Check your Laptop/Netbook/notebook/Ultra portable Computer’s battery healthy easily

After reading this guide, you will be able to check how healthy your computer battery is. When the computer is new it gives you good battery backup. But, as it gets old the backup goes considerably less than it used to be.

To Check the current status of your battery now, you can use a built-in utility in Windows 7 to check the health of your battery.

  • Make Sure your charger is plugged in
  • Go to Start Menu
  • In the Start Search box type CMD
  • Right Click CMD and click Run as Administrator
  • Type powercfg –energy in the opened windows ( Command Prompt )
  • Windows will run a trace on your battery for 60 second and then save a report in your root drive Example: C:\energy-report.html
  • You can then double click the HTML file to open it with your web browser and read the report.
  • This report explains Errors, warnings etc.
  • To know the current charge capacity and health status, scroll down to the section that reads battery information
  • Here, see Design Capacity
  • Now, see the Last Full Charge Capacity
  • If, Both the numbers in Design Capacity & Last Full Charge differ a lot, let’s say for example the Design Capacity was 6500 & Last full charge is 2500. Your battery is not in a healthy state and is not holding most of the charge capacity it was designed for.
  • This would be the proper time to order a replacement battery.

Fix : Windows : No sound problem in Windows 7 , Vista , XP

There can be a number of reasons if your computer doesn’t play any sound at all. Sounds include Windows basic sounds, music etc.

What to Check:

  • Sound Hardware is present or not
  • Device Drivers are installed or not
  • Speakers/Headphones wires are connected properly
  • Check if mute button is pressed
  • Sound/Audio Hardware is Enabled from BIOS

Sound Hardware/ Sound Card:

Sound Hardware is commonly known as sound card. If you have a desktop system & have installed a add-on sound card for high performing sound, the first step would be to open the cabinet and check if the sound card is installed into the slot properly.

If you have a laptop ( notebook/netbook/ultra book), there are very slight chances that you have a Add-on Sound card installed.

To Check the sound card from within windows:

Go to Device Manager,

To open Device Manager:

Control panel –> small icons –> Device Manager,
type device manager directly into the start menu search box ( Windows 7 only ) 

See the below screenshot and check if the sound, video & game controllers shows your Audio hardware installed.

device manager


To Check if Device Drivers are Installed or not

If you see a Exclamation mark on any listed hardware or see a yellow question mark saying other devices, it is quite possible that either the device drivers that are installed for your device are faulty or there are no drivers installed.

To resolve, right click the hardware listed either in other devices or with an exclamation mark & click on update drivers & let Windows search the Windows Update service for any new drivers that might be available for your device type.

You can also visit your computer manufacturers support website & try downloading the drivers from there. * refer your computer documentation.

If you see no hardware present within the sound, video & game controllers, you should try pressing the Scan for hardware changes button just below help ( refer screenshot above). If there is no response from the device manager after refreshing you might be facing a hardware issue or Your Audio Hardware might be disabled from your BIOS options. ( To enable/ check BIOS settings go to the end of this page).

To Check if Speakers/Headphone wires are connected properly

There is no special guide relevant for this, but if you really don’t know how to check a loose connection, follow the wires connecting your computer to your speakers/headphones and vice-versa. Tighten if loose.

Check if the wires are plugged into correct slot

if you are using a desktop PC, see the image below and confirm all the wires are plugged into the right slot.

sound back panel desktop

Also, check for faulty speakers/Headphones.

Check if the mute button is pressed

Sometimes a hotkey or otherwise the mute key gets activated and we just don’t pay attention to the muted volume button in the taskbar. refer images below





If you see the muted icon in your taskbar click on it to unmute. Also check the volume level and increase if necessary.

Check if Sound/Audio Hardware is Enabled from BIOS

To do this, refer your motherboard/system maintenance manual & looks for things given below:

  • Press Del or F2 or F10 or any other key depending on your system type & make
  • Advanced Options/ Integrated Peripherals
  • Enable Onboard Audio/ AC’97/HD Audio
  • Enable it
  • F10 ( Save & Exit )

Block Internet Access over Network but allow Network Access / File & Print Sharing in Windows 8 , 7 , Vista , XP

After reading this guide you will be able to block internet access over a home network or any network that your are an administrator to. This guide is a very simple collection of steps that do not require any additional software or firewall support to block internet access & just allow file & printer sharing.

There are situations where one needs to allow or block internet usage to some users over a network. There are different methods that can be used to do the same, though the most easy method is given below:

Let’s assume that you have a network running with single or multiple routers, either in home or office & you wish to block just the internet access to specific and / or all users. For this you have to login to your router by either IP address or router address & provide your username & password therein. Now in DHCP or DNS setting just uncheck the automatic DNS & mention the DNS settings to be anything you wish. for example: or anything you like except the router’s IP address. 

Now all the computer systems over your network might still show the internet to be connected but will not resolve / open any websites.

To enable network access in a specific computer, just go the properties of the network adapter of that specific computer & within the IP address menu mention any open DNS. i.e or Google DNS would also do.


And that is all there is to it.
