Success - HP Spectre X360

Status
Not open for further replies.
I don't think it is a hardware problem because the display works fine sometimes and sometimes the issue appears. If it was hardware, well it should permanent.
Also, when I use a second monitor, I never see this problem in the second monitor. So, I assume it has nothing to do with the graphics (hardware I mean).
The original author of this guide has a 15" HP Spectre X360 i7-7500U / HD-620 / GTX 940MX. However, mine is a 15" HP Spectre X360 i7-8550u / HD-620 / GTX MX150.
Could this be because of the CPU difference?

I see the power light, then the caps button start blinking 5 slow blinks, followed by 3 quick ones. I checked on the HP website and found this.
The EC timed out while waiting for the Bios.
I followed their suggestion (remove peripherals, and reset laptop) but nothing worked.
I am truly stuck now. I can't sent my laptop to hp support because I live in a place where there is no HP support.
Any ideas?

@ktobah,

The flashing Caps-lock led is indication that the BIOS has detected a hardware problem
I've never seen that behaviour with my Spectre X360 .. it doesn't sound good.

About the only thing i could suggest is to do a full SMC / EC reset ...

You'll have to remove the back cover (there are two hidden screws under the rear rubber pads)
Once you have the rear cover removed use a small flat head screw driver to gently prey the battery power connector from the motherboard, once you've done that open the laptop and hold the power button for 30 seconds to discharge any residual power in the system this should clear the SMC. With this done reconnect the battery and re-fit the rear cover.

Try powering up the laptop and hope for the best.

Hope it helps
Cheers
Jay

Thank you very much. I have actually solved that problem with a CMOS reset.
After Rehabman mentioned it might be a hardware issue, I went on a searched online. I find out a lot of other people who owns the same laptop complaining about the same flickering issue!!
Well, I guess it is not a software issue anymore. Disappointing.
Thank you for your help.
 
@jaymonkey, thanks for the great info.

One thing I've been trying to verify amongst all the x360 threads I find is external monitor support. I'm thinking of getting the 15" Spectre x360 with the i7-8550U and Nvidia GeForce MX150. I understand the Nvidia may need to be disabled which is fine. However, I want to make sure I can connect a 4k display at 60Hz be it through the HDMI port if possible or through the USB C/TB3 port with an adapter for either DP or HDMI 2.0. Have you (or anybody reading this) tried this by any chance? Thanks again!

@crayonshin,

HDMI Video and Audio are all working fine on my 2017 HP Spectre X360, I have 1080P external monitor so can not confirm if it works with 4K but as long as the port specification and cable you use is 4K compliant I can't see any reason why it would not.

Running at 60Hz on internal 4K display ....

I don't have any TB3 capable displays so can't comment on if that works or not.

As with most laptop hacks you will need to disable the Nvidia DGPU once that done its pretty straight forward with minimal static DSDT patching required, the rest of the AHCI patching can be done with SSDT HotFixes and Clover AHCI renames. Replace WiFi card with DW1830 (BCM43602) and use Lilu + WhatEverGreen + AppleALC + AirportBrcmFixup to patch MacOS.

Awesome, thanks for the info! Hopefully I'll be trying it out next weekend provided Best Buy has enough Black Friday stock!
 
How's the stability and battery life, and does the SD read work? Thinking about hackintoshing my 2017 15" since I need to be more familiar for working with other photographers
 
Should note I'm still on High Sierra, not Mojave, but the results should be somewhat similar, minus the differences laid out at the beginning of the thread with APFS.

After some tweaking of settings, I can get 4 and a half hours battery life on it in heavy use, with 30 tabs, Photoshop, Tweetbot, Atom, and other things loaded. I have a large Dropbox folder and it can make the fans spin a bit on boot. I'm mostly a writer but do some photo editing/graphics and web development on it. But the x360 is good as a Hackintosh daily driver; I only occasionally have glitches—most often in the form of the machine crashing in sleep mode.

You will have to replace the Wifi card to something Apple supports, but it's doable on the 15" x360.

I've never gotten the SD card working on it, in part because internal SD card support isn't really a thing on laptops. See FAQ: https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
 
Hey @jaymonkey, was curious if you ever worked out your issues with the touchscreen in Mojave. I'm finally doing the upgrade (on an external SSD to start, with plans to do it on the main device if it goes well) and there doesn't seem to be a lot of Mojave-specific info on the touchscreen situation.

Also, I realize this thread is a few months old, but if it helps for folks just getting into this: AppleALC works, though I'd recommend mapping to layout 1 rather than layout 3, as I get scratchiness from the speakers on that layout.
