my laptop’s charge is dead and i was really sick last night so i had no power to get out of bed and do charge up so i couldnt reply your email.

laptopの充電がなくなっていて、昨日の夜すごくsickだったから、ベットから起きて、充電する体力がなくてメールの返事ができなかった。

結構近い文章だと思うのですが、間違っている部分を訂正して頂けると助かります^@^

Sorry that I didn’t email you back last night. My laptop’s battery was dead but I was too sick to recharge it.

and i was really sick last night so i had no power --> no energy

to get out of bed and do charge up --> to recharge the battery
