Memory is Detected but is not Configurable Dell Poweredge Server

Memory is Detected but is not Configurable Dell Poweredge Server

This happens to our two Dell Poweredge R230 servers running as domain controllers. Almost everytime we restart the server for windows updates, the server will not restart and there is an error message on the display “memory is detected but is not configurable”.
This has become a big problem as we are mostly accessing the server remotely. When domain controllers are not running, users will not able to be authenticated thus they cannot access network. Access points are not working and our handheld wireless scanners also not working and this has become a nightmare because it means our production stop working and bad for business.
The other unpleasant condition is when there is long electricity blackout which UPS battery cannot handle, the servers went off but cannot back up because of this problem.
We are using original memory from Dell, so there is no chance that this is a compatibility issue. After searching on the net we found there is a new firmware that will fix this issue. The latest firmware is version 2.1.4 while our current version is 1.0.2

Steps to upgrade firmware to resolve “Memory is Detected but is not Configurable” issue.

1. Need domain administrator password to run this update.

poweredge r330 an error was detected during memory initialization
2. Firmware validation.

File sometimes corrupted when downloaded, this process below make sure that the firmware file is intact.

poweredge t130 an error was detected during memory initialization
3. Confirmation before upgrading the firmware

Make sure that the version is newer than your current version.

memory initialization warning detected

4. Reboot several times after upgrade

dell openmanage memory is detected but is not configurable

 

 
After reboot confirmation dialog, your server will restart several times during the process. This is normal, expect 5-10 minutes in this process and it will finally finish and the server back online without issue cannot restart anymore.
Have a nice day 🙂
Not Connected to The Internet Resolved by Upgrading D-LINK DIR-600M Home Router’s Firmware

Not Connected to The Internet Resolved by Upgrading D-LINK DIR-600M Home Router’s Firmware

My home internet is using D-LINK DIR-600M router. This router has 4 ethernet ports for client, 1 ethernet port connected to fiber optic modem (or any other modem) and wireless connections for laptop and mobile devices.

There is 1 annoying problem with this router, sometimes my wireless clients cannot get in to the internet although it still connected to the router’s wireless network. When this is happen I disabled and enabled wireless connection and this works fine.  Although this is fine with me but not for other family members, they don’t know how to disable and enable wireless, they have to restart the computer when this is happen and this is not good at all.

One that I can do to resolve this problem is to upgrade it’s firmware. I already looking for firmware for my router DLINK DIR-600M but it’s not easy. There is not much result on search engine.

After browse through all search engine result from position number 1, I decided to download it from Softpedia. The file is 1.23MB and contain 1 pdf file and the firmware image itself. Here step to upgrade the firmware:
1. Using only cable to the router, don’t use WIFI.
2. Extract the file to the folder where you can find it easily, I extract to desktop.

3. Login to your router, the default IP address is 192.168.0.1

4. Login using administrator account, username is Admin and without password (blank).
5. Make sure current firmware version is lower than you want to upgrade. In my case the current version is 3.01
6. Click Maintenance tab, Firmware Upgrade, Click choose file and browse  to file DIR-600M C1_v3.05ENB01_beta_20170306.img

7. Click upload it takes only several seconds and the upgrade process finish. The router will restart in 60 seconds.

8. I forgot to save the router’s configuration, luckily the configuration still there not change, this is good, some router will reset it’s configuration after firmware upgrade.
In case you need the file, I put it here https://drive.google.com/open?id=0B3BPcME1ZlDtN2Rreks0SUlibms
After firmware upgrade I never found the same problem again.

What Is A QWERTY Keyboard?

What Is A QWERTY Keyboard?

What is a QWERTY keyboard? – You’ve probably asked yourself, “What is a Qwerty keyboard?” and wondered why people still use it today. This article will explain how it works, the advantages it has over other keyboards, and why people still prefer it. You’ll also learn how to use a Qwerty keyboard to write your own articles or make presentations. Read on to find out! But first, let’s examine the history of the keyboard.

Who Invented The QWERTY Keyboard?

The QWERTY keyboard layout is a common keyboard design for Latin script alphabets. The design was based on the Sholes and Glidden typewriter layout and sold to E. Remington and Sons in 1873. The layout has been a popular choice for many years, and was first used on a typewriter sold in the U.S. in 1909. The QWERTY keyboard layout is often referred to as the “standard” keyboard layout.

The QWERTY keyboard layout was first developed in the 1860s by Christopher Latham Sholes and his business partners, Samuel W. Soule and Carlos Glidden. The Q key was positioned in the corner, making the most commonly used letters easy to find. The vowels were close together to prevent jamming. A modern QWERTY keyboard has a number pad located on top. A Q key in the corner allows you to press the letters you want to write more easily.

Its layout

The QWERTY keyboard layout is a standard design for typewriters using Latin-script alphabets. This layout was based on the Sholes and Glidden typewriter design, which was sold to E. Remington and Sons in 1873. Today, it is the most popular typewriter layout used worldwide. Its design was adapted by a number of different companies to meet the demands of the typing public.

The QWERTY layout was originally invented for typewriters in the 1870s, by Christopher Sholes. The first six letters of the alphabetical line – A, Q, R, T, and Y – are the basis for the layout. Sholes redesigned the typewriter’s keyboard to prevent letter jams. Early typewriters jammed frequently when adjacent letters were pressed at the same time. The QWERTY layout focuses on spacing the letters so that they are not in close proximity to each other.

Its uses

The QWERTY keyboard layout is one of the most widely used computer keyboards. Its layout puts commonly used letters in easily accessible places to make typing easier. The QWERTY keyboard was adapted from a typewriter. Because typewriters were mechanically slow, it was important to separate commonly used letters to prevent jamming. In 1873, Sholes and Glidden sold the layout to E. Remington and Sons. In 1878, the company released the Remington No. 2 typewriter, which popularised the QWERTY keyboard layout. Since then, the QWERTY layout has been widely used and has become the standard for typing.

The QWERTY keyboard was originally designed for English language use. In many countries, accents are not used on the standard US keyboard layout. Some countries, such as Canada, have adopted a different keyboard layout. For example, the French keyboard uses a different layout. The standard US keyboard layout on MacOS includes “US-International” keyboard mapping. Similarly, most PC keyboards in Europe have the AltGr key, which replaces the right Alt key and allows the user to type most common diacritics in the region where the keyboard was sold.

Its disadvantages

There are some downsides to using a Qwerty keyboard, but overall, it is the most commonly used keyboard. Many people feel comfortable using it, and the lack of difficulty in learning a new keyboard makes it a good choice for many users. In addition, Qwerty keyboards can get some tasks done well, and some typists even have high word per minute scores. But there are also some downsides to using a Qwerty keyboard.

One major drawback to using the QWERTY keyboard is its infrequent use of the home row, the column of letters beginning with the letter A and ending with the letter L. Because the home row is naturally where your fingers rest, you rarely type on it. In fact, Dvorak’s simplified keyboard estimates that you use it for less than 20 percent of the time. Because it is not ergonomically sound, QWERTY has some serious disadvantages.

Its alternatives

If you’re looking to switch keyboard layouts for your computer, you may be wondering whether the QWERTY keyboard and its alternatives are the best choice. In addition to the ergonomic benefits of these alternatives, they also pose some challenges for productivity. Here’s a look at the differences between QWERTY and Dvorak. Ultimately, which layout is best for you depends on your specific needs and preferences. But whether QWERTY is better or worse for your productivity depends on the type of tasks you do.

Although there are a number of alternative keyboard layouts, the QWERTY layout is still the most common. People who need to type faster may find it difficult to adjust to other layouts and must invest time to learn a new keyboard. While Dvorak’s layout is widely accepted, it requires some effort to learn. Using this keyboard layout can make you faster than you would with QWERTY. However, if you have a preference for Dvorak, you may want to give it a try today.

How Laptop Screens Are Measured?

How Laptop Screens Are Measured?

How laptop screens are measured – Laptops display commonly range from 11.6 to 17 inches. Some people like game players love a bigger screen (17 inches) and other comfortable with 13 inches display, usually top management that want a smaller and lighter laptops.

Desktop computer monitors are offered in sizes ranging from 13 to 43 inches. Some users may employ a TV as a monitor, with screen sizes of 84 inches or more. While technology plays a part, generally speaking, the greater the monitor size, the higher the cost.

For desktops and laptops, the monitor or screen is measured from the top left-corner to the bottom-right corner, in inches.

Measurement of the screen on the laptop
Physically measuring the screen of a laptop computer allows for the determination of the display’s dimensions. To take a measurement using a tape, begin at the top-left corner and pull the tape in a diagonal direction until you reach the bottom-right corner. Be sure to simply measure the screen and leave the bezel, which is the plastic edge that surrounds the screen, out of your calculations.

Screen of the laptop measurement – a look at the specifications
The dimensions of the display on a laptop are typically listed among its technical specs. Check the specifications of the laptop to see if there is a part that is named “Screen,” “Display,” or something similar. In that particular section, the screen size is specified using inches. If you are still confused, you can find the dimensions of the laptop by doing a quick search online using the model number.

Knowing the monitor size of a desktop computer by measuring
Physically measuring the screen of a desktop computer monitor is the only way to determine the monitor’s dimensions. To take a measurement using a tape, begin at the top-left corner and pull the tape in a diagonal direction until you reach the bottom-right corner. Be sure to simply measure the screen and leave the bezel, which is the plastic edge that surrounds the screen, out of your calculations.

Knowing the monitor size by looking at the model number
The dimensions of the screen are indicated by the model number of the monitor, which includes those dimensions. For instance, the model number S201HL could be assigned to an Acer screen that measures 20 inches. The size of the monitor is indicated by the “20” that comes after the “S.” A model number will typically begin with one or two letters, then be followed by a series of numbers. The size of the monitor is often denoted by the first two numbers that follow the letters in the model number. If you are still unclear, all you need to do is do a quick search online using the model number to obtain the specific dimensions.

Besides the screen size, refresh rate also important for the display to make a better picture, and movements, especially for gamers and animators. Commonly is 60hz for refresh rate but in high end laptop is has 144hz refresh rate.

Conclusion:

The bigger the laptop screen usually identic with higher resolution which is good because it make the picture smoother. You can measure the laptop display and desktop monitor diagonally without measuring the plastic part.

 

144hz Laptop What Is So Special About It?

144hz Laptop What Is So Special About It?

144hz laptop – 144hz is a refresh rate that is used in many high end laptops. This rate is higher than what is typically used in laptops, which is 60hz.

What is a refresh rate?

Refresh rate is the number of times per second the display refreshes. It is measured in hertz (Hz) or kilohertz (kHz). Most LCDs use 60hz refresh rate, which is the standard refresh rate for most laptops. The refresh rate determines how many times the screen can be updated in one second.

How does a higher refresh rate help?

A higher refresh rate helps with motion blur. Motion blur is when your eyes can’t see a fast moving object clearly because they are still.

Why would you want a 144hz display?

You’d be surprised at how much of a difference it makes. I’ve been using a 144hz monitor for the past year and it’s been great. You’ll notice the difference when watching movies, playing games, or even just surfing the web.

In fact, you might not even realize you’re on a 60hz display until you switch to a 144hz display.

I think it’s more about the ability to display smooth motion. When the refresh rate is lower, you get more jittery movement as the image is being refreshed. At higher refresh rates, there’s less jittery movement.

I have a 4K TV that has a refresh rate of 144 Hz, and it looks very good. I think the same applies to monitors.

When our eyes are comfortable with the display of the laptop we will be able to stay longer on any activities in front of a laptop.

How do I get a 144hz display?

The first thing you’ll need to do is check your laptop’s specifications. There should be a sticker on the bottom of the laptop that will tell you what the maximum refresh rate is.

You can also go to your local computer store and ask them about the highest refresh rate your laptop supports. They may have a list of laptops with the highest refresh rates.

How do I know what my current refresh rate is?

There are two ways to figure out what your current refresh rate is. One is to open up your laptop and look at the sticker on the bottom. The other is to download the DisplayFusion software from the official website. It’s free, but you’ll need to download it from the website https://www.displayfusion.com

Once you’ve downloaded and install the software, you’ll need to open it up and click on “Monitor configuration”

If you’re using Windows, you’ll see the refresh rate under the “Display” section.

The above picture shows 40hz refresh rate, but mostly it shows 60hz, I am not sure what causes this. When your laptop has 144hz refresh rate it will shows so.

The laptops that has 144hz display refresh rate is Alienware, and Acer Helios 500, these are gaming laptop that has all the necessary features to support your gaming activity. Like processor, memory, storage, display, keyboard and the colling system.

How To Check Computer Specs or Laptop For Upgrade Or Troubleshooting

How to check computer specs – Sometimes we need to check our laptop or desktop computer specification for upgrade or troubleshooting purposes. In this post, I am using windows 10 and some utilities that can be used on various operating systems.

For example:

  • To be able to buy the correct type of RAM we need to make sure what is the current installed RAM in the computer.
