I don't know if anyone else has seen this or not, but I thought I'd at least make you aware incase you come acrossed it and you can narrow down the problem a fair bit.
We've had 5 of these over the last couple of weeks come in with the same exact problem. Event Viewer is showing Microsoft-Windows-WHEA-Logger Event ID: 18 all over the place. Clients are complaining that the laptop is getting super hot, but not BSODing like it should, or restarting. No no no...Clients are using the laptops the whole way through until 1 of 2 problems come up upon boot:
1) Lights come on, but nothing happens
2) Lights come on, and it beeps like mad crazy
The CPU appears to be getting more voltage than it should be getting (near or above 2V). AC adapter checks out fine, so does the battery. It doesn't matter if it is on battery or on AC, with or without battery, the issue is the same. The BIOS turns out to be the culprit, not managing power correctly at all. Re-flashing the BIOS wasn't an option for 3 of them, the CPU's had already failed. On 2 of the laptops, re-flashing the BIOS worked, but only got a few more days out of them before they failed. I contact DELL, they said to just re-flash the BIOS...thanks Dell, that sure helped...The best you can do is check the laptops in BIOS and make sure they are applying the correct voltages, and re-flash as needed. Yesterday I checked out another client who has 10 of these laptops for his office, 4 of them were sitting at a voltage of 1.5V going to the CPU, after re-flashing, they dropped to ~0.8V at peak (which is what the other 6 were sitting at) and actually began running smoother than before. The temp sensors aren't reporting the correct temperatures (there is no way the temp could be negative in Arizona) in the systems with the over-voltage, what crap right? So that might be another sign to be concerned/looking out for. Once the BIOS is flashed, temps and voltages have returned to normal operation.
