B lank/Black Screen - After 10 minutes of idle your desktop or laptop goes blank screen. Sometimes 5 minutes of idle goes to blank screen. If it is your first time to experience this event happened to your laptop or desktop you might wonder why this event happen. This process called power management it has a default time frame when system is idle on a specific period of time it goes to standby mode or sometimes goes to sleep depending on the settings setup by your computer manufacturer. How many minutes does a laptop or desktop have before it goes to blank screen or standby mode? When you installed Windows 10 on your laptop, Windows 10 sets the time frame for 5 minutes, this setting is for power saver setting. This setting helps protect your battery life to last longer than usual operation. In desktop computer, Windows 10 sets the time frame to 10 minutes because desktop computers rely on AC power and not on battery.  Can we change or edit the power settings or optio...

Identifying audio chip sometimes is really difficult if we do not have the knowledge where to look for such information. Somehow, others find it easy to install or identify sound card driver for their computer. So, How are we going to identify our audio chip for us to download or install driver for our sound card.  There are ways to identify sound card or audio chip on our motherboard. The method below is for desktop computers. Method 1.  Identify the motherboard first.  From motherboard box. By identifying the motherboard, we can also easily identify its audio chip or sound card. So, how are we going to identify our motherboard? A new motherboard has already the brand and model number on its box and it also comes with CD/DVD software installer for its driver.  From motherboard labels (old desktop computers). For old desktop computers usually we open the chassis or casing then we look for the motherboard label or brand. The motherboard ...

Our computer desktop system requires fast hardware and uncluttered software if we want it to runs smoothly. Perhaps, we need to choose well in most of the time in order to maximize the performance of our desktop computer. Improving the system performance can increase our productivity on our desktop computer. Imagine if we calculate all of our time that we loss in our slow system it may reach days or even weeks if we add up all of this in one year. So, why should we change everything to new rather than upgrade or configure things? Not all the time we can spend our money in computer upgrades or buying the latest system. It is not a good idea to change your desktop computer all the time. There are disadvantages in buying new computer system like migrating your old files to new hard drive, keeping up to the new operating system, incomplete or no application installed. Printer or some old devices like Camera, Bluetooth are not yet installed in your new system. There is no point in buying t...

Good Day! Today I am going to show you may technique to diagnose and repair a hardware problem in a desktop computer. As we know if you are already an experience Tech or IT this will be easier for you to diagnose and repair a desktop computer. But if you are new or inexperience technician or IT this will be difficult for you to diagnose a hardware problem. So, how do we start? Below is an illustration of an old desktop CPU - Intel Pentium 4 with old IDE hard disk. Nowadays, Computer uses high speed processor such as Intel Core i3, i5, and i7 or Core i9. Also, uses SATA (Serial Advanced Technology Attachment) hard disk drive and SSD (Solid State Drive) on its motherboard. Both HDD and SSD use SATA port in the motherboard. First step. You must know if the problem is associated with hardware or software. Here is the list of most common hardware problems. 1. Desktop won't power on. 2. You can hear beeps from your computer. 3. No video ...

Hi everyone! Today's topic is about power supply again. I am going to tackle about this power supply problem because I want to share this knowledge I acquire from my experienced in repairing desktop computers. List of Power Supply Problems * Black Out or Dead Set. * Blown Power Supply Unit. * Power Supply Shuts Down After Few Seconds. * Noisy Power Supply. * Intermittent - Sometimes runs smoothly but most of the time cpu won't power up. * Black Out or Dead Set * This problem is the easiest to detect of all power supply problem. * Blown Power Supply Unit * This problem also is the same as black - out or dead set. Power supply does not produce any power because the fuse and other parts were blown. No current or voltage is passing in fuse. You could smell the burned parts from the back of the power supply. This problem in power supply could be repaired but you have to change many parts to reuse the power supply again. * Power Supply Shuts Down After Few...

      The most common mouse problems and where to look for these problems. If you are using PS2 or USB mouse the most common problems are both the same. They are usually related  to wire, but not all. Most people are throwing their defective mouse in two reason; one, they don't have time to spare to look for reasons why their mouse is not working properly. Two; they don't know how to fix their defective mouse. How to detect defective mouse? I know that most of us know how to identify defective mouse but not everyone. I have many encounters that the owner of the computer doesn't know what's wrong with their computer because the mouse is not working. In most cases if a mouse is not working we always conclude that the problem is the mouse itself but not most of the time. We should also consider that maybe the mouse is not the problem. First thing you should do is to transfer the mouse to a different usb port if you are using USB mouse. But, what if? you...

Did you encountered problem like this? This problem is likely to occur in desktop computers but not in laptops. This trouble is not usual to manifest in laptops. As, I have said this problem is unusual in laptops but possible will occur. So, today we will focus on desktop computers. If you encountered this problem in the future you will know how to fix it. So, I will start with on how to identify this problem. If you already encountered this kind of computer trouble you will know what I am talking about. When we start our computer, after few seconds computer turns off. In my experienced with this computer trouble 2-5 seconds computer turns off, then you have to turn it back on. And the same thing happens when powering it on, computer turns off. * What will be the possible part/s affected when this trouble happens? * a. Power Supply b. CPU Fan c. Motherboard d. Operating System All these parts are suspect when this problem happens. So, which part usually failing? If...

Identifying Power Supply for defect occasionally difficult for most typical user. But for some people with knowledge in technical is easy. For some that are new to repair or to this field. I think you must learn the basic of testing the power supply if it is working or not. During my earlier years in college we were not taught how to diagnose a power supply. I only learned this technique from a co-worker when I was already working. Most of tech person already knew this process. So, I am going to share this to you now. This process work well that you could easily determine if your power supply still work.  This applies to the computer that won't start. Let's pretend that you power on your computer but the system did not turn on. So, if you have already checked your AVR and UPS (uninterruptible power supply) unit if their lights were on. Also you have already checked every power cable if they were all mounted correctly. Then you get to the point that you...

We always asked "How to repair my keyboard?" or "How to fix defective keys on my keyboard?". Before, I was able to fix desktop and laptop keyboards. How did I done that? Okay! I am going to give you a hint on how did I done that.  But before we continue, please read the site policy . If you have already read this policy, continue reading this post. First disassembled it right? then look for the burned carbon resistor printed on the plastic board or circuit board if it is in an old keyboard model. Then look for a stranded wire about 3 to 5 times larger than your hair. You can also use the stranded wire from power supply. Tape it on the burned carbon printed lines on the plastic circuit board of your keyboard better if you use transparent tape. Check if all lines are connected or shunted using the stranded wire, then try it.  You can use my technique but this fix is not permanent. This shunt will burned some of new lines on your keyboard or some keys ...
