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"
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)
