DV1000 Motherboard repair

Hi,

I noticed in June of this year that you posted on Fixya with a problem on your DV1000 motherboard. You stated that you found a short on PD28, and were going to post your progress in repairing it. Were you successful in getting the motherboard running again?

I have a DV1000 motherboard that is also dead. I found a bad PQ154 that I replaced, and it is still dead so I'm investigating other issues. I just found from your post that PD28 might also be bad, and mine measures 9ohms in either direction, I'll look at replacing this part but I'm curious to know what solved your problem.

Thanks, Ivan

    My hp pavillion dv 1000 just went dead a friend and opened it up it began to run but sa soon we closed it up it went dead again we are sure its not the batteries or the charger we tested these

    A common problem on this motherboard is a failed PQ154, a SI4800B FET. I had this problem on mine (would not turn on, no LED's, nothing). I checked PQ154 and it was bad, but also, the driver for this FET, PU4, could also be bad. It's a MAXIM MAX1999. I bought both from Digikey and replacing them solved my problem. You should replace both PQ154 and PU4 at the same time.

Best place I've found to fix 3 dv1000's is the Compaq and HP Notebook Forum - Unofficial forum for the Compaq and HP Notebooks/Laptops and if you know how to read schematics then you can download one here.

You have to look for a bad connection on MB. You have a broken trace from openning and closing. You need micro-soldering iron to fix it.

HP Pavilion Laptop -- massive power problems?


hello chad
Seem to be circuit issue.
You can check charger with volt meter to check its working ok.

Drain all resistors of power by removing battery and charger and holding down power button for 10 seconds.

There is a power button board that can be bad.

I like to break things down by just powering the laptop with memory and keyboard, power button board only. this will require removing motherboard power button board so it will only be the parts to POST.
Minimal Post .
It can be an array of things from the systems casing shorting it out to other hardware.

Need working X5DA8 SuperMicro Motherboard


Looks like a good idea, except for one small factor;

In the FixYa T.O.S. it states there is no buying, or selling on FixYa,

http://www.fixya.com/terms

HOWEVER, there are plenty of other websites, where this is allowed.

If FixYa allowed selling, and buying of products in the product problem/solution area; there would be no room for problems, and their solutions.

(FixYa would be more like Craigslist, or Ebay. Not the world's largest product support website)

I want the replacement motherboard part number


The part number you posted on the FixYa site is correct for a replacement board. It is actually designed for the DV1300 series but will work iin many DV1000 series notebooks. If you get on E-Bay and put that part number in the search box, you will find many that are for sale and under 120 bucks. Good luck

No display


Hi,

If there is no display, more likely you have a faulty motherboard. You need to get it repaired or buy new one.


I would advise you to buy a new one as it would add life for atleast next 5 years to the computer. Repair is not a good option as there are very few people who know to get this job done and they would charge half the rate of the new motherboard. If you know the repair, that's good unless go for a new one.

Any further help, let me know.

Thanks for using "Fixya".

Do rate the solution as "Fixya" if 100% satisfied.

Laptop lid actuator switch is loose


This is common problem. To get to that you'll have to take everything apart including motherboard. It's part of the top case. You'll have to bend it up for it to work or completely disable it permanently.

I need to replace the motherboard for a Dell Inspiron 5160 Laptop because the AC adapter connector is damage due to wear and tear. I do not know the correct type of motherboard to order. Any suggestions?


Hi there.
Instead of replacing the motherboard you can have a new adapter soldered on to the motherboard providing there is no more further damage to it, doing this will save you a small fortune as laptop motherboards are expensive.
All you have to do is phone around reputable PC repair shops and ask them if they do repairs on the AC adapters, I'm sure you will find one that does.
If really do want a replacement motherboard please post back.

Good luck and thanks for using FixYa!!

EPoX EP-8K7A+ motherboard - memory problems


The first thing i would suggest it so make sure you have the latest Flash Bios installed on your motherboard.

Just for giggles you could try to reverse the dimms just to make sure one of them isnt bad.

Another thing to try is to take a qtip with alcohol, unplug the computer and attempt to clean the contacts that house the dimm. If it has been in use for years there may be dust buildup.
