Variable/Adjustable Voltage From Power Source & Question about Universal Chargers (w/ Images)

I ordered a used DVR recording box from ebay and the owner sent an incompatible used LAPTOP charger with it and says that it has worked for him without problems. (for how long I have no clue)

Pictures of the volt/amp specs on both Here: http://ift.tt/2xIOZMi

The Issue that I have is that the adaptor puts out 19v, but the DVR accepts only 6vdc

I'm aware of the fact that the Voltage provided by the power source may vary a little from the max output, but would it be dangerous either to myself or the device to run it with this large of a voltage (and possibly amperage) disparity?

Would this power brick even if its not from the same manufacturer only provide the exact about of draw needed to keep the device powered on but not push out more wattage than the DVR needs?

I guess I would just like to know if there's a high risk of breaking this device after a month because I know it will work for a little bit, but extended use is probably not recommended right?

Alternativelty I happent o have a universal 19.5v laptop charger which I know will provide the proper power to the device but would it work better than what was given to me or about the same?

So many more questions, but I want to stay focused so that I can get precise answers.

Thanks all for your knowledge and expertise!

certain keys on my keyboard dont work when "cold"

Hi guys, i have a Lenovo Y520-15IKBN (80WK) and certain keys on the keyboard don't work (e,g,h,8,9,Fn...) but only when the weather is cold. for example in the winter it used to work after certain amount of time when i first boot the laptop and stops working when i stop using it for a while, but now that the weather is hot it works just fine except for the first couple of minutes or when its colder. of course i do realise that it has nothing to do with the outside weather but with the temperature of the computer itself. can someone explain to me why this is happening and how it should be fixed as i cannot take it to the tech service until july even though it's still under warranty because i need it for school. ps: an external keyboard works fine.

Old PC with a Foxconn n15235 motherboard needs drivers! Help!!

So my Pc corrupted and I had to fresh install windows on it, but now its missing 3 drivers and one of them is for the Ethernet controller! I've tried searching everywhere for the windows 7 drivers but all I seem to find are some dodgey programs saying they will install it for me. Problem is without the ethernet driver I can't bloody connect to the internet. I've been using a USB to try get some drivers on there, but they just end up being useless programmes . I'm also a bit of a noob at these things, I don't understand where to find the names of things in my PC, I've opened it up but I don't understand whats significant and what isnt. If someone has the drivers and can teach me how to install them I'd be very appreciative! Submitted April 29, 2018 at 02:47PM by darrilsteady https://ift.tt/2r76xMZ
