Re: Thinklight for X61 tablet

Yes, I've used EaglePCB -> transparent foil negative laser printing -> UV light positive on PCB ->FeCl3 etching, but for such a simple circuit can be used direct pin to pin soldering (if you have a steady hands and good vision).

Re: Thinklight for X61 tablet

You can use any kind of conductive material with surface area bigger than 25mm2 or 5 by 5 mm. I've used 6X6 mm copper foil stripped from PCB. Main principle is , bigger sensor - greater sensitivity (and depending on Rs /Cs as I mentioned above). For more accurate info read the application datasheet ...

Re: Thinklight for X61 tablet

Hi Marcel, If you mean the electronic circuit diagram of x61t ,I don't have it. I've used that all the devices on the display have a power supply (lcd , fingerprint reader, inverter and so on). Main principle is by using a multimeter to find GND pin and a supply pin with needed voltage. In my case I...

Yes, but if Intel didn't lie in specs we'll gain near 8 times less mass and 10 times less power consumption compared to a most regular SSDs .

Need advise about WD HDD speed

Can you please tell me are the tests above normal for WD scorpio black 500 on x61 tablet. I've watched numerous reviews about this HDD and they all are with about 15-25% better results than mine. Can it be because of SATA 150 ? Can someone with x61 tablet and WD scorpio black 500 post his tests for ...

Re: Need to replace my lcd

It is not so hard to transfer the digitizer on new screen - only 2 screws and a sticky tape to deal with. It will be cheaper for you to buy an lcd without digitizer. There is very nice video clip for that http://vimeo.com/3933798 - look it and think again

Re: looking for pics... X6 tablet without displaybezel

To Uwe : look at this clip it might help you for disassemble : http://vimeo.com/3933798 the most important is to know that the bezel is glued to the LCD with a double sided sticky strip so be gentle due to disassemble. The other problem are side clips - be careful with them, don't rush, take your ti...

Thank you very much for good words! Yes , the LED driver is controlled from the same PWM signal circuit as a CCFL inverter so it support brightness dimming with the Fn+Home and Fn+End keys.

Re: Need Advice (buying x61 tablet)

Yes, this LCD with FRU 93P5607 will work for you, but I am not sure for digitizer ,because it's not mentioned is it G4 or G5.
In my case I bought display from itthinker (from ebay) with FRU 93P5609. As I told you LCD's from both FRU are the same, difference is in digitizers.

Hi davepol, I have x61 tablet (7767) and I've done this a month before. There are 2 types of sxga+ screens that you can use - HV121P01-100 and HV121P01-101. Difference between 100 and 101 is in digitizer (if you buy it with it, if you not than this number doesn't matter) - one is G4 other G5. No nee...
