Vostro 3550 automatically restarts (loop) each 3 seconds
*** Dell Support,
I've got an issue with a Vostro 3550 laptop.
When I turn the laptop on, it just doesn't boot up at all but it automatically resarts every 3 seconds meanwhile the screen is black. The power button, fan, 3 side buttons and also the front power indicator flash during this period. Its happens the same when it is on battery and when the power cable is connected.
I did the following tests meanwhile:
1. Remove the battery and power cable and press the power button for 1 min and try to switch on.
2. Remove the cmos battery for 10 min and do the procedure #1
3. Remove RAM memories one by one and do the procedure #1.
4. Measure the voltage at the connector of power adapter (it was 19.3v)
5. Measure voltage at the power circuit inside the laptop for any possible problem with laptop on board power connector and it was ok.
6. I checked for any disconnected ribbon or cable but everything was fine.
Anyone got any ideas what the issue is or what I'm doing wrong?
Thanks
Eris

Hi Eris,
Thanks for writing to us
When did the issue start?
Would it be possible for you to try a different hard drive or this hard drive on another machine?
How about diagnostics? Please run diagnostics from f12 (should it allow) menu and let us know.

Hello Hema,
I have good news. I reached to switch it on today for few minutes and i got the blue screen with window error: memory_management.
Then i read about this error and i understood that it was an error related with RAM.
I removed once again both RAM-s. I have one 4gb and one 2gb.
Later i tried placing again inside the slot. I placed first only RAM 4gb and tried to switch on, but was the same thing, same problem.
Then i placed only RAM 2gb and suddenly it worked . The laptop continued the startup normally.
So the problem was one of the RAM memories.
Now im using the system with only 2gb RAM but i need to buy another one soon coz this is two small for this laptop.
However thank you for the fast reply and support.
Have a great time.
Eris.
