Hi.
After changing thermal paste on my systems CPU. I screwed it all together and now my sleep sensor is not working if i close lid, display stay on and doesn't turn off.
I must push the power button for 2 sec to sleep .. and if i close lid when charging the green battery test are very weak.
Photo battery light when is closed lid and opened.
Thanks for reply

At this point I suspect you'll need to take your logic board out again and strip the paste from the CPU again,
Once the paste is removed fully you'll need to bathe the board in reagent quality Isopropyl alcohol (85% or better) and lightly scrub it down to remove the residual traces of paste that made its way to the logic board from the first time.
I do strongly recommend using a good quality paste & cleaner like: Arctic Silver IFIXIT sells it as well:
Here's a good writeup as well: Technique: How to Apply Thermal Paste.
As to the overheating problem which started you down this path. Your system shouldn't have needed the paste replaced (just not old enough).
Often I see fan issues or the system was very dusty. I do recommend using a good thermal monitoring app like this one: TG Pro. So for for less than $20 US it's the best app out there. It should have given you a clue if you had a dust. fan, or heat sink issue.
Since we don't have any hard data to work from, you might want to replace the heatsink while your at it here. Just to be sure as I'm sure you don't want to do this still a third time ;-} If you remember did you see any wetness on the pipes or the logic board? If you did that was the liquid inside that leaked out. In any case make a good inspection of the heat pipes for any staining or pitted areas were there might have been a hole.

I tried and still not working .. i ordered new cable for sleep sensor and battery indicator and now i'm waiting for this .. but thanks :)
I installed new cable but not working ... i don't know what is bad :( i replaced cable and thermal paste ..

Sadly something on the logic board is amiss. I don't think you can go any farther here ;-{ I think its time to swap-out the logic board or see if Apple can fix it. I'm sure they will just replace the logic board.

You must have either unhooked something internally or it's not properly seated in place like it should be. Maybe a local computer repair shop will do it properly for little to no cost...

I tried unplug and plug all connectors and i tried reset SMC and NVRAM but not working .

Why did you apply new thermal paste on your CPU? Who's product did you use? And, did you fully remove the old paste?
As for the battery tester there is current leakage which is why the tester is lighting up slightly. Often thats a sign of liquid damage.

Because i had problem with overheating . but why is lighting up slightly only if is lid closed ? .. and if i turn off macbook, the battery led is working fine in closed and opened lid .

Current leakage here is likely some staining on the main logic board from the cleaner you used to remove the old thermal paste. This can also explain your sleep issue as well.
