Run HP Stream7 Windows10 Tablet Without a Battery

* Zero Electronics Knowledge - Please Use at Your Own Risk! Worked for me but may blow you up along with your device :) Goodluck!

I'll try to keep this as short and quick as possible. If you have an Android tablet check out my other instructable shoudl hopefully work for you, I did not combine the two instructables caus although they sound pretty much similar they didnt work the same way as I expected. I have a HP Stream 7 Tablet that has a failing battery that cant hold charge even when plugged in. But I love it caus its running a full windows 10 install. So instead of dumping it into my drawer for eternity since I dont plan on buying a replacement battery - here's what I did to get it working normally again.Basically I tricked the tablet into thinking its getting its power from the battery. I removed the battery and soldiered an ordinary USB wire directly to the battery terminals & it booted up as it normally would. I'am sure youll find tons of cool instructional videos on what you can do with an always powered on Windows Tablet - especially since you have the micro USB charging port now free and unused, probably connect a USB hub with different USB accessories or connect a HDD& run a low powered low end nas -endless possibilities!

**any one with adequate technical knowledge please leave you expertise in the comments for the safety of everyone - the original battery output was 3.7v = 3000mAh & the original HP usb adapter that I am using is 5v=2amp output. Dont know how much of a difference that makes now that am not using a battery.

Step 1: Cut the USB Charging Wire

Get rid of the Micro USB end.
Cut off the White & Green wires.
You only require the Red Power wire & the Black Ground wire.

Step 2: Remove the Battery & Solder the USB Wire to the Battery Connector Plate

Solder the Red wire to the Positive terminal of the battery connector plate - displayed as (B+)
Solder the Black wire to the Negative terminal of the battery connector plate - displayed as (B-)

I used some hot glue as insulation and to hold the solder points in place (know it looks shady but its workable)

Step 3: Plug the USB Wire Into the HP Stream 7 Adapter & Startup!

Thats about it. It should start up as normal. Shutdown is like any other desktop or laptop running without a battery. So you no more can use it as a portable tablet. Have'nt tried plugging it into a powerbank though yet now that it has a USB wire attached, as I have no need to have it portable anymore, but that could always be an option.

I initially did try to connect it directly to the charger port without the battery inside before doing all these steps but the Stream 7 somehow misses the presence of the battery inside and does not start up.

I did however manage to successfully start-up my generic android tablet that way. There are instructions on youtube that show you how to startup an android phone without a battery - it work for my android tablet though that had a failed battery and thats pretty cool! Will post those pictures too later.
