This is a Google Pixelbook (i5, 8 GB RAM, 128GB) bought in 2018 and out of warranty. Last Sunday, after a software update, pixelbook rebooted andafter a while the screen turned black and since then I haven’t been able to boot it up. When I plug the charger, led is solid green. But if I try a boot, a hard reset, or anythin else, nothing happens (except at the led level there is some activity) I have a case opened at google support but because this is out of warranty, agent was pessimistic that they can do anything. Here it what I have already tested: standard boot but pushing power button: nothinghardware reset - Holding refresh and pressing powerrecovery mode - Holding Refresh and Escape and pressing poweranother one - Connect the charger to the Chrome OS device. Hold the side power button + Refresh key and remove the power adapter as they keep holding on those buttons. Wait for 1 minute. Press the side power button to test the device. Connect the power adapter and monitor the LED color. Device should try to turn on and LED should blink or have solid color. Nothing has helped so I guess there is an hardware issue. Do you think it could be the motherboard to be replaced ? I am tempted to try to follow - Google Pixelbook Motherboard Replacement
Hi There, Another thing you can try yourself is to check if the problem is not just a loose component, you’ll need to open up some/all of the panels though. First thing to try is to remove and re-seat the “easy to get to” components like the RAM and SSD/HDD etc. Also take out the main battery whilst testing, it should be able to start up with the AC adapter alone. A bit more advanced but do-able check is to take the CPU off and re-seat it. but for this you’ll need to get some new thermal compound and you’ll need to remove the old compound with some q-tips and rubbing alcohol from the heatsink and CPU before assembling back together. If it still doesn’t work then the next step is a complete disassembly and testing all components unfortunately, for this it’ll be best to take it in to a repair shop that has the proper spares / testing equipment on hand.
