Monitor went black screen for a second whenever other big home appliances starts/stop.

[mrchow19910319]

I have been experiencing this for a while,.

I live in a relatively old house. 

Whenever my air conditioner/ fridge's motor kicks in, the monitor went black for a bit. 

Then it went back on. 

 

How can I prevent this kind of thing to damage my laptop/ desktop? 

The monitor already went through a RMA because of this issue. Dell swapped me a new one. 

Now it starts to happen again. 

 

I think I do have a fuse in the house electronic circuit. And I cannot do any sort of remodel whatsoever. Cos I only rented this apartment. 

The hose is quite old, I think it was because the circuit cannot take on too many things at once. Or the power isn't stable enough. 

 

Can I buy a UPS just to add some sort of buffer in between? Could it prevent damage to my system caused by unstable power? 

This monitor issue did caused me a motherboard (in my laptop). I don't want to damage it, as well as other things connected to it.

Depends on the UPS, but most likely yes.

I have two, well my Router is on the other side of the house.

 

Two things to look for, max Wattage of the UPS. and how long it will last at your idle use and full power use, if your using it just to for power stability, just make sure it has enough wattage.

Can I connect my laptop's power supply to it too??? That monitor fried my laptop's mobo a few months ago... 

 

then how do I calculate the wattage I need? 

Monitor watt+desktop watt + wifi router watt + laptop watt?

For example this lineup goes from 420W to 820Watts, Just pick what ya need. I would go Max Desktop Wattage too, not idle. 

 

I think under MAX load it's 10-15 Minutes. Idle probbly closer to an hour ithink.

Could you recommend a brand for me? I am not sure which is good... 

Also did you experience this kind of issue before and a UPS solved your problem?

I have not, my power is fairly stable. 

CyberPower and APC are two good brands I have used.

Worst case, you return it if problem isn't solved, but a UPS is always good to have anyway.

Okay. I see. 

 

Another thing is lets say that my desktop's power supply is 450Watt, but I am pretty sure that during normal usage it is about 300+ watt, so I need to go with 450 Watt anyway just to be safe?

Is it still related to the power fluctuations?, or just randomly?

Still related to power fluctuation. Same scenarios. Air conditioner kicks up, screen goes black.

If, a UPS doesn't solve it, try a differnet outlet, if that doesn't work......

That's all i got.

Tried it,. Connect it to another outlet at the other side of room/.

NOthing changed. 

 

Also I think I will unplug the connector of my air conditioner and give it another shot. 

Fuck this man, annoying af.
