HP OMEN 15 charger overheating

tl;dr:

Solution #1, direct a fan towards your 200W HP PSU

Solution #2, buy a higher Wattage HP PSU and a 7.4 x 5 mm to 4.5 x 3 mm adapter

Hi,

During an extensive gaming session of a few hours I suddenly noticed a substantial drop in performance on my new OMEN 15 laptop. The frames suddenly became unplayable and when checking the taskbar I noticed that the laptop had stopped charging while being plugged in. After making sure the laptop was correctly plugged in, I nearly burnt my hand when touching the power brick: it was flaming hot.

Turns out, the laptop stopped charging because of the power brick overheating, causing the drop in frames.

I believe this event has left my charger damaged as it now routinely becomes quite hot when merely charging the laptop (without even playing games).

Is it possible to get a replacement charger using my warranty?

When comparing the 200W charger supplied with this laptop to the 2OOW charger of my old laptop, I noticed that the new one is substantially smaller, maybe too small to deliver that kind of power without overheating? Therefore, is it possible to use a different charger with this laptop, like the 330W one?

**UPDATE**

Ok, so I did some testing:

First things first, here is the comparison of HP's 200W PSU vs an aftermarket one. These two bricks are rated for the same Wattage while the HP one is about half the other's volume. Seeing this makes the overheating issue less of a surprise.

In the OP I inquired about a 330W OMEN PSU that HP has now stopped selling online. Despite HP's only feedback being "We haven't tested this PSU with this laptop", I can say that the 330W PSU works ... sorta. It charges the laptop fine, however, when gaming the laptop throttles itself back and forth between lowest and highest CPU clock speeds. This because the laptop recognizes the charger as non-standard through its dedicated ID channel. The mechanism behind this throttling uses artificial overheating signals, which can be circumvented on either a software or hardware level:

Software: Disabling overheating signals (Intel CPUs only)

Hardware: Spoofing the ID signal or transplantation of ID chip brick to brick, brick to adapter or brick to laptop

As my laptop contains an AMD CPU and I did not want to mess with hardware modifications, I have instead bought a 230W HP PSU. I can confirm that this one does not have any throttling problems. The 230W PSU looks exactly the same as the 200W one, but is slightly bigger and rated at 11.8A instead of 10.3A.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Did you try another charger?

While you respond to that, let's try these steps: 

• 1. Go to Start, search for Device Manager, and open this result.
• 2. Expand batteries.
• 3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.
• 4. Shut down the computer. 
• 5. Disconnect the charger.
• 6. Remove the battery. (only for removable battery)
• 7. Hold down the power button for 1 minute.
• 8. Insert the battery only. (only for removable battery)
• 9. Attempt to turn the battery on.
• If possible, try an alternate charger.

Hope this helps! Keep me posted for further assistance.

Hey I'm not sure if you're still checking this thread. I have the same problem with HP omen 15 rtx 3070 that comes with i7 10870h.

I'm actually thinking of buying another 200w power brick and connect them in parallel. Practically we could get a 400w psu. I know it kinda of over kill but since I'll be using this mostly for gaming and it's stationary, I think two power bricks wouldn't be an issue for me. What are your thoughts about this? Or maybe I'll just get a 330w psu and disable the thermal throttling.

There is one issue though. When connecting two switching psu, one will definitely draw more power than the other. But assuming at least some of the power draw will be distributed to both psu then this should solve the over heating and battery drain issue.

Also both psu will need to be opened up to get the cables fixed nicely and maybe 3d print a rack for it to stack them on top of each other. Let me know what you think.
