Laptop not booting + no wifi

[techking_dinesh]

Hello,

My laptop : HP pavillion tx1003au tablet
Warranty : Over
Already purchased : New battery and new adapter ( charger )
Already Done : 3 Full format
1. Vista itself
2. windows 7
3. Windows xp

everything is fine in device manager

Problem:

1. On turning the laptop on , only the lights come up , i dnt even get the hp logo many a times , i can hear d fan and processor.. nothing happens till battery dies.. Sometimes if u r lucky the laptop boots and works fine

2. The laptop does not detect any WIFI CARD DEVICE ( as if dere is no wlan in my lappy )
I tried everything at my level , here is wat i got in d end , my lappy wlan card works in my friend`s lappy but my friends`s card does not work in mine and hence i concluded dat dere is no problem with the wlan card

RAM, Hardisk is fine >> did all diagonistic test for problem 1
battery and charger are new

What can the problem be ??

If motherboard , what is to be done ? its a lappy ?? i dnt wanna shell out much money

Need to get this sorted asap


Regards

There might be too many complexities. Get it RMA'd.

probably loose connection in mobo. Send it for rma.
