About a month ago my HP Pavillion dv2700 Notebook started acting up after a windows update (windows 7)
Here are the symptoms:

- Can only start up off of battery, if AC has been plugged in before start-up and i power it on it beeps loudly (1 long 2 short) continuously and the screen stays black. (I can plug it in after it boots up though)

- Windows stopped loading (Hangs at "starting windows") so i used my Ubuntu disk to wipe the hard drive and install Ubuntu.

- Fan runs at full speed

- Touchpad works but doesn't lock, lock light/button blinks in synchronization with battery light (orange then blue)

- Keyboard FN(function) keys don't work at all (if they have a function, they don't work at all)
so i plugged in an external usb keyboard to install ubuntu and use my laptop.

Ubuntu runs perfectly but the hardware is still acting strange

when i try to install Windows 7 again it hangs at "Starting windows" i run it in safety and it freezes at "DRIVERS\disk.sys"

Any suggestions?
Thanks! -Nick

update and flash your bios, might solve your problems.

I tried :[ But im on Linux i tried booting "FreeDOS" and running "phlash16.exe" (i know i left out a lot but you should know what that is) and i have the latest bios version but it gave me the error "Cannot flash when memory manager (e.g. EMM386) is present" (or something along those lines)

Hey men, It's so later but I have the same problem in Colombia and I don't trust in Colombian computer technicians. Do you have any idea the cause of the problem? or How do you solve it?

Thanks so much
