Troubleshooting Tips For Laptop Owners When Your Laptop Suddenly Switch Off

It can be so annoying that at one moment you are sat there working on your laptop. Then without any warning everything on the screen just disappears and all you are left with is a blank screen! The laptop has mysteriously switched off.

Obviously the first thing that you are going to check are all your leads to make sure the power cable has not come loose and inadvertently shut down your laptop. If is not the case and your power adaptor is still plugged in correctly then the first thing to try is to unplug your adaptor and try to do a power cycle.

This may sound quite complicated but in effect it is quite easy to do. Step one is to unplug any power source linked to the laptop. After this you must disconnect any external devices that your have linked to your laptop.

Once you have completed those steps you need to remove your battery. After removing the battery from your laptop just press and hold your power button down.

It may sound a silly thing to do given that you have just taken out the battery but this does in fact work in a lot of cases. This is due to the fact that if you have been using a laptop for a while you could have some static build up in some of your internal elements of your laptop.

This in effect can make your laptop shut down by itself occasionally. This process may sometimes work when you lose an internet connection.

Once these steps have been completed you should check your power source and your battery separately. If the laptop works with the battery and not the power source the chances are that your power adaptor is faulty. If the laptop works with the power source but not just on the battery then you probably need a new battery.

Some laptops have warning lights for different errors. If this is the case with your laptop then you should just be able to check the user’s manual for any faults.

Network Troubleshooting Commands – You Should Know These

Network troubleshooting tools are a necessity for every network administrator. When getting started in the networking field, it is important to amass a number of tools that can be used to troubleshoot a variety of different network conditions.

While it is true that the use of specific tools can be subjective and at the discretion of the engineer, the selection of tools in this article has been made based on their generality and common use. This article reviews the top 10 basic tools that can help you troubleshoot most networking issues.

IPCONFIG. Short for Internet Protocol Configuration, ipconfig is used on windows to display the PCP/IP configuration such as IP Address, Subnet Mask, Default Gateway, DNS Server…

IPconfig is a troubleshooting command as well, as shown below

  • ipconfig /release is used to release the computer’s IP configuration, and prepares the network adapter to get a fresh TCP/IP address configuration.
  • ipconfig /renew allows the network adapter to get a new TCP/IP configuration.

PING. Short for Packet Internet Groper is used to test connectivity between two network devices. The host device sends an Internet Control Message Protocol, known as an ICMP Echo Request, the destination node then responds with an ICMP Echo Reply.

PING This IP address is used in conjunction with ping to test the loopback address on computers. The tool is very handy and would be the first to try when network issues ever occur. The IP is a class A address that has been a reserve for the purpose of testing that the network card and the TCP/IP stack work fine.

Traceroute or Tracert in windows is used to display the path taken by an IP packet, from the source to the destination computer.

TELNET (Telecommunication Network). It is a command used to access another computer remotely. Also known as a command request, is the most utilized by network administrators. A Telnet request may be accepted or rejected by remote computers; depending on the permission you have you may be prompt to enter a username and password. Example below:

Microsoft Telnet> o

( to )

Connecting To…

The above telnet command was used on Windows 7, and could be different on other operating systems. Telnet is not enabled by default on Windows 7 as it is on Windows XP, it has to be done through Control Panel.

Nslookup. Most used by network administrators, nslookup command is a tool used for DNS (Domain Name System) Testing and Troubleshooting. It is advisable to learn how DNS works before using this command. Example below:

C:UsersBerbo>nslookup “just for illustration”

Default Server:  SE572


Hostname. Used across a verity of platforms, the command is used to configure or find the name of a computer or other network device. An example below on windows:



ARP. Short for Address Resolution Protocol, ARP is used to find a MAC address or physical address when only the IP address is known. Example below:

C:UsersBerbo>arp -a

Interface: — 0xb

Internet Address      Physical Address      Type           00-01-e3-ef-69-b0     dynamic         ff-ff-ff-ff-ff-ff          static            01-00-5e-00-00-16     static

Troubleshooting When Your Computer Freeze (Lockup) Problems

How familiar does the following sound? Your computer was working fine, but then suddenly started locking up (aka hanging or freezing), rebooting itself (crashing), or shutting down spontaneously? If you know only too well what I am talking about, then read on! Performing the simple steps below can fix the majority of lockup cases.

1. Check for recently installed software or hardware.

If the lockups started to happen after you installed a new piece of hardware, new software programs, or new drivers, uninstall it and see if the problem goes away.

2. Run your antivirus program.

One of the first things to do in the case of sudden lockups is to run your antivirus program. Check your antivirus manufacturer’s website for updates and the latest virus definition files. (This is absolutely necessary, outdated antivirus is not going to be of any use!) If you don’t have antivirus software installed – or if updates are unavailable – run one of the web-based antiviruses scans that some major antivirus vendors like Trend Micro are offering for free. You can find a comprehensive list of available web-based scans and free antivirus programs on

3. Run some good spyware removal tool.

If your machine is not infected with any viruses, it is still possible that it has some harmful adware or spyware is present. Download and run some good spyware removal tool such as AdAware or Microsoft AntiSpyware. Check for a list of free spyware removal applications.

4. Check for free hard drive space.

When no viruses are found, check out free hard drive space on drive C:. Make sure there is more than 20% of free space available; low disk space can lead to random lockups.

5. Check for overheating.

Overheating is another known cause of lockups. It can be caused by problems with fans inside the case, dust buildup, or other cooling problems. Make sure the power supply fan and CPU fan are running and free of dust buildup. You can check the temperatures inside the case by running Motherboard monitor – make sure the temperatures are within the preset limits. Be very careful while cleaning inside the computer case (use plastic vacuum crevice tool) and NEVER OPEN THE POWER SUPPLY CASE as it contains high voltage.

6. Check the hard disk.

Check the hard disk – it is possible that its logical structure is corrupted. To check the disk for errors, right-click on the disk C: icon in “My Computer”, select the “Tools” tab, check all checkboxes in the “Check disk options” field, and press the “Check now” button. It should ask whether you want to schedule the check next time you restart your computer – answer “Yes” and restart your PC. The check will be performed automatically after startup; it can take a while, so be patient. The program will attempt to fix some problems automatically – however, if the hard disk is failing physically, it will need to be replaced. It is also a good idea to run Disk Defragmenter (located in Start Menu > Programs > Accessories > System Tools) to optimize data placement on the hard disk for increased performance and reliability.

7. Check the memory.

Sometimes random lockups can be attributed to computer memory (RAM) starting to fail. You can test the memory by running Windows Memory Diagnostic that can be downloaded from If memory problems are found, try re-seating the RAM (pull it out and plug it back in). If it doesn’t work, replace the defective RAM.

8. Check for other hardware problems (advanced users).

More hardware-related problems can be diagnosed by running hardware tests from the Ultimate Boot CD that can be downloaded from However, you should only use it if you know what are you doing – some programs on that CD can be dangerous when used inappropriately (for example, some of them can wipe the contents of your hard disk).

9. Update Windows and drivers.

Some lockups can be caused by outdated software components – update your windows and drives by running a windows update: (it’s a good idea to run it regularly).

The above steps will help diagnose and eliminate the most common causes of lockups. Hundreds more of other possible scenarios need to be dealt with on a case-by-case basis, as it all goes down to your particular computer configuration. Asking on PC troubleshooting forums/newsgroups should help you figure out solutions to not-so-obvious lockup cases.

A Guide to Troubleshooting Smart Devices and The Internet of Things

You can’t open a magazine, got a web site, or attend an event these days without hearing the term Internet of Things or IoT. Seems like today everything can or should be connected. Nice idea, but what does it mean if you’re thinking about security?

Open standards
To start, you should know that any kind of IP-based video surveillance and physical access control devices such as security cameras and door controllers are in fact IoT devices (in fact, we invented what many call the first IoT device 20 years ago when we launched our first network camera, but that’s another story). These connected devices offer non-proprietary and open standards allowing users to integrate them with other devices and software as they wish and without restrictions.

The further adoption of IoT will drive this integration beyond currently separate device categories. There is a huge opportunity to manage multiple systems with just one management console. From smoke and gas sensors to video surveillance, physical access control, loudspeakers, air conditioning, and heating, escalators, and elevators to window shades, light switches, and automatic doors – all these devices can be managed together with the IoT.
Internet of Security Things.

From a security standpoint, IoT is more than just cameras. For example, Axis introduced what is best described as an IoT loudspeaker in March of 2015. It can be integrated with just about anything. You can even assign it a phone number and make announcements through making respective calls to that number.

A quick primer on how something like that works: it is a self-contained loudspeaker that offers signal transmission, decoding, amplification, microphone, and speaker all in one unit. Unlike analog loudspeakers, there is no need for a separate amplifier. An external power supply is also not required, thanks to Power over Ethernet (PoE) support. It can, therefore, be very flexibly installed as an extension to existing security systems allowing operators to deter unwanted activity without having to send a security guard to the scene, for example.

This is just one example of a new breed of security products. We are seeing the beginning of what is probably best named the “Internet of Security Things.” Open standards will allow previously separate device categories to be used together and accessed via a single management console. This will make security systems easier to use while providing better situational awareness and overviews of incidents.

Step 1 – Google

If you are encountering a problem, odds are the answer can be found using a search engine. Start here first!

Step 2 – Look for Clues on the Device Itself

Many smart devices will have flashing lights or other indicators when something goes wrong. This can provide clues to what is going on.

Step 3 – Check the App for the Device

Most smart devices have a corresponding app for a smartphone. This app can usually detect when the device is malfunctioning and give you tips to restore functionality.

Step 4 – Turn It Off and On Again

Yes, this may seem cliché, but turning your device off and on again may fix the issue! It only takes a minute or two, so you might as well give it a try.

Step 5 – Check the Power Source

If your smart device would not turn off and on, there’s probably something wrong with the power source. Make sure the device is really getting power, either from a battery or power cord.

Step 6 – Dig Out the Instruction Manual

If you still have the instruction manual for the product, now would be a good time to get it out. There’s usually a helpful troubleshooting section near the back. The instruction manual will contain information on how to reset the device, too.

Step 7 – Check your Wi-Fi Connection

If your device connects to Wi-Fi, make sure your Wi-Fi router is working. You can easily test this by seeing if other devices connect to the Wi-Fi. Try going to some different websites as a test. If your Wi-Fi isn’t working, try unplugging the router and plugging it back in.

If that doesn’t help, connect your computer to the wall with an ethernet cord. If you still can’t access the internet through the ethernet cord, contact your internet service provider.

Step 8 – Reset the Device

If nothing has worked, you can try to reset the device back to factory default settings.

Caution! This will remove all your settings and should only be done as a last resort. You will need to go through the device set up process all over again.

If you have the instruction manual, it should say how to reset the device. If you don’t have the instruction manual, search the internet for the factory reset process.

Step 9 – Contact the Experts

If you have tried every single one of these steps to no avail, it’s time to bring in the experts. There may be a hardware issue with your smart device. Check the device manufacturer’s website for help with warranties and repairs.
