Presario CQ61 Dead- Not Booting

[nogger]

Hi all, although i am an electronics guy by trade my area is normally power supply modules & i have not attempted a motherboard repair before so hoping someone here can advise on this problem.. The laptop is my neighbours, it just wouldn't start one morning & there's no sound & no lights except for the white LED above the DC jack which comes on for a few seconds & then goes off.

I have checked the PSU by substitution & by measuring 19 volts going into the board, i have also measured 5v & 3.3 coming out of the first power chip. So far that's all i have measured while i take time to study the circuit but i have tried a replacement CPU but still dead. Reading on here i see a lot of people mentioning possible corrupt BIOS so wondered if this might be a possibility here?

The CPU i fitted is Intel Celeron Processor W922B591 SLGLQ AM80585900

Where would i go about getting a BIOS image & is the bios chip a i2C device as i am able to program them .

Maybe i am jumping to conclusions though, would be interested to hear what you guys think/advise.

Thanks in advance

Anyone any ideas ?

Hi mate, it should be bios or EC chip.

HI ya...

A shit loads of people are claiming on this forum that the bad BIOS is a cause of no power or actually a cause of every problem...I wouldn't take it that much seriously as it may be million other stuff...Yes the BIOS chip is a kind of I2C device, cause it's actually a SPI EEPROM...You'll need a programmer, which supports SOIC8 (think all CQ61 mobos has SOIC8) package chips...Don't know what You've got exactly, so can't tell if you can't or can programm...I would start with mobo manufacturer number...So we can find a schematic....

Can you please stop using phrases like "SHIT LOAD OF PEOPEL" because you are one of them and its very unprofessional. Thanks

What is the EC chip ?

you do understand that every time a new user or similar that comes here , come with one purpose to fix what stuff they got and that`s it; or come to ask for help because they work in that area and they need help.
they got to learn alot until they will give help to others.

i did the same but i was reading alot everyday until i manage to give some advice. believe me when i tell you that Loser18 knows alot and gives a good point but i see you did not saw it.

READ TROW POSTS FIRST! you will find a way from others that did something similar. we can tell you where to look but now ppl start to ask direct not even say . do you think that a persone here when its telling you to read in other post its rude?

Do a little research then we talk! even you! your not the first and the last that will pick on someone like Loser18.

i will do everything i can to help and even Loser18 because its in mine and everybody`s interest to help and learn alot.

i`ll suggest to try another CPU!
i know it's far-fetched but you have to exclude this to.

I tried the CPU already, mentioned it in my first post. Perhaps the 2nd CPU is duff (bought off Ebay)

EC chip anyone ?

[dj_ricoh]

Re: Presario CQ61 Dead- Not Booting

in order for someone to find a bios dump file we need the whole model:cq61-xxxsa(US)(SE)
but i can tell you that when that`s the problem it will not power up or it will blink on caps lock with a pattern that can relate to bios

Also dj_ricoh, are your comments regarding loser18 aimed at me? I'm confused because you quote cephei328 then seem to be directing comments towards me not researching enough. ? Believe me, i have searched the forum & the rest of Google, that's why i said that a lot of people point to the BIOS as being a common issue. I'm fairly new to motherboards as such having done just 1 Graphics Chip Reflow previously but have over 45 years electronics repair experience & i am active on other sections of Badcaps.

I also have over 15 years in experience in IT support which included hardware & i run an electronics repair business (Ltd company) in the UK. I respect & thank everyone here for their assistance & i'm not trying to short circuit researching the problem myself, just posted on here what seems to be a very common problem. I don't want to re-invent the wheel just utilize the knowledge base on here.

I will post the M/Board number etc here shortly

Re: Presario CQ61 Dead- Not Booting

No!
Loser18 said that and cephei328 came to a other conclusion!

Now to our sheep!
on the back of the laptop there is a model! specific HP code like Cq61-100SA
something like that.
with that code you can go on Hp site and download the latest or the first bios file.
After that you download 7-zip and open the archive inside not OPEN OPEN double click.
right click open inside archive, then you seach inside and you will find some file with.rom extesion or .fb.
those are the raw bios dump files. you take the bios chip out back it up(in case its not the bios) and you rewrite the chip again.
in case the file its not good you will see that the notebook does not even power on.
that means the original bios was OK so you write back the original one and start to poke around and find the real problem.

Re: Presario CQ61 Dead- Not Booting

dj_ricoh, thank you for clearing that up .

The numbers on the base of the machine are:

CQ61-402SA
Also ; WE089EA#ABU

On the motherboard it says:

DA00P6MB6D0
PCB 0P6 MB
REV D

Just to recap on the fault, apart from a white light next to the DC jack which goes off after about 8-10 seconds there is absolutely NO sign of life from the machie. I have tested 19 volts going into the 1st power chip which is a smps controller & measured 3.3 & 5v coming out so i am happy battery & PSU are ok. Tried a replacement CPU, no change & tried it with memory in & out again no change. no lights at all on the front of the machine & fan doesnt spin at all.

Cheers

Re: Presario CQ61 Dead- Not Booting

ok!
this the one!
BACK UP FIRST!
then write this one on the chip

Thank you for the file. Out of interest what is the URL of the H download site ?
I went to this site ; http://h10025.www1.hp.com/ but could only find what they call BIOS Updates ? . Are they also complete images ?

Re: Presario CQ61 Dead- Not Booting

here

then you download the exe file and with 7-zip you open inside the file and extract the .fb file

Thank you , i notice that this is the 64 bit version (from the URL os=4063). The 32 bit version is os=4062). As i can't boot this machine i'm not sure which version is on the disk . Is it still safe to use a 64 bit version ?

Re: Presario CQ61 Dead- Not Booting

no no!
do you understand that this type of programming you have to do it with a external programmer!
i got something like this

[nogger]

Re: Presario CQ61 Dead- Not Booting

You misunderstand what i meant.

I know how to program a chip, i program eeproms regularly (particularly for Samsung TV's !) & these are 24c256 i2C chips.

What i meant was that the link you gave me is for a BIOS where the OS is Win7 64 bit. There's also a link on the site to a BIOS where the OS is Win7 32bit

If i burn a chip using your BIOS file but the machine has 32 Bit OS installed will that case problems.

I guess it will at least show me some sign of life even if the OS is wrong.

Re: Presario CQ61 Dead- Not Booting

no no no!
it refers if you use the exe file when machine its working! just to update to the latest bios.
if you use external its irrelevant because the raw file its the same
