Hello ! In this video, we will see what it

00:00:02

should be done in case of BIOS problem on an HP brand PC.

00:00:08

As you can see, I start the PC and here, the LED blinks twice.

00:00:20

On the HP site, code 2 corresponds to a BIOS problem.

00:00:27

The first thing to do is to unplug the BIOS battery to flash the BIOS.

00:00:33

We turn off the PC at the button by pressing it for a few seconds

00:00:40

and we unplug it electrically.

00:00:44

I removed the hood to save time.

00:00:47

We're going to remove the battery.

00:00:51

When you flash the BIOS, you no longer need any source of electricity

00:00:57

otherwise the BIOS will not be flashed.

00:01:07

Then we will disconnect the BIOS battery, we will wait a few minutes this way

00:01:19

and we're going to take the opportunity to test it during this time.

00:01:33

We will leave our PC for one to two minutes.

00:01:43

I waited a little, I took the opportunity to test my battery, it is good at 3 volts

00:01:49

so it's OK.

00:01:53

We will reconnect it and we will try to restart the computer.

00:02:06

Despite the BIOS flash, we still have 2 beeps at startup.

00:02:15

We will find another method to troubleshoot.

00:02:24

We will try to restore the BIOS.

00:02:26

To do this, we will keep the Windows key and the B key pressed.

00:02:30

We will keep pressing the power button for one to three seconds.

00:03:05

If that does not work, you will only have to dismantle the PC to order a chip

00:03:16

and de-weld / reweld therefore inter-change a new programmable chip.

00:03:22

I will disassemble this PC, there will be a video specially for the disassembly of the HP DV6 PC

00:03:28

so we're going to end up on the motherboard.

00:03:35

Here we are on the bare motherboard.

00:03:37

The last chance to resuscitate this motherboard is to have to change the BIOS chip.

00:03:44

The BIOS chip is here.

00:03:47

On the Internet, I ordered another one.

00:03:50

Of course, you have to specify the model and type of chip you need.

00:03:56

Before changing the BIOS chip, we pay attention here:

00:03:59

there is a small white dot which means that the chip has a small hole in one place.

00:04:09

It is a marker to put it in the right direction.

00:04:12

It is necessary to identify in which direction the chip goes so as not to mount it upside down.

00:04:21

So we are going to heat up, I do this manipulation with air shotgun.

00:04:34

We are already going to unsolder the old chip.

00:04:45

* removing the old chip by heating it to unsolder it *

00:05:14

We will replace the new chip.

00:05:31

As I said before, you have to put the chip back the right way thanks to the white dot.

00:05:38

* placement of the new chip and soldering *

00:05:55

It only remains to cool and we will test this new chip.

00:06:02

The motherboard has therefore cooled well, we will replace it in its slot

00:06:11

and we will test a restart of the computer.

00:06:23

You have to be careful during this test, I advise you to reconnect everything because

00:06:30

the antennas of the wifi cable tend to wander a little

00:06:41

and can cause short circuits when the card is powered.

00:07:04

Here in our case, the wifi cables are safe.

00:07:17

* reassembly of the PC to test the new chip *

00:07:33

We have the power cable.

00:07:39

We will put the keyboard back to get the diagnosis.

00:07:46

I did not reset the BIOS battery but at least we should have a result.

00:08:11

The PC restarts, the BIOS also.

00:08:16

* PC start-up *

00:08:28

We have a PC that starts without worry.

00:08:33

Now I turn it off to finalize the reassembly

00:08:39

and we will be able to validate that by changing this chip, we can resuscitate the laptop.

00:08:54

I will not film the reassembly, it does not have too much interest.

00:09:01

I tell you right away when the reassembly is finished.

00:09:13

The PC is completely reassembled.

00:09:19

Here there is a little problem to solve because the BIOS is in unlocked mode,

00:09:25

you would have to manually enter the serial number and product name.

00:09:37

The bottom line is that by changing the chip, the PC restarts.

00:09:46

The BIOS chip cost me 16 euros.

00:09:52

For that price, you can resurrect your computer and it's off for a few years.

00:09:59

This video is now over, thank you for watching it.

00:10:03

See you soon :)
