Uhhh... Quite a story with these Chuwi laptops.
Bought 2 Chuwi Lapbook SE laptops. Great laptop... Until it stops working all of a sudden.
First one worked a week until it just shut off and never came back alive again. Locals said it was the CPU, but could not explain how they tested. One of these did not even disassemble the laptop. Just connected a charger (their own charger) and came back telling that it was the CPU. He might have also connected something to the HDMI port, but I saw only from far away, so not sure. After all of the local workshops had to send the motherboard to the Chuwi factory for repair. Already a full month there and no results. Even no replies... Ridiculous service.
Anyways the issue now is that the second laptop has now done the same trick. This time worked about 4 months. Wow...
Completely dead. Only power connector LED lights up and I can hear ticking sound from somewhere off the motherboard. Ticking sound only when power supply is connected.
Then suddenly turned on after disconnecting the battery multiple times and trying to boot different ways. Turned on and worked for 5 more days perfectly (though only with charger connected, battery percentage always showing 0%). All of this time distinctive coil whine while working.
After the 5 days, in the morning just not turning anymore and this time I think for good. Nothing helps.
Decided to check the batteries from both of the laptops. 2 batteries tied together to create a higher voltage battery pack.
Designated voltage: 7.6V
Max power: 8.7V
Teared off the tape a bit to get to the battery pack control board and the contact points. EXPECTED to measure 3.8V off each battery cell (Thus 3.8+3.8=7.6V), but multimeter only showing 2.8V off each cell.
Measuring off the contact points from the battery pack to the motherboard, not really getting any values... From any of the black wires to any of the red wires - 0V.
Only value I can get is when the charger is connected, I am getting 3V from the yellow wire to the red.
Also one chip (power regulator I think?) gets hot very quickly as soon as the charger is connected.
Any ideas where to look? Battery packs dead?
Power regulator gone bad? Hard to distinguish, but might be the source of the ticking sound
Really the intel CPU as they said? I always like to monitor temperatures in my laptop and CPU never gone over 75°C. Normal usage ~60°C. Would be weird to have 2 INTEL cpus dead so quickly
