My Laptop Suddenly Died

I have a HP pavilion x360 14-ba163tx that I bought last year. I had no problems using it and I'm happy with my laptop.

Until last week.

On Wednesday, I turned on my laptop, charged it and used it to check a windows 10 update. After that, I put it on hibernate and put it back in my bag.

2 days later, I tried to turn it on but the boot logo won't show up. The LED power indicator turns on but then it turns back off. I plug in it's charger thinking it ran out of power. The charging LED also turns on. I tried turning it back on again but the screen still stays black. Then I noticed the fan and HDD running and the power indicator turns on for a little bit before they suddenly stop and start again by themselves over and over again until I manually turn my laptop off by holding the power button.

The next day, I brought it back to the store that I bought it from and they said it was the motherboard. I was very confused, because it worked fine on Wednesday and I didn't even turn it on until Friday night. They said the HDD, RAM and SSD still works.

I also don't really use my laptop that often nor do I use it for heavy programs. Only some like, Skyrim, Sims 3 & 4, Adobe Lightroom, Office and surfing the web. I also undervolted it so that it will run cooler while being stable because back then the laptop would get hot even when using it for surfing the internet.

My warranty ended last month and they said replacing it is basically buying a new laptop. I want to know what happened to my motherboard that suddenly died after one year. I had an acer laptop 3 years ago and it's still running smooth. I'm confused as to why my HP laptop died only after 1 year.

Any idea what happened and what I should do? I sent an email to HP but they haven't replied yet.

Thanks!

Yeah, I’m not surprised the motherboard may be bad - it’s a common HP Consumer failure. To make matters worse, you have an HP that needs a complete teardown to work on. The issue with their motherboards is they have a tendency to fail in 1-3 years, especially in laptops. It doesn’t happen in every single HP laptop, but it happens on a disproportional amount of them. I’m not a fan of their consumer hardware because of how failure prone it is (and how difficult some of it is to work on), but it works for you and you’re happy with it. I wouldn’t fix it if the motherboard diagnosis is confirmed, but if it’s something like the memory it’s usually a cheap enough fix. The service manual can be found here.

I would verify their diagnosis, just to be sure. Take out the hard drive(s) out of the system and run it without that and see what happens. If it doesn’t work, try using completely different RAM - some of the HP systems I’ve had even have trouble with their OEM supplied memory. If it works with different RAM, the OEM RAM has failed in a way it’s rejected by the notebook (despite being the memory HP chose) and you’re dealing with a picky HP motherboard. While it may not work in an HP ever again, it may work in another system if it’s something that doesn’t show up in a extended (8 hour) memory test. Hold onto the module with the expectation the issue will reproduce in another system until visually proven good to avoid a major headache. It may also be a case of a single module failure taking it down due to a mismatched pair the notebook does not like and it no longer boots. Replace both modules to be 110% sure there will be no boot issues due to a module incompatibility or a hidden issue on the “good” module.

However, if you do find the RAM does not fix it, remove the wireless card for good measure. These don’t fail very often, but when they do they fail in ways that are frustrating to diagnose short of removing it entirely (and in some cases, stripping the system for diagnostic purposes). If this is bad, you NEED the service manual as HP has a WLAN WL in their Consumer BIOSes.

Thanks for the reply!

When the store checked my laptop they also tried to replace the RAM, but it still didn't work. I already extracted the HDD and SSD from it and tried to run it but still won't work. I'm going to take it to another service center tomorrow to see if they can diagnose it further. My model is hp pavilion x360 14-ba163tx btw.

Didn't know that HP laptops are like that since this is my first time owning one and they seem decent :/.

Thanks again!

I've known this since the 2007 DV series with the GPU problems. Their consumer machines are the worst offenders when you're talking about consumer grade. If it has a dedicated GPU, they're even more failure prone. The giveaway is if it has dual large cooling plates on the heatsink if you aren't sure about the specs, along with a second chip support besides the one for the CPU. To top the potential for a GPU failure (some boards offer the 940MX), yours also has the chassis you need to gut for service :(.

The business lines that aren't glorified consumer models (EliteBook and HP Z) are good, but you pay a premium for those. The Haswell generation eliminates the WL from the business like entirely on the EliteBook and Z lines (it's gone since HP Z designs most of the Elite line now) as well :-). Not sure about the ProBook, but those are more or less glorified Pavilions in a way. It may or may not be left behind.
