Hi,

Download AutoHotkey, right-click on your desktop and click New -> AutoHotkey script. Insert the following.

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
#Warn ; Enable warnings to assist with detecting common errors.
#Persistent
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.

#Esc::
Sleep 1000
SendMessage 0x112, 0xF170, 2, , Program Manager
return
#Left::
send {Home}
return
#Right::
send {End}
return
#Up::
send {PgUp}
return
#Down::
send {PgDn}
return

Save it and double click the file. This will do the following while the script runs:

Win+ESC will turn off your screen.

Win+Left will work as Home button.

Win+Right will work as End button.

Win+Down will work as PgDown button.

Win+Up will work as PgUp button.

Edit the script and re-run it if you want to modify this behavior.

This is the exact part that I use, try this one and press win+ESC.

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
#Warn ; Enable warnings to assist with detecting common errors.
#Persistent
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.

#Esc::
Sleep 1000
SendMessage 0x112, 0xF170, 2, , Program Manager
return

Other useful scripts:

#Left::
send {Home}
return
#Right::
send {End}
return
#Up::
send {PgUp}
return
#Down::
send {PgDn}
return

I don’t have any idea about the high pitch noise.

Hi,

I didn’t updated this post as I promised, sorry.

After 1.5 years of usage my experience is generally positive.

Flickering and noise is still there. The wifi does not work with my older TP-Link router, but works with a cheap new Tenda router just fine. The signal is strong enough for me. I haven’t updated the BIOS. The TDP is high, the battery readout is about 11.8W at max. I bought a cheap Kingspec or KingDian SSD, it works fine and it’s faster than the EMMC. The OS is still on the EMMC though.

There are two major problems I discovered since:

1. The touchpad randomly stops working. This happens rarely, but when it does, it keeps on for days. It fixes itself after some time, but I managed to speed up the process by disconnecting and reconnecting the battery connector (inside the laptop). This is a very annoying problem, especially when I don’t have a mouse to use instead.
2. The SD card reader is unstable. It works fine for storing backups and large files. But when a program regularly writes to it, it crashes randomly. So I cannot run any apps directly from SD card, and cannot set it as an output directory for example a torrent client which regularly writes the card.

I have a minor problem, too. The rubber feet of the laptop are falling off. I have already lost the two front ones. This is an easy fix though.

And to say some positive thoughts:

The battery life is just amazing. The laptop easily withstand 4 hours of heavy use, and it goes up to 10 hours if you are careful. 10 hours is possible with a script like this:

This will turn off the screen with a shortcut.

Thank you for your answers. I need this laptop to work flawlessly, because I bought it to be my primary laptop. So I’ll definitely try the SSD install, for the additional speed. I’m planning to keep the factory Windows on the EMMC, and install Linux on the SSD. With the v5 it seems almost impossible. As I understand this laptop has UEFI, EMMC and limited bios, and these combinations makes it really hard to do what I planned. But I’ll try.

I haven’t noticed any flickering in the past 1-2 days. Maybe I don’t see it anymore (I doubt it), or is it gone for now. I use the lowest brightness all day, I’m used to it. I use my desktop PC and my old Laptop like this, too. So if there’s flickering, it’s a huge problem for me.

I didn’t realized that the TDP was modified, but yes, I’ve seen 8.xW consumption in BatteryBar. At idling it’s 3.8W. It would be nice to go even higher, I bought some copper sheets and thermal conducting silicone, so overheating wouldn’t be a problem.

Finally John Smith said above, that his charging status led goes to green when finished. Mine just goes off when finised. But I think the charging circuit works fine, when the laptop is fully charged, it seems, that it uses the charger only to power the laptop, and leaves the battery alone. So it shouldn’t be a problem to leave the laptop on charger and use it like that.

mAh doesn’t really tell you anything useful without the voltage. The real capacity can be measured in Wh, which is nominal voltage times capacity in Ah. So the real capacity of the Jumper EZBook 3 Pro is 7.6V*4.8Ah=36.5Wh.
