Laptop Tech,

I have a 6735s and it just wont boot, that is it did until i removed the battery, the reason i removed the battery was the bios was reporting at top left hand corner “invalid serial number.” and i thought that there might be a possibility that the battery might not be genuine hp, so in removing the battery after powering off and re-inserting it i notice the power jack light is solid white (well i think its white) with a fashing orange light with 1 second intervals, i take it that the motherboard has had a short?

Have you seen this before?

GordonB,

Upgrading the HD. I’m planning on installing a fresh Win7 h.p. on the 6735, so as a back out I want to get say a 250gb HD to build on. Are there any issues I need to be aware of?

There shouldn’t be any problem. The new hard drive should be detected by the laptop and operating system automatically.

Are the standard drivers in Win7 up to running this Laptop or do I have to overlay the HP ones…

You install Windows 7 first and after that look in the device manager. Download and install all missing drivers from HP website.

This machine is still having overheating issues even when the BIOS has been set to keep the fan on when on mains.

Have you tried cleaning the cooling module? Maybe the heat sink is clogged with dust and the laptop overheats because of that.

Hi there… 3 questions:
1. Upgrading the HD. I’m planning on installing a fresh Win7 h.p. on the 6735, so as a back out I want to get say a 250gb HD to build on. Are there any issues I need to be aware of?
2. Are the standard drivers in Win7 up to running this Laptop or do I have to overlay the HP ones…
3. This machine is still having overheating issues even when the BIOS has been set to keep the fan on when on mains. Is a BIOS upgrade going to help sort this out.

The machine is just out of warrenty ;-(

Thanks in advance.

nela,

To cut it short, I just wanted to know, is that normal for a motherboard to die for 1 year???

It’s not normal but possible. I’ve seen many laptops like that.

And does it really cost that much 300 euro?

I think you can find it cheaper if buy yourself. The service center has to increase the price in order to cover shipping expenses, research time, warranty, time involved, etc…

Most likely the replacement motherboard will not be brand new and come with a very short warranty period (probably 30 days). Instead of replacing the motherboard, I would use the money for a new laptop.

Hello. I need some advice. My hp compaq 6735s laptop does not switch on. I press the on button and it turns blue and then goes again. I sent it to the IT guys of the shop where I bought the notebook and they told me there is a problem with the board, and it costs around 300 Euro to replace it. The problem is my guarantee expired in December, and I have only used the laptop for 1 year. I’ve had problems with it since the very first months. To cut it short, I just wanted to know, is that normal for a motherboard to die for 1 year??? And does it really cost that much 300 euro? (I bought the new laptop for 370 euro).
I would really appreciate your help.. thnxxxx.

Dear Laptop Teach.
First off compliments for this “How to”. I found this, while I was writing something on my Blog about my experience with this Laptop. The problem of “overheats” comes by the fact that there isn’t a door for the cooling fan, as you said, and that there are 2 stickers (you can see them on the penultimate picture ) that block the 2 cracks in the back. I’m so sorry, because this is a good laptop and cheap at the same time, but I will never understand the absence of the cooling door and the presence of those stickers. My solution was to do some holes close to the fan. I know this isn’t a solution but this is mine solution, I did this only because my guarantee was over.. I was lucky.. Best regards and compliments again !!!

P:S Sorry for my English
