Hi,
I have a Dell Latitude 3540 which worked fine untill previous day night and i have shut down it normally. But next day morning when i tried to turn on only the power LED is on, and there is no processor fan running or other led's blinking. The power LED just blinks white with an approximate 5 second interval, it doesnt even turnoff if i press and hold power button. The power LED blinks like when it is sleep mode but with a long "ON" time
Steps i tried.
1.)removed battery for 30 minutes, pressed and hold power button for 1 minute while battery removed.
2.) re-inserted battery and tested. same result
3.) removed battery and tested with only power adapter. again same result, only power led blinks.
4.) Removed one RAM out of 2 and tested, inserted ram in alternate slot.....
Nothing Worked.
The laptop motherboard was previously damaged within 2 months of purchase and it was replaced under warranty. and after 4 months from then laptop became very slow and after few days HDD was damaged which was again replaced. and again within 2 months i got this issue... i think i got a defective laptop while purchase.
