Steam Deck wont turn on, After applying Honeywell Ptm pad and upgrading the ssd

[piffntaltul]

Hello yall,

First things First, as this is my first time posting in a forum and definitely first time trying to describe a problem considering electronics..English is not my native language so ill try to do my best describing the problem in detail and keeping it clearly written.


So it all started with me deciding to upgrade my ssd card from 512gb (original piece) with a new ssd 1TB from Sarbent.

I was about to open the deck and watched Gardiner Bryant changing his thermal paste with the Honeywell PTM 7950 Pad a few weeks ago.So i decided to do the same, as it didn't look to complicate and Ive done stuff like this before.

And so i did, I opened the Deck and replaced the paste first, with the Battery disconnected...

leaving the older ssd card inside, since i wanted to make sure everything is running alright and i planed to make an Image Clone of my current deck into the new ssd before replacing it.


I turned the Deck on, and everything seems to run just fine. so i began the next stage which would be making an Image Clone of my current OS with everything inside it through the Konsole (using this command:sudo dd if=/dev/nvme0n1 of=/dev/sda oflag=sync bs=128M status=progress) and plugged the new ssd to the deck using the Sarbent M.2 enclosure (usb C).

This is the point where stuff got a bit funny, as my screen back light suddenly dimmed to minimum and few seconds later turned off completely, while Konsole is running already with the image cloning.

i couldn't tell if the deck was on or off, i tried to push the power button but there was no response, so i disconnected the enclosure, and tried a Hard reset for the deck.

at this point the deck was unresponsive, and wouldn't boot normally, i would get beep sound confirming it was turning on but nothing would appear on the display, actually it seemed like the display wasn't turning on at all.


So i began troubleshooting the problem with some guides and posts from forum which kinda described my problem.

Eventually i managed to turn the Deck on with the charging cable on after leaving to charge for an hour or so...

And the i could see a new problem showing up, which is the deck not recognizing the Battery, icon was an empty battery logo with a plug inside of it, so i went to settings and there in Battery info it would show me two question marks instead of info about the battery.

So i troubleshoot again, and tried to find some similar problems in google, and decided to reinstall the OS using the Recovery image from steam.

to do that i had to use my Jsaux dock, so i could plug a USB flash drive and have power simultaneously.

the installation went smooth, and the Deck restarted, this time showing 99% on the battery but then shutting down completely after a few seconds.


This is the point where im stuck, the deck wont show any sign of recharge, wont boot at all, with the charging cable in or out(i checked the cable, it works with my phone),

with charging cable on but battery out...

i left my the overnight without touching it as i thought it might got overheated(?)

and tried again today but still no response..


so yea, it turned to be a very long post because i tried to keep all the details since at this point i am a bit clueless about what exactly happened, and would really love to find a solution.

Did you damage the battery cable at all? Take a look and see.
I know when I replaced my 64gb m.2 and installed a 1tb Mine would not turn on but I plugged in the power cable and left it there for under 5 minutes and hit the power button and it worked fine. Take the back off unplug the battery remove the m.2 and then replace it.
Make sure the screws are not too tight because that can also cause problems with some motherboards if the heatsink screws are too tight.
Something to Note its rare but could be a bad m.2 ssd you installed.

Hi! thanks for the reply, had forgotten that i added a post in steam forums besides Reddit.
eventually i had to RMA(had to pay 200€ for a new mother board) since its seems to be i had a damaged battery power controller...
kind of unfortunate i guess and probably not caution enough by my side..
anyhow i managed to apply the upgrades i wanted on the new motherboard!
