Integritatea datelor stocate pe SSD poate avea de suferit din motive termice, respectiv se poate dori o imbunatatire generala indirecta a performantei sistemului. In continuare vom prezenta o serie de masuri ce pot fi luate in acest sens.
[mai mult...]Several rare types of boot problems and their solutions
On certain systems we will notice that either after a Windows update, firmware update (or BIOS/UEFI), or performing maneuvers such as the long press of the start/stop button (methodology) we will end up being unable to boot on a perfectly functional system. Fortunately so far, these booting problems have been solvable, as it will be presented below.
[mai mult...]Extinderea timpului de folosire a perifericelor wireless (mouse) in scop educational
Un utilizator se poate afla in situatia de a nu putea sa reincarce sau sa inlocuiasca bateriile/acumulatorii de pe mouse-ul wireless. In acest caz sau pentru alte aplicatii, se pot urma o serie de pasi pentru maximizarea timpului de folosire si minimizarea consumului de energie electrica a dispozitivului.
Cititorul ar putea avea nevoie de o documentare suplimentara legata de termenii tehnici, specificatiile si modul de lucru al dispozitivelor pe usb.
[mai mult...]An alternative to TELNET for testing connectivity
If our situation requires the use of TELNET for connection testing, one solution is to employ Powershell.
[mai mult...]Folosirea unei setari de power plan din Windows poate reduce cu peste 10x timpii de incingere a procesorului
In scopul prelungirii duratei de viata a componentelor, respectiv a integritatii datelor este important sa reducem timpii petrecuti de componente la temperaturi crescute. Microsoft ne pune la dispozitie mai multe setari ce ne pot ajuta, dar din motive de scara temporala ne vom axa pe una anume: SYSTEM COOLING POLICY.
[mai mult...]Recommendations for improving wireless signal quality in Windows
Most wireless network cards come pre-configured to reach the maximum possible speeds according to the standards supported by each individual device. Unfortunately, these default settings are not always optimal and can lead to signal loss, having a significant impact on connection speeds and stability.
[mai mult...]Using the power button (on/off) for the purpose of various fixes
The on-off button (switch) present on all laptops/PCs/servers can be used for purposes other than power on/power off/sleep/hibernate/closing the screen (or other options made available through the operating system or integrated firmware). In general, the applicability of the following method also extends to other devices that employ ram memory (and capacitors), such as smartphones or printers.
Situations that can be fixed include, but are not limited to the following examples:
-non-functional laptop keyboard
-laptop keyboard that responds incorrectly or clumsily to pressed keys
-occasionally helps with BSOD fixes
-allows the detection of devices/peripherals/components that would otherwise not be recognized (including certain SSDs, in which case it is recommended to save the data on them and replace them with a model that does not show this symptom).
Cateva situatii de intrerupere a conexiunii la retea (rj-45)
Un utilizator poate observa ca paginile web incarc greoi, nu raspund la comenzi sau apar “offline” – uneori chiar si incercarile de listare la imprimanta esueaza, desi sistemul de operare nu raporteaza probleme cu placa de retea ori conexiunea. Toate acestea intamplandu-se desi la o inspectie vizuala initiala “totul pare in parametri ori corespunzator” pe traseul fizic intre statie si router ori switch etc.
[mai mult...]Preparing the main storage device in the case of non-detection by a customized windows installation kit
Due to the design limitations of the “BIOS” (UEFI) on certain devices, we will notice that sometimes we cannot install windows on a perfectly functional storage device. Next up we will detail how the situation can be easily fixed using diskpart.
[mai mult...]Demonstrarea tehnologiei de “lampa in regim stroboscopic” (rezultat similar monitoarelor cu tub catodic)
O data cu retragerea monitoarelor si televizoarelor folosind tehnologia tubului catodic s-a creat un vid pentru utilizatorii ce doreau posibilitatea de a vedea clar obiecte sau texte in miscare pe ecran, putand sa distinga informatiile chiar si la viteze mari. Din fericire de cel putin 10 ani a fost comercializat un inlocuitor (partial, dar foarte bun), si anume implementand “lampi stroboscopice” ce se pot opri si re-porni de 60 ori pe secunda (sau mai des). In continuare vom vedea cum se poate observa acest fenomen pe la modul demonstrativ pe orice dispozitiv cu ecran.
