Flashing CAPS lock , wont boot , memory issue

Dell Inspiron 1501, vista basic, pc-2 5300

 

Hi, someone gave me their laptop to look at as it was slow.One of the first things I noticed was excessive paging. I had some memory same type and speed from another dell which I attempted to put into the spare dimm b slot but when i did this the computer would not boot with flashing caps lock. This was a one gig stick to supplement the existing 1 gig stick.

To see if it was the memory I tried the existing memory stick in the spare slot on its own and got the same behavour so I concluded that it was a defective slot. Then put the spare memory in dimm a and it booted fine. So Spare memory fine.

So I then  tried a 2gig stick from a spare Latitude e6400 pc2-6400 in the good dimm A slot as I had read that this would work fine be it at  lower speed and it did, it booted up and performance was much better. However after rebooting the machine it would not POST and was beeping (not sure beeps, 1,4,3 I think?). I reinserted the memory and got the flashing caps lock light and no boot. Now the sames happens with the original memory in either slot.

I have removed all memory hd dvd and now even the motherboard battery but the same happens. I tried powering on with no memory and re-inserting as suggested elsewhere but no luck. Please help! What can I try?

Hi bilbodell,

I would suggest you to run MpMemory test on the computer.

  1. Boot the system to the utility partition by tapping F12 at dell logo and select Diagnostics.
  2. From the One time boot menu select Diagnostics and Press Enter.
  3. It runs a test on all the hardware components.
  4. If it test fails please capture the error code and let me know the error code, I would tell you the next course of action. In case the test passes, follow the next steps.
  5. From the options menu, select Test Memory.
  6. If MpMemory fails, follow these steps:
  • Replace the specific memory module indicated.
  • If no specific memory module is indicated, troubleshoot by other means including swapping or removing memory modules.

If MpMemory passes, follow these steps:

  • Determine if the problem is intermittent, as intermittent problems can be difficult to catch.
  • If these tests pass or memory is not suspected as an issue, then select Test System from the option menu to run Dell Diagnostics to determine what else might be causing the problem. All tests are generally recommended.

Please post the results.

Thanks & Regards,

Re: Flashing CAPS lock , wont boot , memory issue

Thanks for the reply but the machine screen stays black and I no longer get a dell logo, the caps lock just flashes very fast.

I have tried different known good memory from another system and the same thing continues. Ho can I get to the diagnostics screen if I cant get past the logo?

Hi bilbodell,

Flashing Caps Lock light indicates that the memory is believed to be good but it is about to be exercised (such as when shadowing the BIOS and when testing / zeroing all memory). It could also indicate that the system is not accepting the memory module.

Please try a different memory stick, also check the memory stick you are trying to insert meets the technical specifications for the memory module supported by Inspiron 1501 as shown in the below table:

 Please check and reply for any further help.

Thanks for the suggestion. The original memory which was working fine will not work, infact none of the spare memory I have will.

Putting Latitude e6400 pc2-6400 ddr2 memory in should not have damaged it should it?

Hi bilbodell,

I appreciate your effort of performing the troubleshooting steps; based on the results this could be a problem with the memory card slot on the motherboard of the system, as even after changing multiple memory cards the system is not responding.

If there is a possibility, try swapping the motherboard at a local tech store and check the functionality of the computer and reply.

Hi bilbodell,

Yes, ouw953 is the right motherboard part number for Inspiron 1501; you can also check this part # JN596.

I have replaced the mainboard and it is doing the same thing! What the heck could it be? Could it be the processor??
