Context

I bought a game laptop a few years ago. I wanted to use this laptop in addition to my studies, but in my spare time I wanted to play games. This also worked for a while and I was very happy with it. It's been a long time since I've used this laptop but I took it out of the closet again this week and plan to start playing simple games on it.

But I suddenly remember not being able to play on it at all. What I can still remember is that my charger broke down at the time and I bought a new charger from the MediaMarkt. The staff recommended a charger to me at the time that would work on my laptop. This one indeed became, but later my laptop started to react a bit strangely. I don't know if this is linked to the charger but I'll explain.

As soon as I have the laptop working, connected to the charger and then try to play a game, it is often hit or miss. The frame rate of the games is then so low that my integrated video card is even faster. To solve this, I have to force shut down the laptop by holding down the power button until I hear that the hard drive is down. As soon as I restart the laptop and then play a game, the problem seems to be solved. The games then have the frame rate associated with the GPU 1.

As soon as I disconnect the charger from the laptop, the frame rate shoots down. If I open task manager and look at the CPU, I see that I am clocked at 0.78 GHz, the GPU is 100%. If I reconnect the charger to the laptop, the problem is not solved. I see that my CPU is back to normal clock speed but performance in games has remained unchanged. Once I want to game again, I have to force the laptop out completely until I hear that the hard drive is down and then I can game again.

Laptop Adjustments

• Bought not original charger (which I replaced today with an original one)
• WiFi module upgraded
• Reapply thermal paste (3/4 years ago)

What I've tried yet?

• Contacted HP when my warranty was still running but I was in the middle of my exams and the warranty would expire during my exams, I then asked for a postponement and the employee who gave me at the time agreed to me but when I called after my exams were over there was nothing recorded and once I was unlucky
• Motherboard in the over baked
• ThrottleStop used
• Disabling energy savings in Windows and NVIDA GeForce Experience
• Updating the BIOS
• Tried different Windows version
• Tried different GPU drivers
• Search on Google

After a lot of testing I think it might be at the charging port. I am very curious what the problem can be and what causes it and whether it can be solved.

• "Motherboard in the over baked"

Please elaborate...I hope you are not saying you baked the motherboard in the oven?

Otherwise, I tend to agree it is a power issue. Maybe a bad, underpowered adapter. Please be really specific about the type of adapter you are using. Or, as you suggest, a damaged power jack.

A friend of mine worked at ASUS and offered to rebake the motherboard so that the transistors should better connect to the motherboard. This is not done in a home oven. I haven't seen the process myself and don't know if it did since I don't see the difference.

I ordered a charger last Saturday, which I received yesterday. This is an original HP 90W Smart AC Adapter EURO.

I'm almost sure it's a power issue. I also read a lot about this on Google if I was allowed to look it up using my processor. Is there an official way to order the power jack?

I have seen a few motherboards baked and it usually does not do much and is a last resort when the laptop no longer POSTs. It is a guerilla repair that serious technicians do not usually attempt. But what is done is done. This is your Service Manual:

The power jack is a separate replaceable part you should be able to find on sale for not much money. Definitely worth a try to replace it. 

(13) Power connector cable 806746-001

HP will no longer stock this part but will be available from eBay or other 3rd party sites:

See p. 57 for discussion of disconnecting the power connector cable from the motherboard.

Post back with any more questions and accept as solution if this is the info you needed.

Thanks I'm going to order the part.

I'll see if this helps and then share the result
