worried about the laptop

I've been using my sister's (Charisse) laptop eversince I'm into blogging cause our PC is already obsolete and we don't have yet our internet connection. Buti nalang, she's taking up IT and my brother (Joel) gave this laptop to her. Yesterday, i used it for 5hours and left the house to attend our dance practice. This morning, my son told me that the laptop is totally black out and i get worried thinking i won't be able to replace a new one. When i went to my sister's house, i saw her using her laptop, thank's God, it's running again!

I plan and hope I would be able to buy one before this year ends.
