Re: hp pavilion zd 8008ea no charge

I have been looking for BE443L when I have time but I have only found hints that it exists. (No data.)

Can you provide a better picture of the logo?
Maybe I can determine the manufacturer with that.

Re: hp pavilion zd 8008ea no charge

hi PC BONEZ
You don't have to look for BE443L but you have to look for 4407
I have made a search and I have found that it is equal to the AP4407M sold by WWW.PARTMINER.COM
Me however I wanted to know from some holder of the ZD6000, if changing the 4 ICs has resolved
THANKS

Re: hp pavilion zd 8008ea no charge

I was looking for 4407 too. All I could find was lists that include that number.

I'm not sure how you determined that is the right part.
There are a lot of similar parts and the specs aren't exactly the same between them.
http://www.hkinventory.com/public/Of...t4=0&datecode=

The logo may indeed be AP but I don't see an M after the number.
I think AP4407 is the entire PN.

AP and APEC are the same company for this part.
Advanced Power Electronics Corporation (AP, A-POWER, APEC)
Their site is slow enough it might be faster to walk to Taiwain to get the PDF file.
I haven't been able to get it. Maybe you can.

Hope you don't mind the repost of a lager image marketta.
For pc bonez



I couldn't seem to find the logo

http://www.dialelec.com/semiconductorlogos.html

Chip doc has 3 pages and I use to have a site but no idea what happened to the link

cheers

Re: hp pavilion zd 8008ea no charge

did find this PDF HERE

is that Anachip?

From a post on this forum thread Here

So seems 4407 is a common package Mosfet and I suppose if 2 are fried
the question becomes why did they fry ?
what other damage my have occurred and will replacing all 4 (to be safe) fix it?
(4407 you learn something new everyday)

(pinout matches PCB layout by the looks of it)


Hope the above is of some help

Cheers

Re: hp pavilion zd 8008ea no charge

See that's the problem.
4407 parses to a whole bunch of different parts.
In one search I did AP4407M came up with a MOSFET Controller 8-pin chip. (All I could get, there was no data sheet or links.) That makes sense but as his chips don't have an "M" on the end it may not be for the right current, voltage, or switching frequency.

marketta,
Something else in the circuit is probably bad to make those fail in that way.
Likely bad MOSFETs but could be many other things. (Or more than one thing.)

Handy logo site Starfury!
I used to know a huge one but it went *poof* about 3 years ago.

Re: hp pavilion zd 8008ea no charge

Finally got some data sheets.
Printed logo in the sheets is similar but not exact.
Probably the same company,, not 100% confidence.

Showed another AP part with 4407 to show how much difference one letter can make in a PN.

Re: hp pavilion zd 8008ea no charge

Had another but PDF files larger than 195.3k won't upload here.

Re: hp pavilion zd 8008ea no charge

thanks to all for the answers and the suggestions
I have found a supplier in Italy
I now buy them him they are the AF4407

I was sure a bigger one existed too so that maybe the one I was thinking of but couldn't find. (haven't been logo hunting in awhile)

without knowing the exact pint out for circuit the photos you posted I think the "M" matches..pin out wise...they are in parallel ? pairs possibly

anyway for ref from PDF I found and the one Bonez posted.

the Anachip pdf snip

that if I got it all right here

keep us posted on how you go...hope it works too.

Re: hp pavilion zd 8008ea no charge

There is another one that is more complex, I think two transistors with seperate drives all in the SOIC 4 pin package.

Dell D600

Well, in my case FDS36B is blown in few cycles if I kept trying (power supply kept shutting off instant the I press power button. But with battery all you do is just once and it's blown. I could not find the short, lowest ohms I can get is about 30 ohm far downsteam and is on seperate choppers but not where this IC is which is with CPU installed and it is not shorted.

This IC that get killed is for the 2.5 mH inductor coil with 4 copper wires wround in a buck step-down voltage regulator.

Can a bad inductor kill a chopper instantly?

Re: hp pavilion zd 8008ea no charge

kindly someone knows What The Site is where I can find the manual service of the ZD8000

follow the gate lead to the driver chip.
it likely got killed in the original event.
its now locking on the new mosfet and killing it.

Re: hp pavilion zd 8008ea no charge

@ willawake
I thank you
but on your manual service doesn't exist electric scheme and any part list of the electronic components.
@ kc8adu
explained better before I replace the Mosfets 4407
thanks to all of my friends

i have never seen this for any laptop

[marketta]

Re: hp pavilion zd 8008ea no charge

however from some part it has to be this manual service
without doubt HP surely but it seems both top secret
thanks

[willawake]

Re: hp pavilion zd 8008ea no charge

which part?
show a pic

[marketta]

Re: hp pavilion zd 8008ea no charge

anybody part I want the electric scheme and the list parts that it is found on the manual service HP
