Hp 8000 Solid Red light


desktop small form factor, SFF, (not silly fat frog)
no statement as to where lamp is, I'll guess, FRONT.
just the light bothers you, only..?
why not RTM read the manual to learn what it means.?
so where is said LED lamp, ? front of case on the SSF case?
HP calls it, and searches only work with this.
HP Compaq 8000 Elite Small Form Factor PC./
im reading your manual now for you at HP.com
my guess is lamp 5, (pwr) is not green now but is red
green means power ok, red means, not ok.,
page 2:
if flashing , the flashes are codes, what is your flash code if flashing
if not this LED then say which one?
green on 5 means ok. power ok, no errors. red bad.

yes it should but it could also be hdd or memory or processor or the led are connected wrong on the mother board so I suggest that you take your time and pull down that pc and make sure you follow the necessary safety precautions and look at the mother board and fit it up slowly ok

If the red light on Compaq Evo D510 P4 keeps on blinking and the PC wont start when you try to power your PC then whats the problem ?


Power Supply.

Weak voltage power rail, or more than one.

(There are three power rails for the Power Supply used in your computer;
1) The 3.3 Volt power rail
2) The 5 Volt power rail
3) The 12 Volt power rail.

Wires with Orange insulation carry 3.3 Volts
With Red insulation carry 5 Volts
With Yellow insulation carry 12 Volts.

Each wire is connected to one power rail in the Power Supply.
{All Black wires are Ground wires}

The Power Supply in your computer is an SMPS. Switched-Mode Power Supply,

http://en.wikipedia.org/wiki/Switched-mode_power_supply )

I don't know what form factor your Power Supply is because you didn't state which model it is.
Small Form Factor (SFF)
or
Convertible Mini-Tower
or
Ultra Slim Desktop

Post additional questions in a Comment. Also state what model your Compaq Evo D510 is.

Regards,

Simply blink red light in front or power led light ,no display anything .power on button is on blink red


Try to do a Hard Reset. Disconnect all peripherals connected from the unit (power adapter, monitor, keyboard, etc) then press and hold the power button for around 15 seconds. Plug everything back then power the PC on.

Hope this help. Goodluck!
