The CMOS battery is usually a small lithium-ion battery similar to the ones that power wrist watches. It is located on your motherboard and provides electricity to hold certain configuration settings, including system time, even when the computer is completely powered down. The lifetime of this battery is roughly 10 years, but how long it actually lasts usually depends on how heavily the computer is used.
Most computers in a corporate environment receive thie time from a local or internet time server. This doesn’t mean that the local system time is unimportant. If the CMOS battery dies, not only will the system time be lost, so will other configuation settings your computer depends upon. A slow system clock is just the first sign of a dying CMOS battery.
Testing Ports with an Online Scanner
Testing the effectiveness or ineffectiveness of your firewall and other security procedures is vital in order to keep the network safe from outside attack. As an entry level PC support tech, you will not be expected to configure or monitor network security measures. Depending on the size of your organisation, that task will be performed by either a senior staff member of a security specialist.
However, you may occasionally be asked to test an individual computer or server’s security with an online port scanner. This is a utility provided for free by various security organisations and it can be very effective in detecting which port of a computer are vulnerable from the internet.
Searching For Drivers
Usually, you can find drivers for a particular device either on the CD that accompanied the device when it was purchased or online at the manufacturer’s web site. Occasionally you will encounter an older device that the manufacturer no longer supports or discover that the manufacturer has gone out of businesses. Now you are stuck trying to find drivers for this machine or unit. Much of the time though a compatible driver is stored somewhere on the hard drive – it’s just a matter of finding it. First you need to identify the correct driver – my tech support team has many of the correct drivers stored on portable hard drives that can easily be uploaded to your machine. Simply call for assistance. Don’t do it yourself – as many people have mistakenly used the wrong driver and sorting the mess it made of their hard drive was beyond my team’s capability, and I’d like to thank http://www.datlabsdatarecovery.co.uk/ for rectifying the problem !
