NP4750/Clevo D470K southbridge bad contact issue

post #1 of 3
Thread Starter 
Hello all,

I bought my NP4750 through PowerNotebooks.com (here in Canada, Eurocom was carrying it for 500$CDN more that I didn't want to pay as a broke student) in october 2004 as my first laptop with the intention of going mobile while getting a serious computing power upgrade from my aging 500MHz (first computer ), even maxed out at 320MB RAM and a total of 310GB storage.

I received it after 4 weeks (b/c I ordered a special keyboard they didn't have in stock) with a crack in the case just under the arrow keys, and, fortunately, after opening it I found that a speaker wire wasn't in its place and pushed the case when it was fastened, causing the crack. Nevertheless I was still happy with it, and it performed flawlessly until 18th december 2005, after this date it all of a sudden refused to get beyond POST, and I got the following errors: (copy pasted from the text file I sent to Sager)
- SOMETIMES optical drive wasn't detected
- When detected, it was not always possible to boot from a CD in it

- ALMOST ALWAYS hard drive model number wasn't detected correctly
- Hard drive does spinned OK in the laptop computer and worked fine
in desktop PC.

- OFTEN the POST test output the following line:
"PCI Parity Error on Bus/Device/Function at 0030h"
More of the same line always shown: 0040h, 0070h, 0071h
These adresses were sometime displayed IN ADDITION: 0000h, 0028h, 0060h

From the above I deduce that there must be a bad contact (fissured solder/whatever) somewhere around the southbridge, which doesn't seem a big issue as is.

However after more than 2 months trying to send it back to Sager for repair (FedEx failed 3 TIMES at it, and finally decided to refund me, then UPS first got problems with the f****** paranoid US customs, and second, said they didn't find Sager facility adress (!), but it finally got there), I received a mail from the tech support: the case has numerous small cracks, but it's not that expensive (about 50$US for the total), but the point is he told me that the whole motherboard was to change, for a whopping 455$US ! (The whole repair topping at 610$US) Previoulsy, I told my boss (which helped me get the taxes refunded on the machine) the issue, and he called PowerNotebooks to try getting a "commercially acceptable" solution to get a price on the repair, which he got (however with no precise value yet), but apparently, it hasn't been transmitted from PowerNotebooks to Sager Tech department !

Is there any place where I could get a NP4750 motherboard at a reasonnable price ? Or just getting the problem fixed without changing the whole bunch ? Or is Sager telling me the price they get it from Clevo, or so ? That's because, I didn't got rich in between, and more than 25% of the price I paid it back in 2004 seems too much for me, especially after just more than a year. And I don't take into account the 1 month (at best) downtime.

Of course, I hadn't asked for an extended warranty when I bought it, as I was told that, when vendors put a 3 years warranty on a product, that's because they know it won't fail in this period.

This issue doesn't makes me happy, as I see many people lovingly running their PowerBook with decent power AND battery life, still not having a single major issue with it in more than 3 years...

Sorry to hear things are not going well with your unit.

I agree that a mainboard replacement may be a more cost effective solution than trying to find and repair a defect on it. The model has been discontinued and parts will dry up soon afterwards depending on the model's popularity. Nevertheless, yes, the part appears to be that expensive as many have reported before.

In the end, sending it back to Sager at cost is the only viable option I see.

And yes, regardless of what some say, 3+ year warranties are mandatory regardless of manufacturer or model.

Parity errors

I had the same problem 2 months ago with my 4790. Started getting POST screen interrupt errors, and if I could get past those, Windows would BSOD with Parity errors.

So, being fortunate to have bought 3 year warranty, I sent the unit to DiscountLaptops where I bought the unit from. After 45 days of me pretty much nagging and begging them to fix it, they change a memory stick and send it back. Guess what? I boot up the machine, and the same damn error is still there. Talk about incompetence (the service company is ATS Warranty, BTW). So this time I manage to convince them to send it to Sager. It's been a week there, we'll see how it goes. Very grueling experience so far... really makes me think twice before buying another Sager machine (just for the lack of support).
