Here’s what I have:
HP p6531p with a H-R5880-uATX (Aloe) motherboard, dating from mid-2010. Aside from adding a 2GB memory stick about a month ago (to go from 6 to 8 GB), there have been no modifications to the original system.
Here’s what I saw:
Two weeks ago, the computer was in sleep mode (amber power light). I use a mouse click to wake the machine; this time, instead of waking up, the machine turned off. Pressing the power on button did nothing. Unplugging the power cord and waiting a few minutes before trying again worked, and the system booted with the message
"Your system's memory configuration has changed since it entered hibernation. If you proceed, the data needed to resume from hibernation will be lost. To preserve this data, turn off the system power, restore the original memory configuration, and then reboot the system. Otherwise, press <ENTER> to delete restoration data and proceed to boot menu."
No big deal; I chalked it up as a “system brain-fart” and rebooted. I had to reset the date and time.
A week later, the same thing happened, with the same result and outcome. And I started making sure all my data was well backed up.
A day later, the machine was in sleep mode (amber power light on), and when I clicked a mouse key to wake it up, nothing happened. The amber power light stayed lit.
I pressed and held the power switch until the machine shut down, then unplugged the power cord and waited a few minutes.
On pressing the power switch again, here’s what happened… the computer fans ran, the hard drive (audibly) spun up), and nothing else. The power light at the power switch did not illuminate blue as is normal. There were no LEDs illuminated on the keyboard. The optical mouse was not lit. There was no POST beep. The monitor stayed blank.
And that’s where I’ve been for a couple of days. Here’s what I did…
Suspecting a power supply problem, I replaced the original 250 watt supply with a Corsair CX430. No joy; same symptoms. I replaced the CMOS battery with a fresh one; the old one measured 2.8 volts on the bench, so it wasn’t under load. Noting changed.
After perusing this and other boards, I removed all of the memory, disconnected everything – monitor, keyboard, mouse, external hard drive, and disconnected the hard drive and DVD SATA and power cables. I unplugged the USB ports and card readers at the motherboard.
On reapplying the power cord and hitting the power button – no change. I put everything back together.
Finally, using the instructions from the motherboard specs, I cleared the CMOS settings. Still no change, and no joy.
So I’m wondering whether the machine is failing to boot, or if it’s somehow still sleeping (even though the fans and hard drive spins up).
I’d appreciate anyone’s insights on this… have I done everything that I can do? Have I missed something? Did I do something wrong?
Thanks in advance for any replies; the bar is now officially open.
