In some situations we will notice with a new pair of headphones with a “USB connector” that they are non-functional (in certain USB ports).
[mai mult...]Adding images with adjustable transparency percentage in MS Office
When inserting an image into a spreadsheet, we will notice that we cannot change its transparency from properties or without using a third-party application. Fortunately, a slight change in our approach is sufficient.
Maintenance and troubleshooting of mobile terminals’ applications’ functionality
In our daily use of smartphones we will notice that the correct functioning of (old) third-party applications is not always intuitive, sometimes even for experienced users; below we will detail several methods to ensure that they work (properly).
[mai mult...]External/secondary monitor not working (in Windows) – possible reasons
Usually, connecting an (external) monitor is a “plug and play” process and does not require any intervention or advanced knowledge, it is enough to assemble it and properly insert the power and data (video) cables. If we do not find ourselves in this situation, below I will list some possible reasons for the “out of the box” failure.
[mai mult...]The importance of increasing the sampling rate of monitored parameters
The situation may require the diagnosis of an unexpected behavior – in addition to using the appropriate tools, it is also important to perform monitoring at an appropriate time scale in order to avoid missing short-term behaviors.
[mai mult...]Another way to periodically view the current progress of bitlocker encryption
Although we have multiple means of tracking the Bitlocker encryption status, such as the progress bar that appears by default, or using the manage-bde-status command, we may note that the latter requires periodic use to find out the encryption percentage. A solution is to use a for loop with timeout in cmd.
[mai mult...]Free download of previous versions of Futuremark products
For various reasons, we may want to employ the well-known 3DMark or PCMark applications even if their versions are not updated; however they have guaranteed support for outdated platforms as well as the ability to configure test scenarios in an advanced way.
[mai mult...]Checking components’ performance using Passmark PerformanceTest
Even now we can still observe significant performance differences between systems having “apparently” similar components; an example of a tool that can help us determine the reasons for these differences is the “benchmarking” application (measuring work speed in predetermined tasks and generating a score based on it) offered by Passmark, PerformanceTest.
[mai mult...]Identificarea porturilor USB problematice folosind USB Treeview
Din motive legate de proiectarea perifericelor USB ori limitari impuse de catre componentele ce implementeaza conexiuni USB pe placa de baza vom intampina intreruperi sau disfunctionalitati pe anumite dispozitive.
De obicei acestea nu pot fi remediate din setarile UEFI/BIOS ori ale sistemului de operare (si nici prin actualizari). Daca nu se doreste identificarea unui port USB testandu-le pe toate, putem utiliza aplicatia USB treeview pentru a grabi procesul semnificativ.
[mai mult...]Dezactivarea functionalitatii IPv6 pe toate placile de retea (Windows)
In anumite situatii vom avea nevoie sa dezactivam din functionalitatile accesibile in meniul Properties al unui dispozitiv tip Network Adapter.
