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

Re: Inspiron 640M Does Not Boot

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

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.

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?

Re: Inspiron 640M Does Not Boot

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.
