Pavilion DV5 1111ea CAPS lock and NUM lock continuously blinking

I recently upgraded my dv5 pavilion 1111ea to windows 8.1

Due to an issue with the OS, it doesn't resume from Hibernation, as described here.

I held down the power button until the laptop swithched off.

Once I tried to put it on again, it couldn't get to the BIOS screen, the CAPS lock AND NUM/SCROLL lock LEDs were blinking continuously, once every 3 seconds.

No disk activity at all.

I checked HP Notebook PCs - Blank Screen LED Error Codes but non corresponded to continuous blinking.

 

I have a spare CPU which I removed from a discarded dv5, the CPU is exactly the same model with mine (AMD Turion x2 RM-72).

I've troubleshooted by removing both RAMs and testing each individually in different ports, yet no solution.

 

I'm suspecting the CPU because about a year after purchasing the PC, it began to overheat and hibernate automatically to prevent the CPU from burning. I had to underclock the CPU so, for over three and half year now, I've been running at 50% CPU speed. In total the laptop is 4.5 years old already. :smileywink:

 

Please I need suggestions as to what to do. I don't have the required tools to replace the cpu myself.

Thanks.

Hi,

Please try a hard reset and see if it works.

1. Power off your laptop
2. Remove the a/c adapter, battery and everything that is attached to your laptop.
3. Hold the 'POWER 'button down on your laptop for about 10 seconds.
4. Plug in the a/c power supply (without battery) and power on.

Regards.

Hi,

thanks for the reply,

I've tried that earlier, it didn't work.

I also removed the CMOS battery, didn't work either.

So, I replaced the CPU with a spare that I removed from an abandoned dv5.
It didn't work, though I don't know if the spare CPU was damaged or not.

Re: Pavilion DV5 1111ea CAPS lock and NUM lock continuously blinking

I took my PC to a repairer and he claimed to have replaced the CPU with an AMD Sempron from his collection of scrap laptop CPUs.
After about 3 months, the same problem has recurred.
I opened it up, only to find my former CPU model inside!
Whether the repairer had a spare Turion, or he only performed a trick to make my original CPU to work (and billed me for a replacement), I can't say for sure.

Now I've purchased another CPU from eBay.
Fixed it and...... got dissapointed again.
Still blinking the CPU error code.

From other posts I've come across here, I think HP/AMD combo is to blame for all these.
