Commitment to Quality
Data Integrity and Preservation
A top priority is to maintain clients' data. Computers can be replaced, while data often cannot be. I will not assume without checking first that clients already have a current backup of their data. In the event that re-installation is required and the client is unable to be consulted, their data will be backed up first. What constitutes "data" includes personal files, photos, media, etc. It does not include programs, which can be reinstalled. As a minimum, on Windows PCs, essentially everything from all active user directories will be backed up (normally found in C:\Users\). Attempts will be made to determine if the user has files in other locations or partitions which need to be backed up as well.
To avoid ESD (electrostactic discharge), I will use or perform any combination of the following before servicing hardware components: ground myself by touching the metal chasis or that which is appropriate to ground, wear an anti-static wrist strap, &/or use an anti-static mat.
When possible, I will avoid servicing internal components on carpeted floors. During on-site hardware servicing in which the client has carpeted floors, extra measures will be taken to maintain grounding (frequently touching the computer chasis or wearing an anti-static wrist strap).
Loose components with exposed circuitry will be stored or transported in anti-static bags.
Uninterruptible Power Supply
When available, during off-site servicing, UPS (Uninterruptible Power Supply) will be used when servicing computers which do not contain a battery (e.g. Laptops, Tablets, Smartphones, etc. are not applicable). This is to avoid possible data corruption or hard drive errors from developing due to possible power outages or temporary power fluctuations.
An Uninterruptible Power Supply (UPS) will be used when updating the BIOS to avoid BIOS corruption from occurring during power fluctuations or outages.
All devices serviced off-site, which require AC power, will use surge protection with proper grounding.
Replacement Power Adapters
Replacement power adapters will meet power requirements for given devices pertaining to voltage and amperage.
Only connectors which are designed to support hot-swapping (plugging in and unplugging while the system is turned on) may be hot-swapped. For all other cables, the system will be powered down before plugging or unplugging the device.
For circuitry cleaning (e.g. CPUs, contacts, etc.) only Isopropyl Rubbing Alcohol rated no less than 90% will be used or a cleaning solution appropriate for circuitry.
To avoid damage to computer screens (particularly LCDs, Laptops, Tablets, Smartphones; older CRTs are not applicable), only alcohol-free and ammonia-free cleaning solutions will be used with microfiber cleaning cloths.
During keyboard maintenance which requires the removal of keys (e.g. cleaning), removal of the keys will be tested on one or two keys first to ensure no breaking (some keys can have fragile parts which can snap off during removal). Should problems occur, removal of the keys will be ceased and an alternate (although less thorough) method of cleaning will be pursued.
Installations and Updates
Downloaded programs used for installations and updates will be obtained either from the official manufacturers' websites or from trusted sources. Any exceptions will be verified both via multiple safe website checks before downloading and scanned for malware before installation.
