HP Pavilion dm4-1065dx long time to get the power led on

[OscarAV]

Hello,

I just came here to see if someone has had the same problem I have, and if he or she solved It, to know how to do It.

I have made a quick search for my laptop but I have not seen anything similar.

I have an old laptop, an HP Pavilion dm4-1065dx which takes a lot of time to be ready to start if the laptop has been unplugged for a while. It has no battery. The battery failed long time ago. It needs to be plugged to work. But as I said, It can take a lot of time until the charging led gets on, and I can switch on the laptop. I am using an external monitor and an external keyboard too. I am using the original adapter, and I have checked that gives the proper voltage.

There are many many components and I don't know what to check. Maybe some people have had the same problem, and if they managed to fix It, I can do the same to fix It too.

Thank you very much for your attention.

Regards

Make a request for clean me bios while posting your existing copy of bios in "Bios Section"
This is the first step under such scenario.

Thanks a lot. I went to the BIOS section, and read the guides there, but just to be sure before I post anything there. I downloaded two files, a BIOS configuration utility, sp143621.exe, and a HP UEFI Support Environment, sp61101.exe.

When I run the configuration utility on the cmd,

It gives me an error, system not supported, unable to connect to HP WMI namespace:'root\HP'

Then, I tried to install HP UEFI Support Environment, but It asks me to do a partition, and before accepting, I want to ask.

I changed the original hard drive to an SSD one.

I believe that at some point I updated the BIOS. In any case, in System Information on Windows 7 64 bits, the BIOS information says

BIOS Version/Date Hewlett Packard F.27, 21/12/2011
SMBIOS Version 2.6

I don't know if I could post this right on the BIOS section, so just in case I post It here before.

Thank you very much.
