OnePlus 5 dead, won't turn on, no charging LED

Hello everyone,

Recently my OnePlus 5 was on low battery at night, so I plugged it into the charger. When I woke up in the morning, the phone was dead and I could not turn it on anymore. This has been the state since then, I have not been able to turn it on and the phone also does not show a LED when plugged in to the charger etc.

I have already tried a few things mentioned on the forum, such as different combinations of the volume and power buttons, but nothing worked so far.

Mainly I am trying to figure out now how determine whether either the charging port is dead, or the battery, or the motherboard:

- If simply the battery was dead (and nothing else), would the phone then show an LED when plugging it into the charger, or not?

- If the charging port was dead (and nothing else), such that it did not charge and just shut down on its own, would I be able to power it on at least for a second or so before it dies again?

Just trying to figure out if the motherboard is actually dead, or if there is still some hope for me. Thank you very much!

Let me know if you have any ideas - thank you!

Hi @stevieh ,

Connecting a charger should give an indication on the phone if the USB connector and its connection to the systemboard was OK, as long as there is no other problem with the systemboard that is.

The battery may be depleted so far that it may not be able to provide enough power to do anything without it being recharged first (or replaced - may be depleted beyond recovery).

Use a strong light and a magnifying glass to visually inspect the USB port for any bent or broken (missing?) pins (check pins 1, 4, 9 & 12 top and bottom rows) or any obstruction e.g. lint, in the port enclosure that may be preventing a good electrical connection. If there is any debris do not use a metal pin or probe to try and get it out as you may damage the pins or cause electrical problems in the phone. Use a vacuum cleaner instead to try and suck it out. If still no good then use a sharpened wooden toothpick to gently prise it out.

If the port seems to be OK, check if the port seems securely connected to the board. To do this, plug in the phone charger cable to the phone. Do not plug the other end of the cable into anything! Then grab the phone firmly in one hand and grasping the inserted cable plug with the other hand, try to gently move it up and down and side to side and check if any movement in the USB port is detected.

If so (or even if not) the phone will need to be opened and inspected and further tested to ascertain what the problem may be.

Here’s the ifixit OnePlus 5 repair guide. This will help you to open the phone so that the USB port can be inspected to check if it is secure and then tested to make sure that it can pass power through to the systemboard. You will need a DMM (digital multimeter) and know how to use it, to do this kind of testing. Note the warnings in the guide when opening the phone.

If the USB port and its connection is OK then there is a problem with the systemboard. Without the schematics for the phone (I can’t find any) it will be difficult to find out what and where the problem is.

If opening the phone yourself seems too daunting, contact a reputable, professional mobile phone repair service and ask for a quote to fix the phone

Hi @jayeff ,

This is a great reply, thank you so much. One thing I found out is that if I connect the phone to my computer through a USB cable, and then press volume up on the phone for a few seconds, it will be "detected" as QUSB_BULK by the computer. If I then press power for a few seconds, the QUSB_BULK will go away. So it seems that this switching of modes works and that this signal is at least passed to the computer.

Could you let me know if such behavior is indicative of one of the components working? That is, would such behavior be possible if the battery was completely dead? Is it indicative of the motherboard working? Or indicative of the charging port working?

I am just trying to figure out which components are involved in this process, because this behavior is basically the only thing that still "works" on my phone. Note that during the whole process, the phone itself does not show any LED, display, or anything.

Thanks a lot!


Have you ever found a solution Steffen?

I have the exact same problem at the moment.


@kenziner No I have never really found a solution. I am still considering buying replacement parts and figure out if it can be fixed. In the meantime I got a new phone obviously. Any progress on your side?
