[Notebooks] Schematic for HP DV9009cl in Road Warriors, Notebooks & Distance http://www.dslreports.com/forum/r21121943 en Tue, 15 Dec 2009 03:36:49 EDT Tue, 15 Dec 2009 03:36:49 EDT Re: [Notebooks] Schematic for HP DV9009cl http://www.dslreports.com/forum/remark,21189337 privatepilot : Here is the return info on the laptop repaired by HP. This is REALLY good service.

It does appear to be the same case I returned. The enclosed letter has checks by "Repaired (The problem was duplicated during full diagnostics)" and by "System Board".

No bills.. NADA..

I now have a 90 day warranty with a fine working laptop! PP

The above URL points to a 'limited warranty service enhancement'. After a phone call to the number within and a number of 'checks' over the phone, Sara agreed to send me a box to return the HP dv9009 for a FREE repair. [it is well beyond the standard warranty]

Hmmm, I may have two HP laptops that work... PP

edit: FedEx picked it up today [8/23/08] prepaid box!]]> http://www.dslreports.com/forum/remark,21143023 Sat, 20 Sep 2008 19:49:16 EDT Re: [Notebooks] Schematic for HP DV9009cl http://www.dslreports.com/forum/remark,21142622 PeteC2 :

I found a very similar HP DV9000 series in the local paper classifieds and now am the proud owner of it for less money than HP wanted for a replacement mb. I just plugged in my HD and off we went. Now I have a bunch of spare parts providing the mb on my 'new' HP will not poop out too... PP
Not a bad remedy at all! I do understand your preference for specific "on-point" repairs versus the "yank the whole board out and replace it" paradigm...I really do. I am of that certain age range where "repair" is a more respected word than "replace".

However, I do also understand that given the actual low cost of main-boards (at the manufacturer's end), and the high cost of skilled labor...the "chuck it and replace it" scheme does make economic sense.

1st to Vintagewino. I too have been involved in electronics for over 40 years and seen the situation you described. IHMO, the driving force was mgt not wanting to invest in skilled labor and wanting to 'cross train' everyone... replacing a 'board' was easy. If you had five slots, you had five boards and replace in turn until the problem went away. If not, plug a phone in your ear and have a manuf 'tech' talk you through a supposed fix. Perhaps that way is better..but I digress. [I no NOT agree]

With most everything being surface-mount, trying to unsolder anything becomes a real challenge.

Having been involved in electronics for over 40 years, I have noticed that getting actual schematics has gotten worse and worse over the last 15 years. Troubleshoot to board/module level, replace the board/module. No real choice anymore. Heck, on the equipment I work on, the OEM's will at most give you a simplified logic flow only, if you're lucky. And that equipment starts at $50k (that is NOT a typo) and climbs rapidly from there.

Check at the power supply connector on the end of the cable that is going to the computer with a voltmeter to see if power is available to the machine. Should be somewhere in the range of 14-17 volts, or 17-21 volts. The plug on the thin, flexible cable is a stress point to break fairly easily. (Green light on the power pack, but nothing to the machine.

Other than that, you'll be in for quite a few $$$ for a power inverter board or mainboard.

Good luck.]]> http://www.dslreports.com/forum/remark,21140251 Sat, 20 Sep 2008 00:33:56 EDT Re: [Notebooks] Schematic for HP DV9009cl http://www.dslreports.com/forum/remark,21135408 privatepilot : For flyingroach,
Thanks for the heads up. Unfortunately, NONE of my light are lit except the one around the power plug.

I'll place a call anyway and see what happens..

With a background of building computers for process control using wire wraps and when a 4K memory module consisted of 'donut' holes and sense wires, it is difficult to give up a complete mother board for a minor problem...
I hear you...but unfortunately even repair shops or HP's own repair facility do not do repairs at that level. At current labor rates, etc., the common fix is to simply replace the entire part, such as the motherboard...it is almost unheard of to have motherboards repaired...just not considered cost effective on today's designs. That's why schematics are seldom published, and even if so, are hard to find.

[I also have two other HP laptops and have their manuals also]

I also agree that it is not the power connector on this unit but the power jack was problematic on the other two. The 9009 has a good battery which probably confirms this.

We know the motherboard contains the power supply but the PS is just a small portion and would be easy to repair with a good schematic.. and for a lot less money.

I had hoped that someone browsing this forum would have access to one and be willing to share the power supply section.

Yep, that is what I was referring to! HP does a pretty good job making these very available, not all notebook manufacturers do...

Based on your symptoms, the most likely suspect is either a break at the AC in jack, or a failed motherboard. Usually, if it is the AC jack, some careful wiggling/manipulation of the jack will tend to show that this is the issue.

It is very easy for HP owners to download the service manual right at HP's support web site. No schematics, but very thorough step-by-step disassembly instructions.

If it is the AC jack, and it is not broken/cracked at the motherboard, then it can be pretty reasonably be fixed. If it is not that, then the motherboard will almost certainly need to be replaced.

I hate to say it, but as you characterized this as a "sudden death", I am not really suspecting the AC jack, more likely the motherboard.

I have experience [past life] fixing electronics but only when provided with a good schematic.

HP only wants to install a new PS for over 1/2 the price of a new laptop. It is out of warranty.

Our local computer repair shops only laugh at this question..but they didn't come from the 'old school'.
