X230 FHD nb51 mod, software brightness control
X230 FHD nb51 mod, software brightness control
Hi, I recently completed my X330 mod, using parts from XYTech (nb51 adapter and Sharp screen). The brightness is controlled using power button.
I keep running into mentions of Windows software capable of controlling brightness, does such thing exist?

Re: X230 FHD nb51 mod, software brightness control
Uh-huh. This is supposed to work with modded screen? And for some reason all of those work, but Linux still has not figured how to control the brightness?

Re: X230 FHD nb51 mod, software brightness control
You asked for Windows programs.
AFAIK Linux brightness control should work OOTB, at least with nitrocaster's mod, but I don't know what nb51 has cobbled up.

Re: X230 FHD nb51 mod, software brightness control
Yes, I asked for Windows.
I assumed (wrongly, perhaps) that since Fn combinations don't work, there's some magic involved and brightness can only be controlled with power button. I read a lot of threads where there's mention of some special software, such as: viewtopic.php?t=125243#p811491, but no link to actual software

Re: X230 FHD nb51 mod, software brightness control
why'd you go for the 51nb instead of the nitrocaster mod?

Re: X230 FHD nb51 mod, software brightness control
Mostly to get everything from a single source: top half assembly and the mod board. Was also somewhat cheaper than 2 separate postings.
Re: X230 FHD nb51 mod, software brightness control
You should go with coreboot FHD mode varient.
Re: X230 FHD nb51 mod, software brightness control
I suppose you could also ask XYTech (possibly via reddit messaging), he's quite happy to chat and is in contact with 51nb members. If you do find a solution, please post here

This seems like a Linux utility, isn't this right?stasheck wrote: ↑Fri Dec 04, 2020 7:06 amHere's the utility: https://github.com/timothy-ha/X330-Backlight
So is it working via the USB interface? Does nb51 kit have USB interface?var devices = HID.devices();
device = new HID.HID(4292,33742);

Re: X230 FHD nb51 mod, software brightness control
you need to download lenovo Thinkpad Hotkey application, install it.
then you need to download the custom made app to adjust screen brightness for X330. Do a google search for this lightweight app.
it works fine and great.

Re: X230 FHD nb51 mod, software brightness control
I use this simple python script
Code: Select all
#script that changes brightness on 51NB thinkpad X230 X330 FHD 13.3" LCD modification
#detects changes in Windows system brightness and sends a command to the LCD driver
#change vendor_id and product_ID to fit your hardware device under Device Manager->Human Interface Devices
import pywinusb.hid as hid
import wmi
def sample_handler(data):
print("Raw data: {0}".format(data))
#sends HID command between 0-255 to USB LCD controller
def updateBrightness(brightnesslevel):
filter = hid.HidDeviceFilter(vendor_id = 0x10C4, product_id = 0x83CE)
hid_device = filter.get_devices()
device = hid_device[0]
device.open()
device.set_raw_data_handler(sample_handler)
out_report = device.find_feature_reports()[0]
cmd = (0,
brightnesslevel,
)
buffer = [0x00] * 2
i = 0
for x in cmd:
buffer[i] = x
i += 1
out_report.set_raw_data(buffer)
out_report.send()
device.close()
#detects changes in brightness
def brightnessChangeDetect():
c = wmi.WMI(namespace='wmi')
watcher = c.WmiMonitorBrightnessEvent.watch_for(
notification_type="Modification",
delay_secs=1
)
event_happened = watcher()
brightnesslevel = int((event_happened.Brightness)*2.5)
updateBrightness(brightnesslevel)
#main program
while True:
brightnessChangeDetect()

You can try pm boutch55555 on reddit, he mentioned that he has some kind of driver for it "There is a windows driver for that board on 51nb, PM me if you want a Google drive link.", thread link https://www.reddit.com/r/thinkpad/comme ... d_for_the/
Not that long ago I converted my x230 to FHD too, totally different machine. Went a little further and changed speakers to iPhone XR speakers and it sounds as good as it looks
EDIT: Ooops, didn't see the date when thread was created :X
