In some situations, you might need to reset the System Management Controller (SMC your computer)

I was advised to do this periodically as good 'household.

All advice appreciated.

Resetting the SMC is for troubleshooting. No maintenance.

Apple support page...

Before resetting the SMC

You should only do an SMC reset, after trying all the other standard troubleshooting. Try each of the following steps in this order before resetting the SMC. Test the issue after performing each step of troubleshooting to see if the problem persists.

  • Frequently, you will need to reset the router.

    I am running Windows 7 and have a Netgear N600 Wireless Dual Bank Gigabit router.  I am often "began" internet and have to reset the router.  I don't think it should happen, but have no idea what's going on or what to do about it.  Any help to solve the problem is most appreciated.

    It's your router or your ISP (Internet Service Provider).  Routers sometimes seem to "wear out" and must be replaced.  I had to replace a little once they got to have 3 or 4 years.  This has happened with Netgear and D-link and one I can't remember the brand.   I would check with the ISP well because you never know when they decided to do an interview without you say.  I've been running Windows 7 at home for 3 years and have learned that when I see trucks of the ISP in my area, I can often wait some disconnects.  I saw no problem with Internet I thought that Windows 7 related however.

    Good luck.

  • Need to reset the date and time

    My system has decided that it is Jan.4th 2004 and everytime I turn it on, I need to reset the date and time. How can I cure this?

    Packard Bell's Web site does not recognize the 'ALT' CO2 as a model.  Despite this, however, PB seems only to provide a 'generic user guide"which is not described the replacement of the motherboard or the battery at all.  In fact, the only thing he has to say about batteries is be careful how get rid you of them.

    Your computer is a laptop or Desktop/Tower computer?

    If you have a desktop/Tower computer, you can look here--> http://www.uktsupport.co.uk/pb/mb/pbmb.htm and see if you can identify the motherboard used in your computer.

    However, if you have a desktop/Tower computer, the best thing to do is to unplug your computer from the network and, taking the precautions perfectly static electricity, open the box and inspect the motherboard yourself.

    A newish mother on the above site, http://www.uktsupport.co.uk/pb/mb/cosmos.htm, shows the battery on the center line vertical and more to the left.  It's just below the 3 PCI slots.  If you have something like that, a Visual inspection should be enough to see how to remove it.  The type of battery will be engraved on the top of the battery.  In the photo, it looks like a model CR-2032, but there are several models of battery on this size.  Battery CR-2032 (or equivalent) is available in almost every pharmacy chain in the United States as well as online and stores like Radio Shack.

    The page for an old motherboard, http://www.uktsupport.co.uk/pb/mb/450.htm, indicates that the battery is a '3.0V DC Lithium soldered to the motherboard"and if that were the case, it would probably be something that you wouldn't do yourself.  However, this thread is to think that all you have to do for this particular mobo is actually finding the right type of support plug-and - battery.

    If you have a laptop, things can get quite a bit more difficult.  If you can find a different model for your computer name, you may be able to find the manual here--> http://tim.id.au/laptops/packardbell/ , but some of these manuals can not explain clearly how to get to the CMOS battery.

  • New Internet Service, do I need to reset the router E2500?

    I had used temporarily my router E2500 to work with a wireless broadband source by connecting it to a Cradlepoint CTR500.

    Now I will connect the E2500 to run (and ongoing) with Time Warner Roadrunner using a modem cable Scientific Atlanta WebSTAR DCP 2100. Given that I'm changing the source of the internet, do I need to reset the E2500 to factury default values, and then perform a new installation using the Cisco Connect software?

    The cable modem is currenlty connected via an ethernet straight cable to the PC. I had read that remove the ethernet connection and the cable from the cable modem and the modem powered off for 10 minutes will cause the modem to "forget" the PC's MAC address.  Once connect it MAC address of the PC had been "forgotten", the ethernet cable from the modem to the router, which make the modem pick up the router's MAC address and eliminate the need to clone the MAC address of the PC. Does this sound correct?

    Unplug the power to the modem cable for 30 seconds should be good enough. In regards to the router, you should be able to get without a reset, if it is set to DHCP for the type of internet connection.

  • You will need to connect the battery, but lapptop now sign showing that the battery is not connected, so does not load.

    You will need to connect the battery. until recently, all ok.  never use the laptop as a mobile, always on the wireless, but lapptop shows now sign that the battery is not connected so does not load.

    I have a laptop which, so far, is always connected wireless when it is in use. I want to take a vacation, and notice a signal arrives that the battery is not connected and therefore does not load.  This has happened recently, although the battery never showed a 100% charge. can someone tell me how to connect the battery please.

    Check that the battery is correctly installed. If it is then the problem is that the battery is exhausted, so you should buy a new battery.
