Ok that would make it a vibration or roller ball tilt switch. It must tell the MCU the tool is up or running.
Hold it up to your ear and shake it, see if you can hear the ball/roller/spring inside. Or put a DMM on continuity and tilt/shake the sensor see if you get a closed switch reading.Leave a comment:

The part has no leads, it looks like it fits in a socket? Designed to be replaced.
I would guess a gas discharge tube or higher power RF TX capacitor.Leave a comment:

Hi All,
Could anybody please recognize this component? It has no markings and there is no designator on the board. It has no continuity, diode test shows also OL both ways.Attached Files -

Hello everyone
I have been working on this laptop mentioned in the title, it initially had a blown PQ4410 mosfet. After I replaced it and repaired the damaged PCB the thing started working again, but there is still another problem. The laptop won't recognize genuine battery and charger. I have 3.3v KBC PIN36 PS_ID and this is pretty much where my knowledge ends.
Where should I go next? Replace the KBC or measure something else?... -
Hi, the pc does not recognize my SSD, I was testing Volt and the SMC_OOB1_D2R_L, and gives 0.03v approx, and it should provide 3.3v I think, what can be the problem? maybe is the resistance (R86101) I cant test it with my multimeter too small, but I don't think that would do the V go to 0.3v, and SMC_OOB1_D2R_L has continuity with the test point. I think all other pins are okay.

Hello! : Laptop model: Acer E1-510 Z5WE3. Regardless of the OS (W10/11/8), it doesn't recognize the wifi mouse until several resets. Tried all possible drivers.
I brought new Bios- Z5WE3214W v. 2.14A. In vain! Does anyone have a solution? Thank you!
