HP Pavilion 17-f136ds Black Screen Caps Lock Constant Slow Blink

HP Recommended
Pavilion 17-f136ds
Microsoft Windows 10 (64-bit)

Yes I changed the CMOS battery on a Pavilion 17-f136ds after the computer power button wouldn't light up. Now the button lights up but I get no screen no fan no access to dvd drive and the caps lock continuously lights up at a slow pace. Please help should I try taking out the RAM and putting in the other slot or replacing the RAM altogether or my laptop/notebook finished??

The CMOS battery only maintains the UEFI/BIOS settings when the laptop is powered off.  It has nothing to do with powering any of the components, including the power button.  The components are powered by the regular battery.

 

Whenever you change a CMOS battery, you should always be sure to reset the settings to the default before you do that.  I'm guessing you did NOT do that, right?

 

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
If the CapsLock key is blinking or there is beeping, read this HP information on the likely cause of the hardware failure based on the blinking or beeping patters.

For laptops, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/c01732674?jumpid=reg_r1002_usen_c-001_title_r0001
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number:
Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"

Case number and contact information appears.
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not get you a useful page, then use the main HP link:

Good Luck
