My HP Pavilion x360 13-S104NE has stopped turning on after replacing the battery thanks to AliExpress shipping me a battery with reversed polarity at the terminals which fried the motherboard

The motherboard is the main fried component, but the screen and keyboard/trackpad assembly are also broken, as well as many missing screws thanks to my idiot brother, totaling new parts for repair at more than $700, and considering this is a 9-year-old laptop, my dad says it is not worth repairing, but he wont buy a new laptop either

Any other ideas other than an entire new motherboard such a specific chip? The rest of the components could be taken care of by turning it into a desktop setup, and fixing it slowly as I save up, although considering I don't have an allowance and get my cash by finding coins on the street every few months, that is probably going to take years

EDIT 29/3/25: When connected to the charger some of the capacitors near the charge port become really hot capping at over 63°C

To preface things, I have an HP Pavilion Laptop, model HP Pavilion - 15-cw100.

I updated my BIOS to the latest version (F.48.Rev.A) through HP's official website. However, once the writing to the BIOS was complete, I got an error saying "Verification of flashed BIOS Image failed". With this, the system went into a boot loop where it would boot to the HP BIOS Recovery and repeat the flashing process only to return the same error message.

I then attempted to recover the BIOS using an external USB, and I attempted to flash F.48.Rev.A with the USB, and I got the same message. Upon analyzing the logfile, I got something that mentioned "Verify of Block 46 Failed". I then repeated the process with versions F.47.Rev A and F.46.Rev.A only to receive the exact same error.

When recovering the BIOS with F.42.Rev.A, however, it successfully recovered the BIOS and displayed "The system BIOS recovery is complete". I let the laptop sit and perform its reboot sequence, and the laptop turned off after a few minutes.

Now, when I turn on the laptop, I see a black screen and the laptop turns off after a few seconds, and this process repeats again in a loop.

Some things I have done to try to fix this:

1. I removed the NVMe drive, battery, and reseated the RAM. I'm running the laptop only off of AC Power as of right now.
2. I have tried both the Win + B and Win + V Keyboard combos with a USB containing a recovery BIOS as suggested by the HP Troubleshooting Guide, but the laptop simply turns on to a black screen and turns off after a few seconds and loops.
3. I pressed and held the power button for a few minutes with the laptop not being connected to power, to maybe power cycle it.
4. Followed whatever was suggested in the post Here, with the user having the same model of laptop as me.

As of right now, I'm open to doing anything to the laptop to try to fix it, as the laptop is almost a year out of warranty.

Thanks in advance.

recently when travelling with my laptop in my bag it must have experienced some sort of blunt trauma.

Along the top of my trackpad has sunken. Whilst the keyboard does not register clicks anymore. Although is still fully functional bar from that.

Is there anyway I can realign or fix this problem? Many thanks. I have attached a photo.

The power jack glows but when I press the power button, nothing happens.

Also, the 3 LED indicators, are all off when I plug in the adapter.

If the battery is connected, all 3 LEDs turn on and stay lit.

The laptop does not turn on in any way.

Anyone have a clue?

Thanks.

I have a HP Pavilion model 15-P243sa ( beats audio ) , CPU N3540 (2.16ghz) , 8GB ram, 1TB HD.

Out of warranty, but well looked after and more recently the screen in the top right hand corner has become slightly dark.

I have Googled the issue and found some similar topics and tricks to remedy the problem, which resulted in no solution.

I have updated the BIOS and done a factory reset and still no fix!

Unable to connect to external monitor.

Has anyone else experienced this problem?

If so what was the answer?

Replace the screen?

Unable to find any similar screen replacement procedures on ifixit.

Is this type of screen easily disassembled?

Many thanks for reading.
