if you are trying to turn on the laptop with only battery power it may be a bad battery and you can turn it on by using your charger. Even if you don't have a hard drive it should still boot to your BIOS.
you could almost run high setting with that laptop though you may run across latency and heavy loading screens because of the slow Hard Drive. If you can opt for 7200 rpm or a SSD with less storage space It would be a wise decision.
I'm ordering an Lenovo edge E530 and wondering what would improve overall performance the most , adding 2GB of RAM or adding a 16GB Solid State Cache drive. I'm trying to keep it under $600 so I can't get both.
