I've seen the vice-versa of it by using a hotspot but when use on mobile it asks for mobile data. Why can't it only share the wifi?

Hi, I am retired and work with computer programming as hobby. I wanted to find a way to connect a sensor to my laptop so that I could write a program for it. Example: reading atmospheric radiation levels with some type of sensor connected to my USB port. Could you direct me as to how, or...

Hey guys, From the title you probably get the idea about my question as I am so confused. How come a left click of a laptom Touchpad started to work normally after having a problem with it for more than a year? I really hope it is not a short therm thing, as I have no logical explanation for...

When I switched on my laptop yesterday, a window opened automatically with a name : "C:\Windows\system32\Cscript.exe". It now happens every time I restart my laptop. Is this because of some computer virus or should I just ignore it ? (My laptop is 5 years old and runs on Windows 7 ultimate 32...

Hi, My laptop is a Lenovo G450 and I use Windows 7. After I downloaded a Mp3, viruses just joined in my laptop. I saw unwanted ads in Google. I removed SeallePlus and DownSavve in the extensions but it keeps coming back. I use Symantec Endpoint System but it takes long to have a full scan...

Hi all, What laptop would you recommend for a mechanical engineering student? I really like Mac but I hear that engineering software is almost all Windows. Are there any good engineering laptops for around $1,000 that you could recommend?

Hello everyone, I am about to start college as an aerospace engineering major, and have a few questions regarding laptop GPUs and screens. First off, I am looking at the Dell XPS15, with the nvidia Geforce gt750m, and the alienware 15 with the nvidia gtx 980m. My main concern is that the...

Hello PF, I'm in the market for a new computer and due to my needs I've got it narrowed down to a laptop. My budget is about $1000, maybe a little more if need be. I'm looking for advice on what hardware specs would be most useful for the standard physics major. I run MATLAB, Maple, and a few...

Hello. Currently I'm in my third year of university. I would like to work in the field of observational astronomy (not so much theoretical astronomy). In about two weeks I'm going to buy a new laptop portable computer in the 2000€ range. Firstly I was thinking to buy a Microsoft Windows PC...

I wasn't sure where to place this question, but thought it might be a biological one and went with this folder. So, my parents were having this weird discussion the other day about using my laptop all the time in the dark. They think it's bad and sort of like reading a book in a dim lit...

My ancient Dell laptop used to work fine, but now I cannot access ethernet network we're on. It claims the speed is 1 Gbyte or 1 GHz too. I checked the connection by bringing in my MacBk Pro but that is not a viable option for this location. We have no "UT person" - it is roll your own. Any...

So, I'm going to be a physics major next year. I'm in the process of looking for my first laptop. I've been doing a lot of research and I've pretty much settled on a 13" retina display Mac book pro. My question is what guts do I need to be getting in the computer? I'm looking at 256GB SSD (I...

I've got a Lenovo y510p laptop, and I can hear the hard drive spinning up and spinning back down about once every 30 seconds to once every 2 minutes while I'm using the laptop normally. It's starting to drive me crazy and it's distracting. I'm wondering if this is affecting the lifetime of my...

I'm looking to purchase a laptop. I'll be using it as a portable means of using MatLab and doing some projects with Python and C and any other language I feel like learning at the time. Budget is 500 dollars. If I can get away with less I'd do it though. Less than 15 inches is preferred, I'm...

Hello, I'm a physics student (currently a senior in college, planning on going to graduate school for a Ph.D.). My current laptop is encountering major problems, mostly small things that make it not worth investing more money into the laptop, given that it's already old. I currently do...

For the past five years I have been successfully using a MacBook Pro. However, unfortunately, I spilled beer on my laptop about a week ago so the MacBook is no more. I don't really stay up to date on the advancements of computer hardware, so I was hoping somebody could suggest to me a good...

I have an older Win 7 laptop that I put it away for 2 months. I power it up lately, few things gone wrong. The computer said my battery died and have 0 charge even though I have it plugged in for over a day. Whenever I unplug the power, the computer just shut down completely. It's very hard...

Hello there! I am attempting to use a laptop keyboard I just salvaged from a spare. I noticed the laptop keyboard has a ribbon connection. Further research has told me that the ribbon cable essentially just sents signals to a processor attached to the motherboard. In other words, I cannot use it...

Mylar is an insulator, but it is coated with metal. Intuitively it should be possible to wrap a laptop in mylar and insulate the laptop from radio signals... but is there any chance it might affect magnetically the computer and/or its hard drive? I mean a very loose airy wrapping, like in...

Hi, When I’m studying for long hours and taking notes on my 24” IPS-panel, power-consuming PC-screen I often feel like my eyes dry out fast and sometimes my body feels ill. This happens much faster than if I read my chemistry/science books without my computer turned on. However I need something...
