn and eventually fail.

The light can come in a box with just the light alone (light with battery), single ac(light with ac cord and 1 charger), single dc(light with dc volt cigarette outlet and 1 charger), double (light, 1 ac, 1 dc cord, 2 chargers) pb charger...and so on. The sticker on the box that contains the UPC code should have the listed detail on what the box should contain. Still confused check out the website www.streamlight.com search the light you're looking for and check out the product part number list. Hope that helps ;)

check the power cord itself, if you see on the back side of the cord a burnt or blackened spot then the cord is the issue
