Lower emissions laptop

bonty
I have pretty bad electro hypersensitivity and was wondering if people knew about a laptop/s that are lower in emissions that might work for me. I know its all trial and error but I'm interested in what people are using and may get some ideas that might help me. I react pretty bad to the laptop screen and was told by an EMF consultant that this is caused by dirty electricity so hoping someone can help or give me ideas to try. Also looking at using a different operating system to Windows that could cause less symptoms such as Ubuntu and hope people could weigh on this as well. Thank you

I don't think "dirty electricity" is the culprit with laptop computers.... more likely you are reacting to the display, or the hard drive, or the power brick, or the wi-fi/Blutooth.  

I've had good luck with the Lenovo Thinkpad X2-- series... the X200 was the most tolerable of that series, but may be too old to run Windows 10 (might be fine with Linux, though).  My wife currently has an X250, which I think might be the last one with ethernet ports and VGA output for an external monitor (and runs Windows 10 fine).

Also, I've had better luck with SSD drives in laptops/PCs, so might be worth swapping one of those in.

Another possible culprit could be the gases released by the hard drive as it works, if it's not a solid state hard drive (although that might be off-topic here).

I don't have any laptop suggestions, unfortunately. I've only purchased one (it was a Compaq HP that I got at Walmart in 2009, and I don't recommend it). Other than that, I've only ever had very old laptops that my siblings gave me.

But, a sibling did give me an even older ThinkPad than Marc's (mine was a T60). I could see a newer one than mine being a good choice (but I'm probably not the best judge of that). Just make sure it's not too old. The T60 has a fluorescent backlight (so probably don't get one that old, even if wasn't bad for a fluorescent display). The X200 has an LED backlight, though, of course.

What do you know about your sensitivity, so far?

While you still have your old laptop, have you tried changing the refresh rate to see if it affects you any differently?

Oh, and I'm not sure about others, but if I mix LED and fluorescent lights, I have a worse reaction than to either independently. If your backlight is LED but your bulbs to light your house are CFLs, that might be something to evaluate. For me, personally, halogen and LED mix fairly well, but I avoid most other combinations. I'm not sure how other people react to that combination. It could be quite different than my experience.

If the display bothers you a lot (I'm not sure if it does), I might recommend a smaller screen size, too. I used to be more interested in the laptops with larger screens, but mostly just for the full keyboard that came with many of them. However, I would reconsider that and probably get a laptop with a smaller screen if I were to get a new one now. The 10-key pad isn't everything.

Hi Puff,
Thank you for your response and suggestions.
I just tried to change my refresh on the laptop and I can't as when I click on the change refresh rate it only comes up at 60 hertz, it has no other option to click on. I will try changing the refresh when I come across another laptop and hopefully I can change it.

I have noticed that I have a pretty bad health symptoms from my display on laptops and also monitors that I have tried before. I'm probably reacting to the internal components as well but I definitely have a problem with the screen, I have noticed this more than anything else. I also have EHS symptoms from internet modems (even ones with no wireless built inside), cat5 Ethernet cables and wifi. I don't use wifi anymore of course a lot of my problems seem to come from electrical devices with no wireless in them so probably sensitive to all the EMF/EMI but don't know which one more than the other. I have an autoimmune disease that has caused my EHS disease and I experience blood pressure drops, dizziness, migraines, cognitive impairment, memory problems and white pale skin. All these symptom's resolve gradually after I stop using electrical devices that are bothersome for me. I don't use this laptop much because it causes health problems and only use it to talk to people who I think might be able to help me.

I also have a strange problem with my internet browser, I react a lot worse with Chrome and firefox but internet explorer isn't as bad for some reason. It looks like some internet browser generate more EMF's/EMI than others. I'm going to try and set up a low EMI cable modem and use fibre optic cables to connect to laptop/computer to see if this resolves the problem. I'm currently not using a low emf internet connection as I haven't come up with a solution as yet. I don't know which modem to use that is good for EHS disease and also don't know how to tackle the converters for the fibre optical cables as they have EMF's/EMI as well. Maybe have them run with a USB connection somehow or find an engineer to build me a linear power supply to run them off? I may also end up having the cable modem modified to run on linear power supply to remove most of the EMFs from it and set it up in a room away from me.

If I can't resolve the firefox/chrome issue I will be looking at trying a TV as a monitor or a modified projector but I definitely want to try a fibre optical internet connection and see if this resolves the problem first. I could maybe also use a program/operating system that makes the computer run on lower power. I read that people are using Linux/ubuntu  and have less symptoms but don't know which browser for the internet is good for an EHS person. I know people on here have the opposite problem to me, they can't use internet explorer but do well with firefox/chrome so not sure if someone can help but I thought I would give it a go anyway. If anyone knows how to resolve the firefox/chrome problem please let me know as I actually can't use it, not even for five minutes. I'm using Internet explorer currently.

Also thank you Marc Martin for your suggestions, I appreciate the help :)

Also to answer your suggestions about light bulbs, I'm not sure what I have in the ceiling I don't use them often and don't buy them. I will have to check.

I will look at a smaller screen size, thank you for telling me this. I'm open to trying computer monitors if I can't find a tolerable laptop. Also may end up using an LCD TV as a monitor or a modified projector if I have no luck with a laptop/monitor set up. Wondering whether to try a LCD display panel (small wattage) and have it run on a linear power supply?

I was told by an engineer that if you have symptoms coming from the screen the main problem is the switching mode power supply causing EMFs'/EMI to radiate through the screen and should be replaced with a linear power supply but I would say that other parts of the computer would be contributing to the EMF problem as well.

Symptoms from the screen could be coming from the DC->AC inverter if using a fluorescent backlight, or pulse width modulated (PWM) dimming if using an LED backlight.  My LED monitor is PWM-free, which I do find to make a difference.

Yes, I think a lot of displays only have 60hz as a choice.  You'd probably have to specifically look for that capability when purchasing a monitor to get anything else.

I know that Chrome creates a lot of different processes so it can take up a lot of memory (RAM).  So it would be bad if your computer has insufficient RAM to deal with that, and it has to offload RAM to the hard drive.  So probably make sure you have at least 16GB of RAM (if running 64-bit Windows)

> I don't know which modem to use that is good for EHS disease

Your modem choices are usually limited by what your internet provider supports.  That's why I like my Comcast cable internet -- lots of modems to choose from.  :-)

Hi Bonty, you obviously did your homework :)

Marc's suggestion of adding more RAM to avoid over-using the hard drive is a very good one.  You could also switch to an SSD, or even install Ubuntu onto a 64 GB memory stick and keep your existing Windows installation as a backup.  (In the latter case you'll need to turn off "snapshots" when you install Ubuntu. Otherwise it will fill up your USB stick with backups.)

By the way, it's actually not that hard to set up a linear power supply for a fiber media converter. Casper posted some pics and an explanation here:

http://es-forum.com/where-to-go-any-ideas-td4034304i20.html

Those media converters were great when I used them, but they weren't very durable for me.  You might have better results.

LCD monitors usually have a second switching power supply inside that powers the backlight, and it's not easy to replace.  How comfortable are you working on these things?

That's interesting with the memory (RAM) I will definitely be trying a laptop with at least 16 GB of ram and see if it makes a difference. It wouldn't surprise me if the laptop was working extra hard to run chrome and causing more EMF's. Also will try and get a laptop that allows me to change to a higher refresh rate and see if it makes a difference. I might also try your Benq monitor GW2870H Marc as I think the light is a contributing factor from reading your post.  I'm currently using a Toshiba Satellite L850 and it says online the backlight is a LED one so the PWM dimming might be a problem.

Thank you Karl for helping me out here. I will print out the pages from the link  you gave me and study it. Sounds like its best to try a monitor/screen that is PWM free and see how that goes. I am open to trying things, the LCD monitors I have tried have been pretty uncomfortable so far but I haven't tried many of them and haven't tried PWM free ones. I have never tried using an LCD panel on its own as a computer monitor so I don't know how I would go. I do prefer a laptop. The brightness of the monitor causes eye strain for me, I have turned the brightness down on the screen in the past but still uncomfortable from it (Not sure if this is related to EHS). I have never had this eye strain problem with laptop screens or my TV.
