CPU DEAD!? Need advice On Upgrade CPU...

grokman645 · Apr 8, 2013

I bought (Wish I hadn't) an HP G71-442nr (WA609UA#ABA) Laptop with a dead (no Power at all) MB ... Thought it might be a simple fix (it wasn't) ... tried to oven bake MB back to life (ala YouTube) ... Didn't work, still DEAD ... bought cheap MB on eBay ... installed, now have full power (lights, fan, etc.) but no post, NO BEEPS, WHITE SCREEN ONLY ... Suspect I "murdered CPU" in failed baking effort ... My question; what is the best CPU compatible with this MB and am I likely right in my diagnoses of fried CPU? Stock CPU was Intel "T" series 2.1Ghz, can I replace with "P" series? Also, eBay MB HP Part #578703-001 is missing Locking Bar for Keyboard ribbon cable ... is bar from old dead MB removeable & reusable on eBay MB ... if not, can I either glue KB ribbon in place or fabricate some sort of compression material/device to lay on top of ribbon to keep it in place? I now have approximately $175.00 invested in this POS ... would like to fix cheap, sell quick and make this a "bad memory" asap! Thanks in advance for ANY info/advice. Jim

Break it for parts. Dont waste any more money on it.

oven baking a motherboard is a bad idea..

Agree. Its a terrible idea to do it with a CPU mounted to it. Any respectable guide will have you remove the CPU, RAM, CMOS battery, etc prior to a bake.

Add a little salt, your going to have to eat the chip at this point. I wouldn't waste anymore money on this adventure, chalk it up as a $175 loss.

You're going to be well over $175 into this rig if you really want to get it up and running.

My personal recommendation is to either A) part it out or B) sell it for just the chassis and let someone else deal with the headache.

Those are the only 2 really viable options to recoup any costs.

In my experience, laptops are a very mixed bag and they're difficult to work on, the upgrade components typically cost as much or more than desktop parts, and the market is more limited on a refurbished laptop then it is on an upgraded desktop. Further, it's a lot easier to screw them up if something doesn't "fit" right when you put everything back into the chassis.

I would consider buying a chassis and building from scratch on a laptop, I would not try to open a headache and go through it thoroughly. For what it would cost you to go through it, you could essentially build something new with no headaches.

Agreed that laptops/mobiles are a MAJOR PITA to upgrade/refurb. Will NEVER buy a "no power" laptop again. Got lucky and "bought cheap ... sold steep" about 8 or 9 in a row w/mostly software/OS issues, broken screens, keyboard issues, cosmetics, chargers/batteries ... then, cursed w/3 in a row with MB and GPU issues (G71, DV6, and DV2700) ...
In short ... NO POSTEE >>> NO BUYEE! ;-) I just bought a guaranteed functioning CPU identical to the one I fried off eBay for $2.78 ... I figure, since I've already got the PITA G71 apart, it's worth $2.78 (free shipping) to see if I get lucky and the thing magically boots into Windows 7 ... If not, BOOM! Assembled chassis is headin' for eBay with FULL DISCLOSURE. Wish me luck. Thanks, Jim (Sure hope I bought the correct CPU? Intel Core 2 Duo T4300 ... 478 pins, Socket P, 2.1Ghz, 800mhz FSB, 45nm ?)

Good luck buddy...keep me posted...I am not sure if T and P series are compatible...I am pretty sure T series has some onboard graphics, not sure it P does or not...

FYI your oem version of windows may need to be repurchased.. unless your using the exact same model motherboard as your previous laptop. the same rule applies with any desktop system as well generally if you change the motherboard they require you to buy another oem windows copy.
