Hp 630 Core duo ddr3 no post annymore

[dellxps15]

hi, i got this laptop with no display.

it has the chicago board core duo version with ddr3.

i have changed the intel nortgbridge with integrated vga in it, and after put this new bga, pc boot telling me some cmos error found ( i forgot to connect the 3v battery for testing).

i thought it was a cmos battery message error, so today i put almost all together and when i go for boot, it give me this message and then no more display come.

i think it was some bios, but the only chip i can find is ui3 that is a winbond w25q16bv (16mbit chip).

on the hp site there are 2x4mb and 1x 2mb inside the bios hp exe. tried with one 4mb version but no more Ec light.

on other thread i found ec bios dump for the hp 630. flashed it to that ui3 and now light comes on, but if i press power botton pc start blinking and no display.

where is located the bios chip ? really cant find it in that mainboard.

is ui3 all in one ?

any help would be great , as that notebook after rework started with these cmos error, but i was able to get display.

the wodoo dolls inside notebooks saga continues...

Re: Hp 630 Core duo ddr3 no post annymore

would you be so kind to post motherboard code so that i can try to find correct bios

also, always backup old bios, even if its not working :/

Re: Hp 630 Core duo ddr3 no post annymore

tnx for reply. finally i found original bios in hp_tools hard disk partition, flashed it but i have the continuous blinking caps lock like chipset bga rework didnt go well.

here is the board code.

if you still have old dump of original bios load it to any hex editor and scroll at the end of file and you should see something like

what you need is $BIDXXXXX that is board ID and afterwards is a version of bios

i have prepared (decrypted and splitted) main bios and ec for all 3 versions of bios for 3 versions of matherboard put in this laptop

hope it helps
and you need to rebuild dmi data

edit:
by looking at your post again, you have w25q16bv (16mbit chip) = 2mb, so your board id should be BID03676 and eprom 2mb... flash that file first

hope it works

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

that was the bios inside my hard disk folder. 3676.

maybe i can try with another bios chip ? i have sst 16mbit bios new...

if i look here http://forum.thebgareworkmachine.com...ic.php?f=8&t=5

mine is w25q16bv, similar to W25Q16VS
and i have new SST25VF016B chip.

all this however make me think rework gone wrong..

[ala_borbe]

Re: Hp 630 Core duo ddr3 no post annymore

have you verified after writing to eeprom that its written good? sometimes eproms are faulty, sometimes chips are specific and do not work as it should
i have a lot of troubles with 25x16 but 25q16 works always on my both programmers

and yes, that sst should work too

bad bga rework cannot be excluded also, dono how to check that :/

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

i dont understand why after rework, pc just post fine to screen warning on cmos factory reset needed. and i power it off as i got screen and bga was fine. tried to boot 3 times and all 3 times i got the warning logo, but pc was alive. last time i tried to power it on, it give that cmos error and i let it do what it wanted to do, so pc restarted and from now going on, no more post to screen or hp logo...



ps: im going to try this other bios chip

ps: ofcourse after i write bios, programmer verify tell me all was perfect.

Re: Hp 630 Core duo ddr3 no post annymore

i,ve changed bios chip, but it's all the same. pc power on, then off. then on again and caps lock start blink continuosly.

cpu is cold and didnt warm up even if voltage are present.

[Th3_uN1Qu3]

Re: Hp 630 Core duo ddr3 no post annymore

Looks like the NB is either bad or it hasn't soldered properly. I've stumbled upon that a couple times too. It runs after you rework it while the board is still warm, then after it cools down it no longer works. It's always BGA related.

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

chip was new, do you suggest to do just a reflow,reball that chip or go for a new one ?

tnx very much for help

PS: pc was booting for one day. so i suppose it's not a cool down.

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

today i put back the old reballed chipset and still the same... :|

continuous blinking caps lock. i think i have to check all voltage for chipset...

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

cant edit, but i cheked all chipset voltage and all were ok.

only thing i notice is that hdd doesnt spin when i power pc on. pc stay on but no hdd spinning.

plus there were 2 resistor down chipset tht moved a bit because of the thermocouple. put them back in place in the hope of a working laptop but still the same.

all voltage present at coils, but no hard disk spin and no post. only continuous blinking caps lock

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

today i check rsmrst, plt_rst, h_pwrgood and all are ok.... 3.3 volt on each of this... so it it a bad nb-gpu chip ?

this laptop has intel chip with integrated intel vga.

[dellxps15]

Re: Hp 630 Core duo ddr3 no post annymore

well here i am again. after tried 4 new bga, reballed also sb, still the same.....

could it be a bad kb controller ?

i checked also all voltage and all are present.

[tata123]

Re: Hp 630 Core duo ddr3 no post annymore

is the CPU still cold? could also be the CPU controller (most ISL) or near the CPU controller the smd (resistors).

I had this problem on Samsung i5 Mainboard...

Cold CPU's most failure on Northbridge, BAD caps, broken CPU controller, BIOS,
