    Wagner Steam Cleaner Handle Overheating

    The 2nd review on Amazon about 'A' wagner steamer says- "The handle got hot after using it for a short time. It was not uncomfortably hot, but close to it." Here Hot to some may be warm to others. Do you perhaps have a thermometer to measure the handle temperature?. I have seen these units with...

    How to connect piezo speakers to an amplifier

    That's the point of using a 'mosqito'. To annoy loitering youngsters while leaving adults alone. Some shopping malls have used this method. It is normally about 15kHz. Incidentally, I drive my teenagers nuts while charging Dewalt batteries. I can't hear it at all. Edit....I have a 'Function...

    Acer Aspire 4738 laptop intermittent shut off

    I think your HDD is failing. You should be able to hear it clicking. You may have encountered massive areas of bad sectors while scanning the drive?. OR You have virus/es that have corrupted the MBR again. Some software will also do this too. Your 64bit laptop will run 32bit software. You can...

    Can you identify this power switch?

    It might help if you gave us the make and model number of the machine. Most likely a proprietary component and not sold separately. But you can use almost any switch (same spec and ratings). However, you'll need to find a new home for the switch. Martin

    Acer Aspire 4738 laptop intermittent shut off

    Hi Michael, You say that you've been using the laptop for several years with no problems. Couple of questions to get me thinking.... Do you hear the fan when you turn the laptop on? (HDD connected). Does the fan continue running or slow down? (HDD connected). Same two questions with no HDD and...

    Acer Aspire 4738 laptop intermittent shut off

    Ok, so you seem to have ruled out software, HDD and ram. It does sound more like a thermal issue now. But having said that, there are a couple of other things to try first. Take the HDD out and turn on the laptop. It will more than likely say "no operating system" or similar. Leave it on and see...

    Mega not Atmega. It's a cheap LCR meter. Some are very good. They range from about £7 - £25. Amazon. I stand corrected. The Amazon link specifies Atmega chip. My units are Mega clones. Martin

    Acer Aspire 4738 laptop intermittent shut off

    Is this HDD identical with identical software and drivers? Cloned?. It needs to be. BSOD is hardware failure or software related. Mainly driver issues. Make sure you have the latest drivers. This will be difficult as Win 7 is no longer supported. So a WWW search for the latest that support Win...

    Electric motor on planer quits running after 1 minute

    Sounds like the motor is fine. When the belt is off the drum, the motor works. Can you spin the drum by hand easily?. It should spin freely. If it feels ‘grinding’ or sticky, the bearings need lubricating or replacement. Oil the bearings, fit the belt and spin it until it frees up. It should...

    Extending output cable of auto battery charger/maintainer

    Extending or replacing the wires wont affect it. You are only extending by about a metre (3'). Same for extending the mains input, some people will connect to an extension cord. Martin
