: the symptom set you describe (internal keyboard, touchpad and USB ports dead after a Windows change) points more to a firmware/embedded-controller or hardware connection problem than to a normal Windows driver issue. As hinted, there are plausible hardware/firmware causes here, and the quickest path is a short, ordered checklist to rule them in or out.

  1. Perform an EC/power reset. Shut the laptop down, unplug the AC adapter, remove the main battery, then press and hold the power button for 20–30 seconds. Reconnect only AC and try powering on. This often clears embedded-controller lockups that disable input devices.
  2. Reset CMOS/BIOS defaults. If the EC reset did nothing, a CMOS reset (remove the internal coin cell for a few minutes or use the board reset method) will restore BIOS defaults. This can re-enable onboard ports disabled by firmware. If uncomfortable with internal disassembly, skip to step 5.
  3. Reseat the keyboard ribbon and related connectors. Laptops commonly lose keyboard/touchpad function when a ribbon is loose or corroded. Reseating the ZIF connector (gentle, careful work) is a low-cost fix.
  4. Boot from an external optical rescue image (Live CD/DVD) to confirm whether inputs respond in a pre-Windows environment. If the keyboard works there but not in Windows, the problem is software/driver-related; if it does not, the fault is firmware/hardware.
  5. If none of the above helps, do not attempt extensive repairs if the machine is under warranty. Contact Acer service or a qualified repair shop. Replacement of the keyboard or mainboard connector is a common outcome.
  6. If the device works in BIOS but not in Windows, download the TravelMate chipset/input drivers and BIOS update from Acer on another PC onto media, then install them on the laptop.

Start with the EC reset and the Live-CD check. Those two steps narrow the problem quickly and safely.

Member Avatar for caperjack

yeah that is a surprise ,after you install win7 did it boot up and work

Member Avatar for futgates

its booting up very well but all the usb ports,mouse,in built keyboard are not working..thats why am confused and stressed out

Member Avatar for caperjack

that make no sense to me ,why all those devices would not work ,,so i assume it will not boot directly to the win7 dvd so you can try reinstalling win7 ,and i really don't have much to add, sorry
