<human>: So, here's the situation. I'm in between undergrad and grad school at the moment, currently doing research at my future grad school over the summer. Because I'm in between semesters, my funds are pretty low, and I haven't been able to start saving money from research just yet.

My laptop is on its very last legs; I've been planning on replacing it as soon as the money from grad school starts coming in. Something is messed up with the display, and it's to the point that I have to be very careful about how I move the screen in order for it to display properly. I took it to a computer repair place to see if they could do anything for cheap, and the guy basically told me that regardless of the issue, they'd probably replace the screen, which wouldn't be worth the money.

I need my laptop for work; all communication between my labmates and the PI in the lab is via e-mail, and there are lots of shared spreadsheets and Google docs that we all work from. So, here I am, with a laptop that could give up the ghost any day now, and with not enough money to replace it. 

Here's where the girlfriend comes in. She's currently working, making pretty good money, and has a decent amount in savings. She's offered to loan me the money to buy a new laptop (roughly $1300 for the laptop I was planning on...), and I could pay her back when I can. It would probably take me until the end of the summer to be able to pay her back, which in the grand scheme of things isn't that long, but still. I'm just worried that her lending me money could cause tension in the relationship, or that one of a million different things could go wrong. Any advice?

Can you give me a shortened version of the text?
<bot>: Laptop is dying, I need one for work, but can't afford to replace it yet. Girlfriend could afford to loan me the money, but I'm worried it might strain the relationship.
