Inspiron 640M Does Not Boot
Hi,
I have a Dell Inspiron 640M /E1405 laptop. Its about 2 years old now.
The laptop does not boot after the power button is pressed. The power light turns on for 5 seconds and then turns off. No other LED turns on and there is no sound of the hard disk or the fan starting.
I have tried charging the battery, removing it and re-inserting it - but no help.
The laptop has not been updgraded and has the same configuration as shipped.
Could someone suggest what could be done to revive the laptop?
Thanks
Mayank

Try without the battery - if it'll power up, replace the battery. Verify that the LED on the AC adapter is ON - if it's not, replace it.
Failing that, it's the mainboard. They're not cheap to replace --

but Dell board prices are a fraction of what others charge - HP, $800+; Apple, $1,100+, etc.

Hi
Thanks for some tips. I tried the above instructions. Nothing seems to work. The only LED that glows is the power one for ~ 5 sec and then goes off. The only other LED that bothers to glow is the battery charge indicator.
I spoke to DELL and they have given me a astronomical quotation to replace the motherboard. The cost is outragreous and more than half of the cost of the notebook!!
Any suggestions / alternate ways to get the laptop repaired?
Regards
Mayank

Is it normal for a mainboard to go bad in 2 years.
What could be the reasons that its gone bad? What can I do to ensure it doesnt happen again?
Is this common or a problem with select models / notebooks?

About 20% of all notebooks will have a major hardware failure such as a board in the first three years; you're just one of the one in five. About 3/4 of all notebooks come from just two companies - the remaining 25% from another 4-5 manufacturers - they're more alike than different.
Any portable device is prone to failure from handling as well - desktop computers are generally more reliable.
