Chosen Solution
So i disassembled my lenovo ideapad 330s because i wanted to clean the vent… i could see it was pretty dusty. Thought it went well, but after reassembling it, it wont turn on.. No lights when pushing the on button or anything. No reaction when putting the charging cable in either. Really hope someone can help me to figure out what i did wrong.. I basically took everything apart to clean everything, because i thought i might as well while im at it… turns out that was a mistake, should have kept it simple.. Didnt use water to clean by the way, just a brush and a tooth pick. Maybe someone can see something wrong in this photo. Thankful for any help
Hi Hanna, Have you downloaded the pdf service manual? You might find it useful. Shows all screws, etc. https://usermanual.wiki/Lenovo/330s14ikb… The connector with no ribbon cable connected just the the left of your yellow circle is connected in the service manual. I would investigate this. It seems to come from under the battery. The black and red wires you mention are for the RTC or cmos battery, which stores the BIOS or UEFI settings and the time, but this would not stop it powering on. It is vitally important that all cables are correctly inserted. All the parts of the machine are interconnected and dependant on each other. The problem may be that some thing you did incorrectly the first time you have repeated each time. Read and study the service manual and review what you have done….oh and always shut down and disconnect the battery. I still suspect your problem is just a cable especially as you get no power lights what so ever. Let us know how it goes. Everything has a cause. Every problem has a solution and usually a simple one. The hard part is finding that simple solution.
I don’t think the keyboard cable is seated fully into the keyboard connector on the board. Generally the individual lines which are visible at the end of the keyboard cable should not be visible and be inside the connector. Try pushing it in a bit while the connector is in the unlocked position.
Hey. In the picture I can’t see anything obvious,other than that ribbon cable connector that has nothing plugged into it on the bottom left of the motherboard. I don’t know if there was anything there or not.. But did you disconnect the battery prior to disassembling? If not,it’s so easy to short circuit something. You can connect a high voltage line to a low voltage line,and it will damage something not meant for high voltage,and maybe short a capacitor. have you made sure you reconnected every ribbon cable,and that they are all attached very well? Did you unplug the battery and hold the power button to drain some left over power then plug it back in? Is there any sign of heat in the laptop? Did you drop anything at all or shove in a flex cable too hard? edit: I can see what Ben means. It looks like it’s not pressed in all the way.
