\015\012======================================================
\015\012My friend Juan Carlos asked me to check his laptop.
\015\012Captioned laptop was checked/inspected by two technicians and no one get it to work.
\015\012======================================================
\015\012Fault Description.
\015\012
\015\012After 3 months of use. The wireless mini-card fails. No wireless connection can be made.
\015\012Randomly the laptop fails to boot up. Black screen and power led (blue lights) on.
\015\012Owner took out the battery module and reset the laptop according user manual instructions. He got it to work a couple of times until the laptop was un-responsive at all.
\015\012
\015\012======================================================
\015\012I goggle the Laptop model number and the fault description and plenty entries showed up. Faulty motherboard, short guarantee from HP, etc…
\015\012I found the service manual from this series and I decided to verify if the motherboard was really damaged.
\015\012Prior a full dismantling I reset the bios by disconnecting the CRT battery. I made an other test: the machine starts the boot sequence, read from DVD, later pass to hard drive, the hard drive led blinks a couple the times and that’s all. After a period of time the laptop shut downs itself and reboots again….black screen ….nothing……..
\015\012======================================================
\015\012I tear down the laptop (according service manual instructions), check all boards and I did not find any sign of damaged component or over-heating.
\015\012I took special care during the dismantling, I let the CRT battery in place (motherboard) but I disconnect every thing. Everybody must be aware that this particular mobo has a
\015\012small switch (identical to the power switch). Captioned switch can no be accessed from outside (you have to dismantle the computer in order to see it). I took a ball pen and press this switch for five seconds (twice). I assembled back the laptop and make a test in order to see if starts. The machine boots and the set up screen came up. “ Press F1 to continue… I press F1 and the start sequence complete….
\015\012===========================================================
\015\012I found that the power settings in Power Profile (HP Recommended) was 2% in critical battery (too low in my opinion)
\015\012Conclusion: the machine is working; the only thing that I could not get to work was the wireless min-card. I reload the drivers but probably the mini-card is faulty.
\015\012
\015\012I hope that this solution helps.

Pls first check thru connecting normal pc Monitor as output from notebook see if monitor displays image if it doesnt then , do following

u should try replacing RAM if the system is not booting at all just fan is running and some light are blinking , then RAM is most likely giving problem try re fitting RAM , if u dont know how to let me know i will give u a tutorial for that . try taking out the RAM chips and then re fitting them individually i mean if u have 2 chips of suppose 512 mb each try one of them at a time

first take out both RAM chips and then re fit both and see if it works, if it doesnt then

try each one of them at a time se if u find the faulty one if it doent help then try a thrid one borrow it from someone and try but ur laptop needs to be same generation one u can ask me about the RAM model support and then try if it helps

other wise let me know

i will see more deep in the problem but i think it will resolve ur problem

pls rate me fixya if i fixed ur job
regards
