I cannot recover my bios password could someone help plz?


Hi,

Most motherboards have a jumper switch usually situated close to the CMOS battery. The jumper usually connects over 2 pins with an open pin next to these. By moving the jumper over to the open & center pin you will reset all BIOS settings, including your BIOS password. Move the jumper back to its original position before turning your PC on.
In some instances you will find no BIOS jumper. In such a case you can clear the password by removing the CMOS battery from the motherboard for a few seconds and then replacing it.

Best wishes,
Graemevm

Emachine ET1810 is not powering on already replaced the power supply


You may have a bad Power On switch. The Power On switch is located inside the plastic Power On button.

This is a generic ATX power on switch, that I have found works in many computers,

http://www.directron.com/atxswitch.html

Have you bypassed the Power On switch?
If you bypass the Power On switch, and the Power Supply comes on, you have a bad Power On switch.
If you bypass the Power On switch, and the Power Supply does Not come on, you have a bad Power Supply.

Sometimes a new Power Supply can be bad.
Make SURE the ATX main power cable is plugged in tightly.

(I have had an instance recently where I bypassed the Power On switch, and the Power Supply came on, but only as long as the jumper wire was in place. Remove jumper wire? Power Supply went off. Removed the jumper wire, then pressed the Power On button. The Power Supply came on )

Bypassing the Power On switch has nothing to do with the switch itself, or the wires to the switch.
A jumper wire is used in the connector for the ATX main power cable.

My sources indicate the ET1810 uses a 24-pin ATX main power cable.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

A jumper wire is used to connect the Green wire (Soft Power On. Also abbreviated as PS_ON) to ANY Black wire. (ALL Black wires are Ground wires)

Looking at the photo to the far right, you will see the Green wire goes down into a socket hole.
This is the Back of the connector.
The jumper wire goes down into the socket hole RIGHT NEXT to the Green wire.
The jumper wire has to go down into the socket hole pretty far.
(Approximately 1/2 inch)

At the end of the Green wire is a metal terminal. The jumper wire has to go down into the socket hole, far enough to touch that metal terminal.
Same thing for ANY socket hole with a Black wire.

(The Green wire is the Soft Power On wire. It is a 5 Volt DC wire. The Black wires are Ground wires.
The jumper makes a circuit from the Soft Power On wire to a Ground wire)

The jumper wire usually preferred is a paper clip straightened out, then bent into a U-shape.
The middle of the U is wrapped with black plastic electrical tape.
This is where your fingers hold the jumper wire.

One end of the jumper wire goes down into the socket hole with the Green wire.
The other end of the jumper wire goes down into a socket hole with ANY Black wire.
The contact is no more than 2 seconds.


My sources indicate the motherboard is an ECS MCP73VT-PM

Somenon put a power on password on a hp desktop DC7900 PC


Turn the unit off. If you open the unit there will be a jumper to clear the CMOS and a battery. Remove the battery and then switch the jumper as silkscreened on the board. usually there are 3 pins currently crossed are 1 and 2. switch it to 2 and 3, press the power button then hold for a few seconds. unpress the button and remove the pwoer cord. press and hold the power button again for a few seconds to clear all power. reconnect the jumper to 1 and 2. put battery in and plug and boot. password should be gone.

in some units there is a "clear password" or "cmos password" jumper. crossing this will remove the password in those units.

I am looking for the specs for a motherboard for a t2862 emachine, more specific for the connection from the mother board to the on/off switch


This is a link to an UN-Official eMachine website: http://www.e4allupgraders.info/ . I found your motherboard but NO info on the jumpers. It is an Intel motherboard but they're website has no info either. So, on the right side of the eMachine page there is a eHelp Forum. They should be able to get the right pins for your power switch.

Need wiring diagram for eMachine 20030812 motherboard!!!


You should be able to see the words/letters that go with the jumpers on the motherboard itself. look around the jumper settings area for power, pwr etc. and match them up with your jumpers which should have what the go to on them.
