hi i use pavilion 14-al107nt and only changes i made is changing thermal paste with artic mk4 and battery(probably bad quality) and added kingston 16gb ram into it so total 24gb but my problem occured after changing cpu voltage setting by throttle stop i dont remember which core cache ones changed but i undervolted them too much because -80mv didnt gave any problems but after making it -125mv, thats where screen goes to black but i can move mouse cursor and see it then i closed and tried to open again and it shuts off around 5 sec, doesnt let power again and ac power light(next to the power socket) goes off but after pull out and in it goes orange and can power again and it goes white then 5 secs later it does it again,i tried with/out cmos battery and 2 rams(finding if those are faulty but no), i tried powering without battery but it doesnt responds just power light goes blank then white again, dont know but leaving it charged from midnight kinda let me open it, it did w10 update then i logged in and deleted throttle stop.ini(which is keeping settings same so deleting would be stock settings) but it didnt worked. tried cmos reset and windows logo + b (forgot what this does) it didnt worked tho. i had fan error if its the temperature i have 4blower fans directly hitting air intake side(with or without doesnt change)

Hi @Hoorow,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
It sounds like your Pavilion 14-al107nt is experiencing a range of issues after making several changes, including undervolting the CPU, replacing the battery, and adding RAM. Here’s a structured approach to diagnose and potentially resolve the problem:
1. Reset BIOS/UEFI Settings
- Disconnect Power: Ensure the laptop is turned off and unplugged.
- Remove Battery: If it's removable, take out the battery.
- Clear CMOS: Look for a CMOS battery on the motherboard and remove it for a few minutes to clear the BIOS settings. If your laptop doesn't have an easily removable CMOS battery, you might need to look for a jumper to clear the CMOS (refer to the motherboard manual for this).
- Reinstall Battery: Reinsert the CMOS battery if you removed it.
- Reconnect Power: Plug in the laptop and try to power it on. This will reset the BIOS to its default settings.
2. Check RAM Configuration
- Reseat RAM: Power down the laptop, remove the RAM modules, and reinsert them firmly. Ensure they are properly seated in their slots.
- Test RAM Modules: Try booting with just one RAM module installed to rule out issues with one of the RAM sticks.
3. Inspect the Thermal Paste and Cooling System
- Verify Thermal Paste Application: Ensure that the thermal paste was applied correctly and evenly. An improper application can lead to overheating.
- Check Fans: Ensure all fans are functioning correctly and are not obstructed. Verify that they are connected properly and spinning when the laptop is powered on.
4. Revert Voltage Settings
- Undervolt Reversal: If possible, revert the undervolt settings to their default values. Since you have deleted the ThrottleStop.ini file, it should return to default settings, but double-check to ensure that no residual settings are affecting the laptop.
5. Perform a Hard Reset
- Power Down: Disconnect all external devices, unplug the power adapter, and remove the battery (if removable).
- Press Power Button: Hold down the power button for 30 seconds to discharge any residual power.
- Reconnect Power: Reconnect the power adapter and battery, and try to turn on the laptop.
6. Check AC Adapter and Battery
- Verify Battery and Adapter: Ensure the replacement battery and AC adapter are functioning correctly. A faulty or incompatible battery could cause power issues.
- Test with Different Adapter: If possible, try using a different AC adapter to rule out issues with the adapter.
7. Inspect for Hardware Faults
- Look for Physical Damage: Check for any signs of physical damage to the motherboard or other internal components.
- Listen for Beep Codes: If the laptop emits beep codes during startup, consult the laptop’s manual to identify what they signify.
8. Reinstall Windows
- Reinstallation: If you can get the laptop to boot, consider performing a clean installation of Windows. This can help resolve any software-related issues that might be causing instability.
I hope this helps.
Take care and have a good day.
