Power was restored to Lowell House at 3:45 a.m. yesterday, after nearly 5 hours of power trouble.

The Engineering and Utilities Department received a call reporting power failures in different parts of the house at 11 p.m.

Power problems began in a few entryways. According to students, power for the whole house went out soon after midnight.

Engineering and Utilities workers from Harvard's University Operations Services arrived shortly after 1 a.m. to assess the situation and had the power back on by 3:45.
