Daca mouse-ul, tastatura sau majoritatea tipurilor de periferice cu butoane incep sa prezinte disfunctionalitati (precum dublu click la o singura apasare), putem utiliza aplicatii precum autohotkey pentru a inlatura defectiunile partial sau complet.
[mai mult...]O metoda de vizualizare a valorii frecventelor orizontale si verticale de reimprospatare a imaginii in Windows
Daca avem nevoie de setarea unei rezolutii cu anumiti parametri (sau frecvente foarte specifice) si vrem sa ne asiguram ca acestea sunt aplicate, nu ne putem baza intotdeauna pe valorile raportate de windows sau de driverul video. De asemenea, acestea de obicei nu furnizeaza detalii precise despre parametrii rezolutiei actuale.
[mai mult...]Multi-function printer – paper feed blockage message during scans after cleaning
When using the tray/automatic paper pick-up system for scanning, it will be noticed that sometimes the paper remains blocked. In these cases, the MFP displays an error message and recommends opening an access hatch specific to the need to remove the jammed papers. After performing the intervention and closing the hatch, the message will disappear, but this does not always happen.
[mai mult...]Considerente pentru testarea exhaustiva a stabilitatii supratactarii memoriei ram
Pentru impartirea kiturilor de memorii ram in functie de performantele acestora, producatorii supun chipurile de memorie unor teste conform standardelor de interes (precum cele oferite de jedec). Suplimentar, producatorii pot oferi profile implicite pentru supratactarea (frecventelor) memoriilor RAM, valori ce pot fi de asemenea re-crescute de catre utilizatori.
Uneori chiar si supratactarea oferita de producator va produce instabilitate in sistem (de la coruperea datelor, BIOSului pana la blue-screens sau regresiuni de performanta). In continuare vom vedea o serie de variabile ce sunt de obicei ignorate, dar impacteaza aceste rezultate.
Configuring a USB mouse/peripheral with proprietary software without direct installation of its software
For various reasons we may find ourselves in a situation where we do not want to install the proprietary software provided by the manufacturers of the USB devices in use, since usually these can negatively impact the behavior of the operating system or cannot be completely uninstalled. Fortunately VMWare comes to our aid with a solution, as their application can “forward” complete control over a USB device to the guest machine so that we can configure it.
To implement the solution we will assume that we have a virtual machine with windows already installed.
Interogarea si compunerea informatiilor din winver folosind windows powershell
Instrumentul winver ne arata licenta de windows folosita, versiunea sistemului de operare impreuna cu utilizatorul si organizatia catre care a fost licentiat produsul; daca dorim sa preluam aceste informatii in format text (deoarece nu se pot copia informatiile din fereastra generata de winver), putem utiliza powershell (ca administrator) in acest sens.
[mai mult...]Cursor not working in certain areas of the screen in fullscreen applications
After making certain types of changes (such as resolution changes that involve a prompt from Windows to correct the scaling factor) we will notice that a Windows restart is necessary to fix the cursor’s behaviour. Even in fullscreen applications, when it leaves a certain perimeter, it loses focus and becomes unusable until it returns to said perimeter. The behavior is due to bugs in the procedure for completely returning the OS to the scaling factor in use before applying the changes.
[mai mult...]Asteptari asupra numarului de PCI Express lanes raportat la porturile populate pe placile de baza AMD/Intel X64 cu chipseturi din clasa consumer
Dorim sa evitam reducerea semnificativa a performantelor datorate utilizarii necorespunzatoare a latimii de banda disponibile pe porturile PCI Express de pe placile de baza cu chipseturi din gama consumer (non-enterprise) – in acest scop este esential sa verificam impartirea lane-urilor PCI-Express la fiecare placa de baza in parte.
[mai mult...]Non-functional “usb” headphones *in certain ports
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.
