    NECRO plugging computers into ungrounded outlet - what's the worst that could happen?

    Safety ground is about shorting a connection (fault) to utility AC hot wires so that a circuit breaker will trip - to disconnect utility AC power - to protect human life. Static electricity is charges in a human body connected to charges found beneath feet. A connection maybe down an arm...

    Which UPS is better ?

    Many know that a surge protector must not be plugged into a UPS. But many do not know why. A UPS in battery backup is typically not as 'clean' as they would have you believe. For example this 120 volt pure sine wave UPS outputs 200 volt square waves with a spike of up to 270 volts. That is...

    Is it possible for a power surge to come through your ethernet cable...

    Toughness is defined by numbers. An electronic power supply should withstand voltages as high as 600 volts without damage. That was a standard before PCs existed. Today's electronics are often tougher. Ethernet (for low current signals) is more robust; will withstand 2000 volts without...

    Is it possible for a power surge to come through your ethernet cable...

    Little to no relationship exists between words protector and protection. Any protector that would 'block' or 'absorb' a surge is bogus. Especially true of adjacent power strips or that UPS. Those only claim to protect from surges that are routinely converted by your computer's PSU into rock...

    House Power and Outlet question.

    Another example of the underlying principles. Code is only about human safety. It says nothing about appliance safety or reliable operation. That 'browned' neutral wire is not a human safety issue since it would not cause a fire. Our electricians stopped using backstab connections only years...

    House Power and Outlet question.

    That can be detected even using a $6 multi-meter and some robust appliance such as an electric heater, iron, vacuum cleaner, etc. Known is a ballpark distance back to a breaker box and the wire's gauge. A voltage difference appears between neutral and safety ground when a major appliance is...

    House Power and Outlet question.

    If a receptacle connection is firm (using screws; not a backstab method), then sanding was unnecessary. Backstab type connections can be problematic for computers. Ground only exists to protect human life. It has no useful function for hardware protection. If an appliance plug has a third...

    House Power and Outlet question.

    When we built an early 1960s home, all wire was BX. BX to three prong receptacles (ie kitchen) had a ground wire included. Other BX (ie that connected to bedrooms) had no internal ground wire. So those receptacles could only be two prong. Those had to be two prong because that BX connection...

    House Power and Outlet question.

    GFCI is how to get human safety without any safety ground. Safety ground is also called equipment ground. It is completely different from earth ground. Effective protectors work by connecting tens of thousands of amps on a low impedance (ie less than 10 feet) wire to earth ground. Then...

    House Power and Outlet question.

    Because an outlet tester reports some wiring faults, that means it always reports wiring as good.? Of course not. I said it will report some wiring faults. But can also miss other wiring faults. That means it cannot report a receptacle as good. Electricity is different at both ends of a...

    House Power and Outlet question.

    If a receptacle is wired defectively (ie if neutral and safety ground prongs are connected together), then a surge protector will claim it is grounded, a UPS will indicate no wiring fault, and the outlet checker will claim the receptacle is good. Any yet the receptacle is clearly wired...

    House Power and Outlet question.

    Existence of safety ground has no affect on a UPS or PC. That safety ground exists for human protection. It does nothing for transistor (ie surge) protection. It would not cause a shutdown. Does that safety ground exist? Many will rewire receptacles using same uninformed reasoning that made...

    Weird power on thing

    Get a meter, request instructions. spend minutes executing those instructions. Then (and only then) are every question answered. Then learn how a computer really works. Instead, you want to attack another because you ignored directions in one sentence and wasted time with a Kill-A-Watt. One...

    Weird power on thing

    None of that was relevant. Not even remotely relevant. Stated quite clearly was what is required. You ignored all that to discuss something irrelevant. Extracted was only what your numbers reported. Interesting that computer assemblers are told to buy PSUs that are double what is required...

    Weird power on thing

    Many computer assemblers have no idea how electricity works. Therefore have no idea how to select a PSU. Help lines do not want to teach how electricity works. So we tell computer assembler to obtain a PSU twice the needed wattage. Your numbers demonstrate intentional oversizing. Even your...

    Weird power on thing

    PSU powers off or on when ordered by a power controller. With power on, that controller decides if power is stable. Then either powers off or permits the CPU to execute. BIOS obviously is completely irrelevant since BIOS is ignored until the CPU is permitted to execute. That only happens...

    Fireproof vs non-fireproof surge protectors

    Fire has long been a problem when MOVs are grossly undersized. Two failure modes exist - degradation and catastrophic failure. MOV manufacturers are blunt about this. Catastrophic failure must never happen. MOVs must be properly sized to conduct any surge without catastrophic failure. An...

    Power strip causing boot errors.

    A meter is so ubiquitous as to sell in most any store that also sells hammers - often for less money than a hammer. Also found in other stores including Walmart for $14 or Harbor Freight for $5. If one cannot use a meter, then starting a car must be virtually impossible. A meter is that...

    Power strip causing boot errors.

    Symptoms are classic of a corrupted BIOS due to insufficient battery power. BIOS settings remain intact. But one or two bits change (ie a correction bit). Then BIOS is restored by checking BIOS settings. Your symptoms are classic of a weak battery. This is where thinking varies from knowing...

    Power strip causing boot errors.

    So BIOS setting are corrupted. BIOS has two power sources. The always powered on supply from AC mains and a battery. If both are removed, then BIOS is corrupted? So why is the battery not providing power. Maybe a battery or something else. Always see a problem before fixing it. Measure...

    Loose plugs

    Plugs are designed right. But many consumers only select on price - not on product information. A plug is designed for so many 'makes and breaks'. A standard bedroom plug maintains one 'make and break' maybe once every so many years. A kitchen plug has many more. So that plug is more...

    Anyone know where a safe all metal surge strip exists?

    Then you want an all metal surge protector that does effective surge protection. That has numbers that actually claim that protection. Is necessary to even protect power strip protectors. And that costs much less. Safest power strip is one without protector parts. Since those undersized...

    RTC and CMOS memory consume so little power that battery life expectancy is defined almost entirely by battery shelf life. That is same years - whether in a computer or stored on a shelf. Shelf life does not change whether a computer has AC power or not. Numbers in a next paragraph...

    ethernet over powerline not working

    Drop (and electric meter) must go only to one Main panel. That panel must have a mains circuit breaker. If the breaker is two poles (connected by a common bar), then the restaurant is two phase. If the common bar connects to three poles, then incoming power is three phase. That information...

    ethernet over powerline not working

    Please learn why CMOS batteries, once only good for five years, are now often rated for 10 years. CMOS consumes so little battery power that the CMOS life expectancy is called 'shelf life'. That battery discharges after more than five years whether inside a computer or on a shelf due to...

    If the computer is powered, then BIOS has power from the +5VSB wire. If failure occurred as he suggested, then the motherboard is defective by design. CMOS batteries are tested best with a meter. Swapping parts without first observing a defect is shotgunning; replacing good parts until...

    Why was it necessary to pass a law to provide broadband? DSL (2000 kbs) was developed and demonstrated in 1981 (when modems were only 1.2k). Massive internet backbone had been installed in the late 1980s and early 1990 in anticipation that DSL and other broadband technologies would be...

    Most computer consume mostly closer to 100 watts. And only peak at 350 watts. Watts is a mostly useless number. Some supplies are even at less strain when near highest load. Greatest strain can even be a 700 watts supply only providing 350 watts. But since that strain is completely...

    So I ended up buying a cable modem...

    You keep thinking in terms of blocking or stopping a surge. A safety grounded power supply is not earthed - and is completely irrelevant to hardware protection. That third prong is a safety ground to protect humans; not transistors. Again, protection is always about where hundreds of...
