Hi,

 

Allow me to ask you for some support on below issue.  I have already tried the serch option, but I was not able to find any similar issue.

 

Wen pluging in the power adaptor the following happens:

- charging led blinking (white)

- power button led is ON

- Caps lock led is ON

- screen is blank,  nothing happens.

- laptop seems to be warm  near the vent area after a while.

 

I have tried removing SSD, RAM, battery, holding down power button for approx a minute for several times...another power adapter,  problem remains.   Any Idea?

 

Thank you in advance!

1. I am not able to test the output voltage and amperage with a multimeter

2. I tried the laptop with my backup charger and it is still not powering.
3. Is there any way to get service on the laptop out of warranty?

4. I assume if it is the  motherboard it will cost almost as much as a new laptop.

5. I have seen a lot of other posts about the Spectre x360 having similar problems.


1. Sigh.

2. It is NOT likely that both of those AC adapters are broken.

3. Yes.  Pay HP, and they will fix it. Or, find a competent local computer technician.

4. In my opinion, you're not wrong.

5. People who do not have a problem do not post here.  So, you only see the "squeaky-wheels", not the satisfied owners.

I wrote the script for resolving 'i' prefixed halt codes earlier this year, but I haven't published it.

I see that you were interacting with @Riddle_Decipher. I'd like to help.

 

Thanks for the reply.

I appreciate your time and effort.

 

Run an extensive test to check if there are any hardware issues.

Refer this HP document to run the test:- Click here

 

Let me know how it goes.

Cheers.

Well, I try to perform HP Pcs Test but... notebook goes into sleep mode. So tests, which need more time then 30 sec were markt as "interrupted". I did not try to update video drivers and BIOS - I have no time to dance whole day around my computer. Yes may be problem is somewhere betin BIOS and Windows. May be somewhere in ragestry. But I did not find it

Thanks for trying the diagnostics. It is clear as daylight that it is a hardware issue as it goes into sleep mode in the F2 diagnostics page also. The computer needs to be repaired.

 

I will send you a private message to assist you with the next course of action. Check your forum private message box in the upper right corner next to the bell icon. 

 

Thanks and have a great day ahead.

For that model you will need to contact HP in your region and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.

 

Contact Support >> http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

 

When talking to the HP rep ask them to escalate your service request.

 

Just to note:

 

Do not try removing the RTC/BIOS battery.  It will not remove the password, but it will reset the clock - as SMC files are time coded, a large disparity between the system clock and the time encoded in the SMC will cause it to fail.
