Yesterday, I've encountered a problem - my beloved notebook restarted and was caught in bios boot loop. After unplugging the AC adapter and removing the battery I've managed to boot back in the Windows, but that problem still exists.
If I enter BIOS, or if notebook spends some time chillin', before OS kicks in, it reboots?! Only help for now is to remove any power source and recconect it back after a few minutes.
Would anyone know where the problem might be?
ps. I removed HDD just to test boot loop, and soon as message about no valid boot media shows up, it reboots (sometimes after 5-7s).

My HP8510w wont reboot (it switches off and starts to boot again.)until it cools down. And I've got this exact same problem on two HP8510w. I just put up with it by letting them cool down for 5 minutes. Strange is once it gets into Windows it does keep running OK.
But today I was trying to install a SSD. And both kept cutting out very quickly just could not complete the Ghost restore before it cut off. I raised the keyboard and felt CPU and it was very hot. I placed an ice pack on it and it ran OK. So it seems for some reason the CPU heats up to much very quickly whilst booting, but once running WIN XP it keeps cooler. So I'm guess maybe it is something in the BIOS is setting the CPU to run really hot somehow. So if the CPU is running very hot, it will keep tripping out on a reboot. Of course doing a restore it takes much longer to get to windows via the CD boot. I am running BIOS V14 and there is now a release V20 on the HP driver web site for th HP8510w. But apparently you cannot roll back the BIOS to earlier version once you go to V.20.
BTW: I did clean out the fluff n stuff from the fan and the fans always on. So its not that. I've not yet upgraded to BIOS V.20. But the realease notes etc don't mention the boot issue.
Any way I'll try that next.

OK, now I've loaded BIOS V.20 on both PC's and no change. I also reapplied thermal paste to the CPU & GPU. As it only has the shutdown issue before before it loads the OS, WIN XP in my case. So its got to be something in BIOS? Maybe the CPU overtemp shutdownsetting is set to low? I can get the PC to run in BIOS mode for long periods by keeping CPU cool. I keep the CPU heatsink cool by placing a large Alu block on top of the CPU Copper pipe with a bit of thermal paste. The CPU doesn't seem to get that hot maybe 65deg C ie without extra heatsink on top. I can place my finger on it for a few seconds. So something is wrong. I just wonder if you could manage the CPU overtemp setting somehow? As far as remember this issue started after a BIOS upgrade. It may have been passed over as if manage to get out of BIOS mode quickly and boots straight into the OS the PC will run forever no problem. Really strange. As its happening on the two HP8510w I have I don't think its HW related.

Hi there! I wonder if you have found any solution to the problem?
I started having exactly the same problem just a few weeks ago on my 8510w. I also tried updating to V.20 but that didn't help. I also tried resetting my BIOS configuration but nothing changed - my laptop kept restarting itself.
It is indeed weird that the processor overheats while booting as the fan is running... Smells like a BIOS bug...

@Kyle_W , it's an HP Compaq 8510w.
A friend of mine pointed out that it sounds like a common soldering problem in the chipset in recently produced electronics and a part of my chipset might need reflow slodering.
He also said that, if that's the case, the interval between reboots might become shorter and shorter over time until I won't be able to boot any operating system.

I don't thiink it's a solder ball issue. That's was a bug due to bad thermal design of the NVidia chip or bad implementation of the chip by HP to it's motherboard. My son had the "no video" issue on his HP DV9000 laptop PC just out of warranty whilst he was serving in the US Army in Afghanistan. HP refused to repair it unless he paid big bucks. I did try re-flowing the Nvidia chip with a temp controlled Hot air gun, which worked for just a couple of weeks. HP had cemented around the Chips, so the chips would not float back down on the solder balls. another design screw up by HP. As it takes about 2 hours to strip out the Mother board, (another really bad HW design) and because of the cemented chips I did not settle I did not try reflowing again. Funny I used to work for HP in the 1970's -1980"s. A wonderful company that sadly lost its way, the HP Way of Bill Hewlett & Dave Packard. Basically HP & NVidia hung the customers out in the cold with these badly designed laptops. Would have never, ever happened under Bill & Dave. They once bought back every MID sized Computer system launched in the 1970's when they found the design was flawed and it had been released to early.
