Clevo W870CU/Sager NP8760

Since the official thread is now locked I posted here. Hopefully this is the correct place. I have this old laptop. It quit working several years ago, but I still have it. I thought it would be an interesting project to see if I could get it back up and running.

The motherboard is diagnosed as the problem. Turn it on. It immediately powers off.

I searched for motherboards. Part number 6-77-8700-D04. The thing is I keep getting results for the Clevo W870CU/Sager NP8760 with motherboards 6-77-8600-D03, 6-77-8600-D04, and 6-77-8600-D05. These motherboards are supposed to be for the Clevo W860CU/Sager NP8690 which is the 15" laptop.

I am trying to find out if Clevo used these motherboards in the W870CU. Is there a difference? Same board different part numbers depending on the model? Started with one then moved to two? Started with two then moved to one? Some W870CU has them depending on specs the rest have the 6-77-8700-D04?

The pictures look exactly the same in the Technical Manual. Unfortunately, I have no idea how to dicern the differences using the schematic diagrams as I do not see anything the specifies a difference between an W870CU board and a W860CU board. Any information would be helpful.

Thanks.

 

This is the response I received from Sager technical support.

"Thank you for the inquiry.
This model NP8760 has been discontinued and is no longer available long time ago.
We don't have such information about the motherboard Part number of the laptop."

I suppose it was what I was expecting to hear.

 

Honestly, you should try to sell it or keep the parts and purchase a newer laptop, that laptop is about 6-7 years old at this point

 

I have already replaced the laptop with the one I use currently. I do not feel there would be many offers for it. I just thought it would be a nice little project to play with. I guess, I need to start looking at the recycling bin. I would rather finish it though.

 

It's highly unlikely you'll find a compatible motherboard, and I doubt anyone can confirm that the ones you listed work besides you buy ordering them, and I do like tinkering things, don't get me wrong, but paying $300+ to fix a 7 year old laptop? Ehhhh

 

Well, I also sent Clevo technical support an e-mail. I am curious what that response will be. I guess I will wait for it before declaring all is lost.

 

I don't believe Clevo will respond to consumer emails... While not 100% certain, I believe they mostly like consumers to work with the ODM which sold them the machine.

 

Found something interesting and confusing all at the same time. Then again I have no idea if it makes any difference. I was looking at pictures of these motherboards. I found a picture of a 6-77-W8600-D03B, 6-77-W8600-D04, and 6-77-W8600-D05. So, the 6-77-W8600-D03B is listed as a Clevo W860CU/Sager NP8690 mobo. On the RAM modules there is a barcode and voltage listing. I can not make out what the voltage listing is but the barcode has W860 in it. The 6-77-W8600-D04 board is listed as a Clevo W870CU/Sager NP8760 mobo. The barcode on the RAM module has W870 listed with 4 volts. The technical manual shows both models with 4 volt mobos, but its the bar code with the W870 on it that has me interested. So, I decided to look up the mobo for the Clevo W880CU/Sager NP8850 which uses the same chassis with an taller back plate and a larger vga cooler. The mobo part number is listed as 6-77-8700-D05-3 which is a 5 volt mobo. I found a listing for an W880CU/Sager NP8850 mobo but the part number on it is 6-77-W8600-D05. However, the barcode on the RAM module lists W870 and 5 volts which makes it look correct for the W880CU/Sager NP8850 since its the only one that lists a 5 volt mobo in the technical manuals.

Of coarse, all of this may not matter as the part number is an 8600 p/n and not an 8700 p/n and they just increased the voltages and stuff as different CPU's and VGA cards became available and all these boards are for the Clevo W860CU/Sager NP8690 and the W860/W870 on the barcodes does not mean anything as far as which model the board belongs to. Interesting stuff anyway. I wish i could find a 6-77-W8600-D04 board listed for a Clevo W860CU/Sager NP8690 and see if the barcode has W860 listed with 4 volts. That would then atl east give some indication that the W860/W870 listed on the barcodes show what model they belong to.

 

My search for a motherboard is over. I finally decided to just pull the laptop apart and check the part # which was a 6-77-W8600-D05. I found one for fairly cheap and have ordered it. Now lets hope it actually works as stated.

I am wondering if anyone in the community may have a battery (6-87-W870S-421A) working or not they may be willing to sell. Any information where to find one would be helpful. I have, of coarse, emailed every vendor online that I could find. I am only trying to fill battery compartment.

Thanks.

 

I received the motherboard and it worked out fine. The laptop is back up and running. Just need to fill the void were the battery was to keep it from wabbling. Someone also mentioned a larger power brick. I may look into that also.

 

Vathraq, I think you and I are the last two people with NP8760s... mine died last year and I was trying to revive it the last couple days. I attempted testing many capacitors on the board but I got nowhere doing so.

I'd like to use mine as a media center for our TV. It was a powerful computer in its day. I'm sure it would be perfect for it.

I'd like talk to you about what you did to fix it. I couldn't figure out how to privately message people on here. But we can talk on this thread, or you can email me. Hope to hear back from ya!
