Android tablet doesn't power on

Hi guys,
Recently I bought an android tablet at Malaysia and it was fairly good to use.
Today I rooted the device and did a swap partition on the sd card. After this I reboot it but nothing happens.
I tried volume up key and power button for recovery but nothing works. It is not responding to anything. Even it is not charging when I plug it into the power. Please anyone help me to get my tablet back to life.

Model - A751
Manufacturer - unknown ( CellTech - Made in Taiwan - printed on back)
Android Version - 4.0.4
Baseband Version - A751_P2_10WX_AC01_SS_130326
Kernel Version - 3.0.8-perf-g9d5151f
Build Number - A751_P2_10WX_AC01_SS44_R_0_130326_01

Thanks.
 
does it do anything at all? (light up the screen, display the little android icon in the middle, etc?) i have a cheap Trio Tab that did that right out of the box, basically got a buggy bootloader that tends to freeze when powered on, and all it took was a few reboots with holding down power and it eventually takes. still has that issue from time to time i think it has something to do with the boot.img somewhere. when it is on and in standby it works quite well for a cheap tab.

if there is a tiny pinhole labeled 'reset' i'd stick a paperclip in there and hold it in until you see signs of life.

also must caution you, if this is a cheap tablet and if it runs ICS, running the battery flat on one can soft brick one, and it can take hours before you see it charge again. i think the Nexus 7 also has that bug if you let it die. (flying pixels of death i think it's called)
 
I'm curious as to what you used to root and repartition. Those files are device specific and you don't even know your device manufacturer. I once managed to soft brick my phone because I flashed the wrong CFroot, and thats with a known model. I mistakenly flashed the CFroot for a Euro version and I have an Asian version. If you tried to repartition it with files intended for another device, it may have broken your device.
 
I successfully rooted my device using unlockroot app. It was very nice experience and it worked well. I used the terminal emulator with su commands.
Then I tried to increase my ram capacity using swapper2 app. I partitioned the sd card using minitool through the usb cable and after doing the swap it directed to reboot the device and then the screen was light up. Thats all.
Then I managed to turn it off by long pressing the power button.
Then I tried to power on the device but it did nothing except vibrating twice.
After that I googled the issue and tried to boot it into recovery mode by using volume up power combinations several times. The result was nothing even it did not vibrate as before. I felt that it is dead now.
Is there any ways to wake it up???
I bought this tablet during my Malaysian visit for $170.00 and I feel it is not that cheep comparing to $70 tabs.

Pls help me.

I am afraid whether all system files are stored in the internal sd card??? Cos I formatted the sd card before partitioning it. Any how I can see some system image files and other stuffs related to my tab in sdk folder in my laptop.
Can I do something to wake my tab up?????

Another information is that one of my friend also bought the same model and have it right now. It is working perfectly. So do I have any means of recovering my tab using this??
