T61 Broken Inverter Card OR LCD cable assembly, which one?

#1 Post by jwcacces » Fri Mar 16, 2012 8:07 am

Hello All,

I have a Thinkpad T61 6465CTO with two problems.

1) Some of the indicator lights inside, beneath the display do not work:
  • Wifi: working
  • Bluetooth: NOT working
  • WWAN: NOT working
  • Numlock: NOT working
  • Capslock: working
  • HDD: NOT working
  • Power: NOT working
  • Battery: NOT working
  • AC Power: NOT working
  • Standby: NOT working
None of the indicators that show outside when the lid is closed work either

2) When the computer is in standby / sleep from lid close, it will wake up when the unit is moved or shaken (even when gently disturbed). I know the lid sensor is magnetic, so I've tried sticking a strong magnet to it. In that case, it will sleep and will not wake until the magnet is removed, even when shaken violently. (it will not inappropriately turn while in hibernate or power off, ie. when opening the lid would not be expected to turn it on)

My question: How can I tell if the problem lies with the inverter card, the LCD cable assembly, or both?
Follow up question: If I do get a new inverter card, should I favor the Foxconn version of the TW Sumida version?

Thanks,
James

I would look at the cable where I could see it and see if it looked cracked or split. If not, I would try the inverter - easier and cheaper. I never found that one brand of inverter was better. I get whatever is cheaper

Yeah, the same thing happened with my X61, but it was because I accidentally tore the LCD cable when I was disassembling it. The panel itself displays fine, but all of the indicator lights were out except for wifi and bluetooth...

I have both the cable and inverter, I'd consider replacing both if you want the easiest solution.

I'd be open to offers/trades, send me a PM if you need either, or both.
