how to take apart the prime
Hi
I was wondering how one would go about taking apart the prime because I stupidly tried to reset it with a pencil and got the tip stuck in it so now it sometimes randomly resets
Thanks

Then use the battery cover's notches to separate the upper and lower sides of the calculator without damaging them. The calculator comes with its own custom disassembly tool Smile

RE: how to take apart the prime
When I took off the screws the calculator was still stuck together
Is there like Glee or a tape strip that I need to soften with heat?
Thanks
And I'll try the battery cover trick

There's no adhesive, the two haves are held together with plastic clips. You need to work your way in (nails worked for me, blades or edged tools tend to leave a mark).

Hello,

I use a credit card angle to separate the 2 halfs... Works well...

RE: how to take apart the prime
I have opened my HP PRIME a while ago.
Use your nails or a plastic card or a appropriate plastic pry tool as used to open mobile devices, in order to separate the back cover.
