How to use HDMI/VGA ports on a laptop if OS only sees integrated graphics?

[Colorful Life]

Laptop: Dell Inspiron N5010

CPU: Intel® Core™ i3-350M Processor

Graphics: Intel HD Graphics + AMD ATI Mobility Radeon HD 5650/5470/4200/550v

Backstory:

The graphics on the laptop got bad, cant see whats on the display bad. HDMI port also stopped working. So my dad got the laptop repaired in a "shop".

Now Ubuntu recognizes the INTEL integrated graphics and works fine; Windows 7 just gives up and fails to load a proper driver-- uses lower resolution. I tried "driver update softwares" etc. but to no avail but no worry, I wiped Windows 7 and only Ubuntu is present on the laptop.

Now:

What I actually want is to hook up the laptop to my TV and watch videos. But neither HDMI or VGA ports seem to work.

lspci says it only sees the INTEL integrated graphics. No sign of AMD graphics card. (Did the repair guys remove it? I am interested to know if it's even possible!)

xrandr says there is a VGA port (yay!) but it is disconnected (edit: plugged it to a monitor).

There is no setting in the BIOS to enable or disable graphic cards. (Actually I am shocked how basic the BIOS is.)

Can I use HDMI/VGA ports when using integrated graphics?

I don't care which graphics card is used as along as I can hook it up to the TV.

If the AMD is bad/dead then it won't see it. I would check with the repair person and ask what they did 'exactly' when they worked on the device.
