Novatech A15A

[dj_ricoh]

Hello fellow technicians

i got this notebook from somebody.
it became mine, so i will like your brain if you can help me to solve this puzzle .

the board code its in the picture.
i can`t find any schematics for so if you got one please share it.
p.s. i saw MSI uses this board to.

let me begin .
somebody try to change the screen and ... yes they are not PROS.(connector pic)

-there is voltage on power button and it goes down when its pressed.
-no voltage on bios.
-nothing its heating.
-if i take the bios battery out and i insert the adapter its auto starting.

I can swap the the LCD connector but i will try to fix it before.

I never try to install ram on it but i`m 95% it will boot because i saw this case once but i did not even knew how to solder properly then.

the Q: did you saw something like this? was the kbc bad?
thank you

Re: Novatech A15A

anyone can help me with some info where i can find some data for this npce783la0dx?

maybe i can find some data in another schematic.

Re: Novatech A15A

the only think i found its that NPCE781LA0DX can be replace with NPCE783LA0DX(mine)

and NPCE781LA0DX can be found in Quanta ZQ1 Acer Aspire motherboard.

Here

it shuts down the board if i press power button but it does not power it back.
that`s what i need

Re: Novatech A15A

i install a memory on the board and the BD82HM65 and the Memory(ddr3) are super heating up.
yes the memory in the slot!
dammm! there is no display

Re: Novatech A15A

i just saw now why its hard to find a schematic for this board!

there are no marking on the board! 0 marking only jumpers

That's why you need boardview as well...it's pegatron mobo & I doubt you'll find any...I couldn't even find a schematic...Did you check resistance @ all coils?
And remove that fucked up connector before you power it up...

yes! I will take that socket out and not power until then.
I don`t get why its heating up the MEMORY! 1gb of ddr3 LOL

Re: Novatech A15A

Maybe bad mem, shroted slot or something on ddr rail...clean the socket with ipa...It may help...without schematic it's really hardcore (at least for me) maybe some pro would fix it even without schematic...

BTW did you check the resistance and voltages at all coils?

Re: Novatech A15A

i check they all 14Ohms and 2 with 18Ohms and 2 with 2-5kOhms.
brb i`ll check the voltage

Those with 14 & 18 ohms indicates short somewhere...think that's too low, mate...But check voltages anyway...

Re: Novatech A15A

i`ll try to do a MACRO pic so i can map the board ohms voltage and how the trace go

Re: Novatech A15A

without cpu the power led just Blinks once every 2 sec.

Is it a sandybridge?

Re: Novatech A15A

SR04B (Intel Core i5-2410M) do you belive me i don`t know them :P
until c2d then pff lost
ofc i know them in general ivy sandy cherry wtf

Re: Novatech A15A

"until c2d then pff lost"

WTF are you talking about?...Missunderstood this one...If you mean star wars it's R2D2, lol...

Ok! let`s leave the Republic out of this ... they use the force to repair stuff .

Re: Novatech A15A

ok got the generic pictures.
brb i`m probing

Re: Novatech A15A

Can't even find SIO datasheet...
Found schematic of Acer 7250 with NPCE795LA0DX...
The weird thing is that hardware spec & config sheet says there's 794...Maybe the pinout is the same...


& post those voltages...

Re: Novatech A15A

that fet in the picture with short i`ll take it out tomorrow so i can see if there is short on pad or fet

[dj_ricoh]

Re: Novatech A15A

its there a pin to verify that has the same pin layout?
