Surface Pro 7 charger randomly stops working

I use the USB port on the side of the charging brick to charge my phone and headphones sometimes. I've never felt the brick get too hot but the USB port definitely charges much faster than using a regular USB and power brick into a 110V outlet. If yours gets very hot then it further adds to the inconsistencies in manufacturing of their charging bricks.

I've noticed that whether the charger is OEM from microsoft or aftermarket from 3rd party sellers, there is random, intermittent discontinuation of charging to the surface pro. From reading this thread, this issue ranges all the way from the Surface Pro 3 to the current Surface Pro 7 and I experience this issue as well. Microsoft initially told us to update the drivers and send in the laptops for "repair" but no solution is ever offered or and their repairs never worked as the problems always returned.

Their representatives on this forum completely gave up responding to posts in this thread complaining of the exact same issue. It's honestly disturbing that this is their way of handling consumer affairs. I went from losing faith in this company to flat out giving up on buying another microsoft product again.

I am wondering if anyone has anything charging from the usb port on the charger?

i have been able to use my charger for about 2 weeks now, the last couple of nights i have been plugging my headphones into the usb port on the power supply to charge while performing downloads on my surface. i have the power settings to while plugged in set to never and 20 on battery, i would wake each morning to find that the power supply did not work and my system had gone into hibernate. the usb charge port and the power going to the surface was gone and would only be restored by disconnecting the power from the outlet, waiting a few seconds, and plugging it back in. i also noticed that the power supply would get warm just charging the surface and get hot with the headphones plugged in. also the charger is 65w which is the exact same wattage as the most power efficient processors on the market. and there isnt any holes for cooling on the power supply. some people are complaining about degradation of performance after only a half a year of use.

i can only deduce that the power supply is either under wattage for the load an average user puts on it or there is inadequate cooling for the power supply leading to degradation of the components inside.

the only solutions i can think of would be to add heat sink fins to the outside of the power supply to aid in cooling or find a larger wattage power supply with active cooling.

do not modify the power supply yourself as it would void the warranty and could damage components.

Hello,

After reading all these people with the same problem it appears that this is a endemic problem with the SP7.

I have 4 different chargers and none work, but only at times, one or another might or might not work randomly. I have everything suggested without success. This indicates that the problem is with the SP7 - not the charger.

Why has MS not addressed this problem with a solution?

Do they not want us to buy another one?

My unit is still under guarantee -

Speak up MS - this is not a time to be silent - This wont go away. PPL do not have money to run around buying this and that because you are selling faulty equipment.

I AM WAITING TO HEAR FROM YOU!!! But I wont wait for much longer. There are many better and less expensive possibilities out there.

Fed up,

Philip.

I have the same problem. I have read all the suggestions and nothing works.

aren't ms obliged to supply a remedy? My sp7 is only 6 months old.

If so how do i proceed with that claim for a new charger if that is their remedy.
