Accidentally I put a 32V charger on my laptop with a Hannstar J MV-4 moyherboard. Did I kill the thing?

Oh I guess.


(lol!)





By the way.......what the h3ll is a, "loading diode of the right 19V laptop charger"?

HP Pavilion dv2000 series of Notebook PC motherboard?

http://www.ebay.com/itm/440769-001-HP-Pavilion-dv2000-dv2100-Series-De-Featured-DF-Laptop-Motherboard-/261162272180?pt=Motherboards&hash=item3cce7c05b4

Is $35 USD too much to repair your laptop?

Not advertising for seller nor website. Just from a quick search.

Suggest you cut out the middle man, (Reseller), and replace it yourself. Keep your hard earned money in your pocket, and stop listening to the prattle of that reseller.

One thing to bear in mind when it comes to the HP Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series;

the cooling for the graphics chipset is INADEQUATE.

This is also a good time to fix that problem.

More on that later in solution.

HOWEVER, when purchasing suggest you contact seller, and ask what the return policy is if motherboard is no good.
Tell seller you are using an ESD wrist strap, and following Anti-Static Precautions; and this ain't your 'first barbecue'.

Which you better be. Wearing an ESD wrist strap, and have it's alligator clip attached to a good ground source.

Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Wearing an ESD wrist strap, and having the alligator clip attached to a good ground source, ensures your laptop is safe from Static. (From you)

Average cost is $3 to $6. Here is an example,

http://www.radioshack.com/product/index.jsp?productId=2103245

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
I feel an Anti-Static Mat is unwarranted, and can explain in detail.

You can set a large metal serving tray (Unpainted), on the table you're working on; and connect to it.
You can also use a large metal knickknack (Unpainted)

Use a multi-compartment container, for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise do NOT mix them up.

Make a personal record as you disassemble. Make notes and drawings if needed. Take photos, or use a video cam. (Use good lighting)
It's nice to have a Service Manual, but even nicer to have your OWN personal information too.

Service Manual,

The Illustrated Parts Catalog starts on Page 65.
There is an exploded diagram of the computer's major components, on Page 66,
3.2 Computer Major Components

Page 183 - System Board, deals with replacing the motherboard.

The components are listed in an order of removal.
Let's use the first one as an example;
Hard Drive (Section 5.4)

Click on the blue Section 5.4
Takes you to removal of the Harddrive. Now you want to go back to the page where you were, so you can remove the next component in the order of disassembly.

Adding copper sheeting for repair on inadequate cooling problem,

Reflowing is not necessary. Just add surface area.

Board level component repair.
You'd be replacing Power MOSFET's. Maybe a Diode, or two also.
(SMD/SMT diode)

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

The above is for the HP Pavilion dv6000, and Pavilion dv9000 series of Notebook PC's.
Can be crossed over to the Pavilion dv2000 series, also.

The Power MOSFET's will be close to where the DC Power Jack is, on the motherboard.
(The DC Power Jack is where the AC adapter {Charger} plugs in)

Using the above example, and the Power MOSFET's used on it;

Fairchild Semiconductor Industries - FDS6679 - Power MOSFET,
and,
Alpha & Omega Semiconductor Ltd - AO4407 - Power MOSFET;

,let's look at availability, and price,

http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679

Scroll down a little. Here we see the FDS6679 is obsolete.
Let's use the cross replacement FDS6679AZ,

AO4407,

http://www.mouser.com/Search/Refine.aspx?Keyword=AO4407

Here we see it is obsolete too.
Using cross reference DMP3020LSS-13 for an example,

Short answer?

NO, I do not agree with reseller, lol!

Granted not everyone wants to attempt board level component repair, but replacing a motherboard isn't that difficult. I have taught two
9 year old children to do it.

So................$35 USD to $70 USD for a replacement motherboard, is going to = a new laptop?

$229 motherboard isn't going to = a new laptop.
