I got a pc which was in need for an bios upgrade. I downloaded the bios update from the HP site.

After the installation/upgrade from the bios and we restarted te pc we got the error:

ERROR: Unsupported CPU installed
PC will automatically power down in a few second.

The PC is a HP Pavilion a6210 Motherboard: 945gct-hm CPU: Intel pentium dual CPU E2140

We can't get into the bios, try a new bios upgrade from USB or anything

The HP support seems to be going nowhere since all they want is money money money Anyone else had an similar issue? how to restore or anything?

Is that the stock CPU fitted from the factory? – HampusLi Jun 16 '11 at 8:47
Hideously dirty idea of the day: Replace the motherboard bios with coreboot ( perhaps, and then it might work, or permanently brick the motherboard. – Tom O'Connor Jun 16 '11 at 9:16
Must be a wrong display from the bios – A-R Jun 16 '11 at 10:07

I'm not surprised, that motherboard supports;

  • Core 2 Duo (Conroe) up to E4300
  • Pentium D (Presler) up to 960 (3.6 GHz)
  • Pentium 4 (Cedar Mill) up to 661 (3.6 GHz)
  • Celeron D (Cedar Mill) up to 365 (3.6 GHz)
  • Celeron D (Prescott) up to 355 (3.33GHz)

The E2140 is an Allendale chip, so you're out of luck.

hmmmm good one, its a stock CPU so im guessing the bios just displaying the wrong CPU. This is most likely the problem – A-R Jun 16 '11 at 10:03
I'd just call HP. – Chopper3 Jun 16 '11 at 10:04
Exact name from the website is: Pentium E2140 (C) 1,6 GHz which should be supported by the motherboard – A-R Jun 16 '11 at 10:47

Also, before the bios upgrade, it did work – A-R Jun 16 '11 at 10:49
