Samsung Galaxy S4 shuts off after a couple seconds

Posted by on October 11, 2018 No comments

I had this strange problem. I would insert battery into Samsung Galaxy S4 and it would turn on and then shuts off after couple seconds. After some research on Google I found the power button is stuck and pressed all the time – ON.

On a brand new phone you insert battery and then you have to press the power button to turn it on.

On a broken phone the phone will turn on after you insert the battery and because the button is pressed on all the time it will turn itself off again.

SOLUTION: take the phone and put it sideways where the power button is facing down on a table or some flat surface and don’t slam it! but lightly hit it maybe a couple of times and the button will come unstuck. The phone should turn on by itself but the button isn’t stuck so it will turn on perfectly fine.

Windows Surface PRO RT WiFi connection issue – Limited connectivity

I ended up using a registry hack to limit the Surface to 802.11g speeds

If you still have problems apply the following registry changes:
Open Desktop -> Search -> regedit
Open regedit. Select menu Edit -> Find…
Enter “AutoUse40Mhz” -> do search.
There are 2 such entries in registry. We need to change one, located under
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\” branch.
– Set “AutoUse40Mhz” to “0” (it has value “1” by default)(This limits the channel bandwidth to use 20MHz, this reduce the speed and it’s the recommended setting when you are experiencing issues with n connectivity)
– Set “Band” to “4” (it has value “6” by default)(for what I understand this change may force some devices to connect g)(I would recommend to apply the first registry change, reboot and see what happens before applying this other change).
