Ill from LED on T430...Need a laptop that can handle Windows 10...

Hi OrcaLady91.

While I understand how light can impact us I'm not sure your strategy is going to work. While the processor speed and memory may handle Windows 10 at some point I believe the hardware and its drivers will come back to haunt you. Check any vendor site for any model that old and there will be limited to no support. Not saying it won't work but I'm sure issues will slowly develop as Windows 10 matures.

Now I don't know how you use your laptop in that some people have laptops and use them as desk tops, they basically stay in one place. If this might be you, have you considered getting an external LCD screen and keyboard. Then you could set your laptop to operate with the lid closed. This config may not be anything you want, just an idea.

I would also look into your existing screen settings. Tone the brightness way down to get rid of that hot blue white.

You could also try a product like f.lux which I install on all my clients machines.

This product has a lot of nice features and you can go with a warmer white. I've never tried to set it for all day warmer white but it has a lot of options. One really nice thing about this product, it is free.

Windows 10 also has a Night light option but again I've never set to 24 hours.

Others will have different opinions.

You are going to have a really hard time. I would personally go see a eye specialist to look into why you are having so many issues with certain displays. Also talk to a neurologist, who may be able to also work with finding out why certain light waves and refresh rates are giving you Migraines. You are not the only one that deals with these kind of problems.

Even just backlighting behind your laptop and putting in say 6500k/higher LUM bulbs into the lights in the room that you normally use your laptop in.

I use a 3-way 6500k CFL in the lamp next to me. I only turn it to the second notch and have to turn the brightness down on my Macbook, because of dealing with it causing me to have issues after a bit, since I have lenses in after I had Cataracts removed.

Maybe a surface would do?? A good way would be to go to say a Best Buy and test them all out..

Thanks. I don't think so. Need as much shielding as possible, so the more surface area, the better. Need something w/ a wifi antenna that's only tuned to 2.4 GHz. When I downgraded the card on the ThinkPad, the 802.11g protocol didn't work well. It's hard to find a laptop w/ the processing power & memory to handle Windows 10, without the dirty electricity from dual-band wifi. I'll call Best Buy, nonetheless. Again, thank you for your suggestions. :)

If you can find a monitor that meets your needs, you could simply hook it up to any PC (including your recently purchased used laptop) and use it instead of the built-in monitor. If that's a viable option, it will certainly expand your list of potential display choices.

Even a very old Dell can be made to run Windows 10, minimum 4GB ram, SSD, dual core running 2.1Ghz. Won't be gaming on it but browses very nicely and all the day to day Office tools work just fine. Mine is 10 years old.

The issue will be, one members opinion, the drivers will become more and more of an issue. Mine has driver issue with newer wireless card.

If you follow the threads here lots of people are experiencing video issues with the update to 1709. Sure they can fall back to older driver if they have it. You will also see some very experienced users who have tried to update older devices and just didn't make it because of drivers.

That was my concern with spending on older gear. That said if you can't go external the technology is basically forcing your decision.

Lots of members here will be more than willing to help.
