GET IT RIGHT EKEN!

is there any app or way to put them off ?

Nope, I'm guessing they're controlled by something on the SoC. It might be possible to modify this in the firmware, but definitely not with an app.

soldering iron = solution

If they are controlled by PWM then changing the duty cycle can reduce their brightness but thats a lot of stuffing around. Iam going to replace with lower power LED's or increase the value of the current limiting resistor (If eken even bothered to put one in that is!!!)

I would be shocked if they were on a PWM what suggests to you that they are? Considering the lack of care with which they selected the leds themselves I too would doubt they even have limiting resistors.. I was actually suggesting just desoldering them what function do they provide?

Indicate that is on? That duuh, that one can go. Wireless active? Iam sure feedback on that is provided through the OS. Charging?Chinese manufacturers seem to LOVE their LED's. I once had a DVD player that had OFF written in superbright LED's... when it was off.

I would assume that you are correct though. I very much doubt that there is an alert LED like you get in a nexus one or a droid so essentially they are useless. Oh also yes there is a wifi icon displayed on the status bar so the wifi one is definitely superfluous as is charging.When I built my first computer I lined the case with these RGB leds that had an IC that cycled them through all the colours once every 45seconds.... that was a mistake it was hypnotic and stomach turning especially when they all got out of sync.

Actually as an mental exercise we can work out what increase in life disabling the LED's will give.1) Operating time is 2 hours2) We find out battery capacity in mAh (written on battery)3) Using that we can work out device draw4) Assume superbright LED draw is around 40 - 50 mA each - total of 20mA5) Work out what percentage LED is of total draw & calculate increase in lifeAnybody know the battery draw in mAh??

battery is 7.4V 2000mAh so 14.8WhLEDs together draw say 120mA for two hours at 2.5volts = 0.6WhSo 1/25th of the battery drain very roughly.

I wish there was a way to change the colour like on my g1.I like the blue lights on this tablet. thyre not overly bright like the red ones.

How easy would it be to drop a resistor onto the tracks just before the leds?

So the screen is backlit by LEDs? That might seem to indicate an easy brightness fix...(can't wait for mine to get here...)Dan

Hello, maybe a very cheap solution can be what i do with other gadgeds with led?s, just use a blue permanent marker (the one you use to write on the cd?s and dvd?s) and with care paint over the leds, the marker is not totally opaque so the light will take the blue color instead of red one (at least for the visible part of the leds, with the part under the case they are still red, of course)...when my m001 arrive if i don?t like the red color maybe i?ll try with blue or green marker... if you don?t like it simple clean it with alcohol...cheers...

LEDs are monochromatic light sources, i.e. they produce light on a specific wavelength, in this case red. A blue filter on a broad wavelength red light source would work by simply filtering part of the red out and letting the blue parts thru - problem with LEDs is that there is no blue part to let thru, so this should just make the red LEDs dimmer.

why not simply replace the leds with less brighter ones (they consume less power too!)
