Pavilion Laptop with CPU error code

[1Hellcat]

My HP DV6z 7000 was getting a bit warm so I took it apart to clean out. I cleared out the dust from the heatsink and fan, and reapplied the tim. After getting it all back together, I powered it on and was greeted with a flashing caps lock LED telling me the CPU was no longer working. How can I troubleshoot the laptop to make sure the CPU is in fact dead, and that it's not just a loose wire or something? I just want to make sure it's really dead before I run off an order a replacement.

It may be silly of me but try the next few things :

• See if ram stick are properly seated
• Try to check did you seated your cpu properly
• See if all of the cables lie down ok in their slots
• Check for excesive paste on the CPU socket
• Try a hard reset of laptop by removing the cmos battery out for 15 minutes
• Remove your HDD and try to start the laptop

I hope this will help you a bit. Had a HP Pavilion on a maintenance check a while ago and either you believe it or not he didn't want to start because of a bad hard drive and gave me signal that the CPU was faulty.

Good luck

Last HP laptop I saw with the Replace CPU LED code was a bad chipset on the motherboard due to overheating and poor cooling design.

He had one that was getting a bit warm I hope he fixes it so i can hear what was the problem this time. Cause IMO HP has lost i quality in the last few years in the laptop area.

I tried all of that with no luck. I did find that I wasn't as thorough as I thought about cleaning the old paste off the cpu, because there was some on one of the capacitors surrounding it. Could this have shorted it? I see no other evidence of damage on or around the cpu.

To my surprise, the chipset had no heatsink whatsoever. I don't know if this is common or not, but my old laptop had a little something on its chipset. I guess this explains why the palm rest got so hot.

I think that depends on the models, but yeah a disturbing amount of them have problems with this, or bad connections in the solder pads.

I got a replacement motherboard for the laptop, hooked everything up, and nothing. As soon as I plug in the power cord, the power LED goes on, but the fan doesn't spin and the screen is blank. I tried plugging in another monitor and still nothing. This time there are no blinking error codes on the keyboard. What do you think could cause this, and how can I test it?

So let me see if I understand properly: you had a working laptop HP DV6z 7000, after some time of use, you decide to perform a maintainance on the PC. Disassemble and re-assemble and the laptop doesn't work anymore. Everything is seated properly according to the previous posts. Then, you decided to get a new MB for the laptop (the way of acquiry is not specified in the thread).

Well, beats me. The way I see it, either something is still not installed the way it should be, or you damaged some part of the system. To take apart a working machine and then put it back together and not work sounds strange, especially when seemingly you did everything right. HP's are nasty for maintenance, at least the one I had to take apart.
