Hello SuperMario1,

 

Thanks for your response.

 

The last thing i did, remove CMOS battery and after a few minutes i plugged it.

Then connect AC power adapter and press power button.
Laptop starts but gives a error message

 

"The CMOS checksum is invalid, The BIOS will be reset to the default configuration and will be rebooted."

:)

Finally laptop start normally. It works fine ...

 

But same problem when i restart

"blank screen caps lock blink 2 times every 3/4 sec"
:(

 

So finally

1. remove CMOS battery and after a few minutes i plugged it again

2. connect AC power adapter and press power button

3. laptops starts normally (with a error msg same as previous)

4. Upgrade bios to F.29(previously i had F.24)

5. Everythings works fine (restart/shutdown have no effect)

 

:) :) :)

Hello nirupam_duet,

 

Welcome to the HP Forums! I hope you enjoy your experience!

 

I understand the computer has a BIOS corruption failure. If you followed all of the troubleshooting, then I would encourage you to contact HP phone support. They may have to service the computer to resolve the issue. You can utilize this website to learn how to contact HP appropriately, based on your region: Contact HP Worldwide

I'm having the same problem now. After doing what you said, the computer booted up successfully. however, i realized my bios is already f29, so i thought i didnt have to update it, and then i restarted it to see if it can boot up again.

It's not booting again.

Only this time, unplugging the cmos battery and wait a few minutes and put it back doesn't work anymore. I then tried boot it up without the cmos battery, it booted up showing the bios will be reset info, then when i hit enter it still won't boot. Now not matter what i do, with or without the battery, my laptop stays dead with capslock blinking twice every sec.

 

Anyone have any suggestion?

 

[UPDATE]

somehow i used the cmos battery trick to get it booted into windows again. but it won't boot if i restart - i need to use this trick everytime to boot up. I'm not sure if i should reinstall the bios driver since 1. its already f.29 and 2. i dont know whats gonna happen if i update it needs to restart and it fails to boot up and brick my laptop permanently. So, still need help!

I had the same problem, but after removing the keyboard and the hard disk and putting them back again, the laptop came on. It is working well now.

Re: Blank Screen; Caps lock Blink Twice Every 2/3 Seconds with orange wireless button.

I had this exact problem. Display not switching on and Caps Lock light blinking twice.

 

I opened up the back, and closed it again!!!

 

I did some digging around and found this page:

 

http://support.hp.com/us-en/document/c02693833#AbT1

 

It gives full instructions on how to create a boot up USB with a new BIOS on it.

 

I followed the instructions on another laptop, inserted the USB stick into the broken machine and booted it up.

 

To my astonishment it worked!!!!

 

Hope this works for you too :0)
