Hey there! I have an HP 15 ab584tx. It was working totally fine until last week. Now, it doesn’t turn on for more than a couple of seconds, sometimes just a second. It turns on and then, immediately turns off fully. All components turn off, even the power input port light goes off for a second, before coming back on. Sometimes it even makes it as far as the windows desktop screen and works fine for a minute or two, before randomly turning off again. It also sometimes gives me an overheating warning on boot(but doesn’t really overheat, more info below). Here’s what I’ve tried so far: Removing the battery, draining any static power and plugging in the AC cord. Opening it up and cleaning it fully, repasting the CPU and GPU. Systematically removing each component and testing(each RAM module in alternating slots, HDD, CMOS battery, DVD drive, display unit,WiFi card). Entering the BIOS and letting it idle. (goes off after a couple of minutes here too) Checking the temps and fan air flow. (normal) Checked each cable for loose connection. // Everything I’ve tried yields the same result: the laptop turning off after a couple of minutes. I checked the temps via HWMonitor, which I managed to somehow install before it shut off, it was around 45-60 degrees overall, nothing concerning. During another boot I managed to install CPUZ and check the hardware dispalyed and everything looked perfectly fine(showed both the iGPU and Nvidia GPU and all 16GB of RAM)There was no physical damage to the laptop either. I’m really lost as to what exactly is wrong with it. Since I’m in a high risk COVID zone, I can’t go to any service centers for a long time. Any help/input is greatly appreciated!
Hi @iusman290 , It’s a pity that you don’t have a multimeter as you could have used it to prove whether there is an intermittent connection in the power connector port or not and also to test the charger voltage. Do you have access to one or know anyone who has one so that they can be checked? Again this is only for elimination purposes but it would be a shame if you spent all your time trying to find the problem and it turned out to be the power connector or the charger. Anyway not that you need it but here’s the maintenance and service manual for the laptop, taken from this webpage. Go to p.69 and you’ll find the power connector cable removal procedure and more importantly the part number. If you do need to replace it, search online using the part number only in the search term of your browser to find suppliers of the part.
I’m having the same issue. What I have found so far is the battery charges (new battery). When I have the pc plugged in does the same shutdown. When I run it only on the battery everything is normal again. tried my other HP power supply and same issue. When I boot into the BIOS and run the diagnostics on the laptop all is good and wont shutdown at all while plugged in. SO… I conclude it’s a windows feature. not sure what it is yet.
Try replacing the power adapter, and hope for the best - the HP “smart” 65W adapter these 15-X machines come with is so light I have a feeling they are cheaply built internally. Try and get an OEM 90W, or a 65W - I personally use the travel 65W on my HP laptop (840 G3) and I’m happy with it. The ab laptops can run on a 65W no issue due to the low specs if you want to save a few bucks. DO NOT buy another one of the original 65W “smart” adapters, even from the HP store (Spare# 714657-001). They are hot garbage! This is the one I use (paid $41):
HP Travel Power Adapter (65W). Alternatively, look into the 90W version. I do not like the “smart” adapters due to how light they are, and their tendency to prefer power savings>power means they age badly and fail in weird ways. Unless the 65W is on sale at a very healthy price cut I do not recommend it as it is usually only $10-15 cheaper in most cases. It was ~$41 for the 65W vs. ~$65-69 for the 90W when I got mine. The 840 G3 can use the 45W as well which I know about because I had to buy one to get by while the HP purchased unit was delayed for days. If for some reason the power adapter does not help, then you may need to replace the battery, or run without it - these are old enough batteries are beginning to wear out.
Maybe try to flash the bios to the latest version by using an external flasher for example an e3 flasher
Hi, This case happened to my DELL once. And I abandon it gradually.
You should just pull out the motherboard and see if you can find visible burn or burnt marks on the motherboard to see if its shorting when component is in use, Or you should just do a full run down on the trouble shooting guide on how to find the problem and fixing it.
