Inspiron 1525 won't boot up (motherboard issue?)

post #1 of 12
Thread Starter 
Hello everyone,

I'm having a serious problem with my laptop right now and I'm fearing the worst: a bad motherboard, a problem which I have found to be pretty common with 1525 users through Google/forum searches. Hopefully someone out there can relate and has a remedy that will save me money/time/hassles with my laptop, which by the way has been out of warranty for about 6 months.

I purchased the 1525 last April (2008) direct from Dell. Here are the vital specs: Inspiron 1525, Intel Core 2 Duo T5550, 1.83GHz, 667Mhz, 2ML2 Cache. I've never really had any problem with it until yesterday morning. I woke up and pressed the power button after allowing the system to hibernate the night before. The power LED lights up in the bottom left and the touch-sensitive media buttons flash from side-to-side like normal. I hear the optical drive "click," the fan whirs for a few seconds, but there is no action on my screen whatsoever. Pitch black with no flashing or any indication of life. A few seconds later, the computer powers down suddenly. I was stunned, and tried countless times after that but got the same result every time.

Figuring it was a battery or A/C adapter issue, I removed the battery (which is in fine shape, by the way), and tried powering on through just the A/C adapter. Same thing, no luck. Then I tried just using the battery. No luck again. Frightened that something might be wrong with my hardware, I immediately went onto another laptop to search the internet for people who've had similar problems. I read that it could be any combination of the following: bad RAM, bad peripherals, or a bad motherboard. I come to the conclusion I'm having a pre-BIOS failure, where one or more of the checks the computer does before booting is resulting in failure.

So, I turned over the computer and reseated the RAM, including taking out one stick at a time, switching ports, and even using other modules. No luck there. I read that it could be a faulty connector with the monitor, but I couldn't find anything wrong with that in the front panel. I also read a suggestion to hold down the power button for 30 seconds with the battery out. Did that, no luck. Also heard it could be the CMOS battery dead, though I would think that would be unlikely after only 18 months? Still, I'm gonna have to basically disassemble my computer to change that thing.

If anyone out there could help or has any suggestions, please send them along. I must also note two weird coincidences. The fact that it occured the night of Daylight Savings ("falling back" an hour) and that I upgraded to Windows 7 a few weeks ago. I made sure my computer was compatible and that I installed the right version, but I can't help but think it isn't compatible with my motherboard/integrated graphics card? Maybe, maybe not.

Thanks in advance for the help!

other than tring to re-seat the CPU, I tend to agree it sounds like a mobo problem

Yeah, I did read somewhere that re-seating the CPU could be a possibility. Still, with little hardware experience I would be afraid that I'd ruin it somehow. I'm finding conflicting procedures to re-seat the CPU in the Inspiron 1525. Is there any good documentation out there on how to do this, how involved it will be and if there are any risks to it?

Exactly the same problema in Inspiron 1525

Happened yesterday with the same notebook.. the same problem.
To solve this problem, what do I?

Start with re-seating the memory
try one stick then the other in each DIMM slot

Does the battery charge still?

The only problem i encountered because i took out the RAM module and put it back, it won't boot, i had to swap the RAM module seat to get it to work, then set it back again.

There is a motherboard problem.To be more specific is a southbridge trouble. You should find a service to replace the southbridge chipset and it will come bach alive.

You can also give a try to do a bios reset[before bringing the machine to service]: if you don't have acces to the bios battery tear appart the machine and remove the bios battery, press the power button for 3-50 seconds and then try to power up the machine.If still no boot, go to service.

i have the <5 sec problem posted above, but i'm inclined to think it's not the processor (or the probly monitor too?) 'coz sometimes it'll start all the way up and work for (usually lately) less than half an hour before a "must shut down" window comes up. then it either shuts down or just dies.

 

i found a post that it might be overheating and to remove the heat sink and clean dust out. did it. din't help.

 

thnx in advance :/
